It was felt that some Fall sport should replace the game, and Association Football CSOccerj was in- troduced as an inter-class sport. The' game proved very suc- cessful, and an entire schedule was played, in which the Steam and Machine Design class, '09, won the greatest number of games. Over one hundred men played up to Thanksgiving. A 'Varsity team was also organized, but on account of the lateness of the season, it was impossible to arrange any but club team games, so no inter-school schedule was played.this year. N-ext Fall, however, promises to be a successful 'Varsity season. 21 5 'Varsity Association Football Team The 'Varsity Association Football feam played but one game with a team from Boys' Club of New York SCORE PRATT ........ 2 Boys Cr UB TEAM VV.

'03 40 Department Notes IVith this issue the Annual is making its ,appearance for the eighth time, carrying with it to the Alumni the greetings and congratulations of the Department of Science and Technology, and also a record of the growth and development of the several lines of the department's work. Each year it has been the cus- tom for the Institute to prepare an annual exhibit of the work in all the different clases, in order to show the students, teachers, and friends of the Institute the amount accomplished during the year. W'hat it has been possible to show at such ex- hibitions has been the results of work done by the students. This, however, is but a bi-product of our instruction. And, if the real work were to be shown, it would be necessary for all the graduates to return to the Institute and stand lined up for exhibition, each man bearing a placard showing the measure of his success in the work for which the Institute courses prepared him, and the character of the responsibilities which have since been entrusted to him. The extent of which the men who have gone out from Pratt, have made good in the practical work of life is a truer measure of the efiiciency of the Institute than is the character of the finished work they leave behind. It is manifestly impossible for the Alumni to return as a body on Exhibition Day, but, individually, in their various callings, Pratt men each year are proving to the world more and more that the ideals on which our institution was founded were not false ideals, and we point with pride to the record 'that they are making for themselves and for their Alma Mater. This record of our graduates we are proud of, and, as we send it out with this issue of the Annual, we wish, through the Annual. to express to them our congratulations. 41 Department Notes For this reason it is seemed worth while to print besides the addresses of the Alumni something more personal about the individual men, as it is felt that every one will be glad to know as much as possible about his own classmates and his friends in other classes. To those who have been away from the Institute for some years and who have not had an opportunity to revisit the Department of Science and Technology a few words of de- scription of its recent growth and development I am sure will also be of interest. There has been a considerable gain in numbers as will be seen from the tables of enrollment that follow, but not nearly so large a gain as there would have been, had it been possible for us to increase the number of our classrooms and laboratories and our equipment fast enough to make room for all of those who were properly prepared and whom we would have been glad to accept. There has'been, too, an increase in number, and a development in the courses of instruction, and a growth in the amount and the character of our equipment. This year, in the Department of Science and Technology, there have been admitted 367 men to the day courses, 828 men to the evening courses, and 63 men from other departments, making a total enrollment for the year of 1258 individuals. This is an increase of 55 over the cor- responding number a year ago. The most important gain in evening classes came from the establishment of a new course in Electrical Design which enabled those who 'had the proper preparation to carry their study in practical electrical problems farther than ever before. There were twenty-four men in this new class, eighteen of whom obtained our evening certi- ficate. In the day work there was a slight gain in numbers in each one of the older courses, and a larger gain in the 42 Department N otes new course in Applied Chemistry, which was established only two years ago last September. 'Some description of one of two lines of work included in this course were printed in last year's annual-the Soap Making and Leather Manufacture- so that most of the Alumni are probably familiar with these features of the instruction.

The articles printed in this issue of the Annual regarding the Physie Laboratories, the industrial 47 Department Notes Chemistry at the Institute, the improvements in the Mechanical and Electrical Laboratories will serve, however, to at least suggest something of the progress that is being continually made in the courses of instruction and in the material equip- ment of the Departmentg and the article on the Club House, the Athletic Notes, the record of the work of the various asso- ciations will serve to show how much greater are the oppor- tunities for social development and enjoyment offered to the students who enter Pratt Institute to-day. than were those enjoyed by the graduates of the early classes. In January of this year there was held in Chicago a National Convention of all persons who were interested in the growth and progress in Industrial Education. This Convention was largely attended by the people of Chicago and by prominent men and women from all parts of the United States. An attractive programme of addresses and discussions was ar- ranged and one of the prominent features was an exhibit in the large hall of the great Art Museum of Chicago. Pratt Institute prepared an exhibit for this occasion, as did a large number of schools, and I am sure it would have been a source of very much pride and satisfaction to all Pratt men if they could have seen and heard the favorable impression. and Hatter- ing comment which our exhibit created, for it was regarded by many as by far the most important and instructive exhibit present. X A photograph of this exhibit is shown in Figure l and three of the charts which were prepared to show statistics of the course and their growth are reproduced in Figures 2, 3 and 4, The exhibit was located in center of the great hall in front of the reproduction of the facade of a fine old French cathe- dral, which served as a most interesting back ground. It consisted of enlarged sepia photographs of the shops and laboratories with the classes at work, which were framed in 48 Department Notes brown quartered oak to matchg and in front on the long old table were displayed exhibits of patterns, castings, forgings, machine tools and machine parts, and manufactured chemicals, all of which has been made by the students at the Institute. Some other schools had good exhibits of' mechanicaliwork, but the Institute alone was able to show an exhibit of manufac- tured chemical products, and it was a satisfaction indeed to realize that Pratt Institute was the ,only school in America- probably the only school in the world--where men may be taught both the principles and the practice of manufacturing on a considerable scale a variety of chemical products repre- sentative of our great modern chemical industries. In closing these brief notes of the Department work and these few words of greeting to the Alumni from which, I am sorry to say, it has been necessary to omit many events of the year I would gladly have included, I cannot refrain from speaking of the increase of strength of the Alumni Spirit, and of the satisfaction that has come to the teachers, directors and trustees at the Institute from these new evidences of loyalty to Pratt brought to us through the formation of new alumni associations and local Pratt clubs and Pratt re-unions in different parts of the United States. ' ARTHUR L. NVILLISTON, I Director of Department of Science and Technology. 49 Recent Additions to the Physics Equipment A number of additions have been made, during the past year, to the equipment of the department of Physics, which have helped much to strengthen the work. As a partial list of these, the following may be mentioned: A complete Evans electro-dynamic equipment for lecture use, consisting of a small direct connected motor-generator set with armatures, field magnets, bearings, etc., all separable, so that various combinations may be made to demonstrate the fundamental phenomena of magnetism, induction, eddy cur- rents, etc. A .Bristol direct reading, double scale pyrometer, reading on one scale to 2,000 degrees Fah., and on the other 2,600 degrees Fah. This instrument is provided with fire ends and special protection tubes, and is being used at present to study the relative temperature of coal fires as compared with those of the gas and reducing furnaces in the Chemistry Building. A direct connected motor-generator set furnished by the Northern Electrical Company, consisting of a 3 H. P. variable speed 125 volt D. C. motor connected by a Hexible coupling to a 1 Kilowatt, single phase alternator. A Weston differential chain hoist, and a number of special pieces of apparatus, including Beckman's apparatus for the determination of the freezing point, a Meyer vapor density apparatus, special calorimeters, standard Green thermometers, Ives gratings, etc., and other apparatus in heat and light for use with the first year class in Applied Chemistry to closely relate their experimental work in physics with the instruction in chemistry. 50 Recent Additions to the Physics Equipment In addition to the development in the instruction in physics that has been made possible because of this increase in perma- nent equipment, the eliiciency of the work has been greatly augmented through changes designed to adapt th-e instruction more directly to the growing needs of the students in the various technical courses. A number of new and practical problems have been developed, which illustrate principles fun- damental to physics, and also to practical engineering work. Many improvements have been made upon apparatus already in use, and new models have been constructed in the Institute shops. The importance of the latter facilities for the construc- tion of apparatus of a practical character specially adapted to the needs of the men who come to the Institute cannot be over- estimated. The equipment for use in Physics, which the forge foundry, pattern, and machine shops have turned out during the year has been considerably in excess of that for any previous year. As equipment of this character, may be mentioned: two special prony brakes with water cooled pulleysg various elec- trical keys and switchesg special resistance coilsg models of a davit, shear legs and small trusses 5 a modified bicycle gear- ing for efiiciency testsg two model dynamos with single coil armatures for the study of induced E. M. F., a Hy wheel for the study of energy transfer in starting and stopping machin- eryg two air thermometers with attachmentsg duplicates of inclined planes, small cranes, etc. The articles which follow will furnish a definite idea of the character of some of this apparatus and of the type of practical problems and principles which it serves to illustrate, and will show the results obtained by th! students and the way in which they report them.

A PAIR OF SHEARS Figure 1 shows a pair of shears erected at Sparrows Point, Md., for the Maryland Steel Company.

In addition, a model has been made and set up in the laboratory. The students may compute the 52 Practical Problems -in fl'fC'C,I,tlllI-CS stresses in all the members for different set ups and then check their computations by testing the stresses in the model with spring balances. Figure 2 is a photograph of such a model pair of shears set up in the Physics Laboratories at Pratt. Institute. The legs are about 4 feet long, of IM inch oak. The feet are tapered and set in holes in the board M' N which is screwed Fm. 2. fast to the table, Several quick adjustments of the spread are thus possible. The legs are joined at A by a hinge, the pin of which passes through a clevis. By fastening a balance to the clevis and pulling up, along the line of a leg, until the foot just clears the support, the thrust at foot of the leg may be determined. The tie is of braided wire and, by an easy adjust- ment of its length, the legs can be inclined at any angle to the 53 Practical Problems in MCCl1'G11l1'CS vertical. A spring balance placed in the tie registers the ten- sion in that member. In this form, a pair of shears makes an easy and very prac- tical problem which can not only be solved, but the computa- tion can be checked by actual tests to within a few per ce11t. of variation, and the fact that it is a good-sized working model of a commercial machine, adds a large elem-ent of interest to the student's work. The method of solution usually followed in our laboratories is as follows: About a 20 pound load is hung at VV. The legs together weigh 2 pounds, and as one-half of this may be considered as acting at A and the other half at the feet, one pound is added to the weight W, in all computations. The thrusts in the legs may be imagined to be taken up by a single member in the plane of A B and A W, running from R to A fSee Force Diagram lj. VVe now have a simple case of equilibrium produced by three forces meeting at a common point. The stresses in tie A B and imaginary leg A R, are now found graphically or by trigonometry. Using the same methods, the force A R is then resolved into its two compo- nents along the legs, A C and A D. By adding to these values .7 pound, fthe effect of the remaining weight of the legj, the thrust at the foot is found. These results are then compared with the test readings taken as described.

THE CHAIN HOIST Among the different classes of machines the non-revers- ible type presents interesting problems in efficiency, displace- ment ratio, mechanical advantage, effect of load on friction, etc. By non-reversible type is meant a machine which will not be run backwards by the load when the driving effort is re- moved. To this class usually belong the screw, worm, differ- ential pulley, etc. !'i FIG. 3. Figure 3 shows a quarter-ton chain hoist which has been installed in the Physics Laboratories. It is a Weston Differ- ential Pulley type, made by Yale 8 Towne, and is the regular stock hoist of quarter-ton capacity and 8 feet lift. No effort has been made to reduce the friction or otherwise improve the apparatus. The test is meant to be strictly of a commercial character and under actual working conditions. 58 Practical Problems in Mccliantics This type of hoist was chosen for the beginner in prefer- ence to the worm and wheel hoist because the differential block CAD is open and allows the students to get at the mechanism Qtwo pulleysj, and so obtain measurements and observe its action. This block is fastened to an I beam. The load consists of an iron cradle and nine. 50-pound weights which may be added one at a time in order to test the machine under different loads from 50 to 550 pounds. The procedure is as follows: The diameters of the differ- ential pulleys are first measured and the displacement ratio computed from the formula where R is radius of large pulley and r the radius of the smaller one. This was then checked by measuring the length of chain running over large pulley, which had to be displaced in order to raise the load one foot. U The effort required to raise a given load is measured by pulling on a spring balance attached to the chain. As the machine will not run backwards, a negative effort, 17. c., an effort on the other side of same pulley, must be applied to lower the load. The amount of negative effort is determined in the same way as the effort required to raise the load. I-Ialf the alge- braic difference of these two quantities is approximately the value of the friction at that load. The output is computed by assuming load to be lifted 1 foot, thus: Output :f load X 1 foot-pounds. The input then equals the product of the dis- placement' ratio, by the effort to raise the load. By dividing output by input, the efficiency is found at the given load. This is repeated for loads increasing by 50-pound steps until a load of about 550 pounds is reached. Interesting curves are then plotted, showing relation between load and effort, load and friction, and load and efficiency. Below is a report of two students on this apparatus. VV. H.

This demonstrates that when there is no load, the driving ef- fort necessary to overcome friction is M pound, and that the friction and driving effort i1zcrca.sc proportionately to any in- crease of load. U The curve between efficiency and load shows that the effi- ciency is slightly lower at very small loads, but increases to about 30 per cent. at 75 pounds load and then remains prac- tically constant within the limits of the experiment. LOUIS DAH M, L. A. DlffXN, A' E 309' III. TI-IE CHAIN DRIVE EFFICIENCY 014' TRANSMISSION The chain drive probably has reached its maximum efh- ciency in the bicycle. In order to obtain minimum friction the teeth are cut very accurately and the chains are made with great care. Here, then, is one of the best examples of a common method of power transmission which is very easy to install in a laboratory, and which offers an interesting problem in max- imum commercial efficiency of a certain type of mechanical transmission. Figure 5 is a photograph of such a mechanism installed in the Pratt Laboratories. The pedals were removed and a wooden pulley having a radius equal to the length of the crank was attached to one crank. A pound applied to the rim of this pulley thus pro- duces the same torque as an equal force formerly did, when applied to the pedal.- A resisting torque is applied to the rear wheel by a weight on the cord running on the rim, from which the tire has been removed. If desired, the machine may now be driven by the force on the rear wheel. This will raise a greater weight on the pulley, thus gaining a large mechanical ad- 61 Pracfical Problems in Mechanics vantage. Or it may be driven in the usual way as a speed machine with the force on the pulley used as the driving effort. The latter is usually our practice. A two-ounce load is hung from the rear wheel and then enough weight put on the pulley to just raise this at a uniform speed. Then weights are removed from E until the load QLD lowers at the same uniform rate. Half the difference between these values Ceffort to raise and effort to lower the loadj rep- Fic. 5. resents the friction of the machine at this load. The driving effort for a frictionless machine can be found by taking half their sum. The input, output and efficiency are computed as in the experiment with the chain hoist, and curves plotted to show the relation of eiiiciency and driving effort to load raised. Also on the same sheet the driving efforts for a frictionless machine are plotted against the loads. The increase of friction with added loads is brought out by the divergence of the two 62 Practical Problems in Meclmniics effort curves. The displacement ratio is computed by meas- uring the diameters of the pulley and wheel, and counting the number of teeth on each sprocket. The computed value is then tested by actual measurements of the distances moved over simultaneously by effort and load. Below is the report of two students. I W. I-I. TIMBIE.

The curve does not pass through the origin because it requires some effort to drive the machine unloadedg the y intercept shows this effort to be M pound. The curve between loads and efforts for a frictionless ma- chine shows that these efforts are directly proportional to the loads themselves. This curve passes through the origin be- cause no effort would be required to drive an unloaded, fric- tionless machine. The curve between efficiency and loads shows that, within the limits of the experiment, the efficiency at first increases as the load increases, until, at a load of ZM, pounds the efficiency becomes practically constant at 97 per cent. .GARRET BRoDI11s.xn, R. P. THURs'roN, EA' Ee '09- 64 Praciical Problems in Mcchanrics DETERMINATION OF THE VALUE OF JOULE'S EQUIVALENT BY A SIMPLE FORM OF APPARATUS. Norte.-The apparatus shown in the Figure 1 was devised wholly from commercial parts, first to determine Joule'sequivalent, second to obtain a maximum value for the fraction of the energy input of an ordinary incandescent lamp which is turned into light. It consists of a 32 candle power bulb in a mieanite weather-proof socket, into which is screwed a short piece of brass pipe joined at the upper end to a wooden head. This head carries a pair of Fahnestock binding posts for the terminals of the lamp. The joints are sealed by beeswax above and below. Used in a metal calorimeter with a cover the apparatus converts the entire input directly into beat: while if the bulb is placed in a thin beaker of very clean water the light given off is apparently as bright as though the lamp were burning in air, but the heat developed is 10 to 13 per cent. less. This gives a maxinnnn value to the absolute eflicieney of the lamp in converting electric energy into heat. HARRISON ll. BROWN, lllf.S'fl'1It'f07. J ..- FIG. 1.-APPARATUS T0 DETERMINIQ IoU1E's EQUIVALENT. 65 Practical Problems in Mechanics -Ioule, a famous English physicist, found that the heat generated in a conductor carrying an electric current is propor- tional to the time, tolthe resistance, and to the square of the current. - We should at this point bring to mind two of the great principles of nature, namely the conservation and the trans- formation of energy. Substantially, they are, that energy may he changed from one form into another, but that it cannot be created or destroyed. When electric energy is applied to a con- ductor an exact amount of -energy always reappears as useful work, as heat, light or some other variety of energy. The electric incandescent lamp turns electric energy into heat and light. The light in turn may be changed into heat. We measure the electric input of energy in Joule's, which is the product of the amperes of current supplied by the number of volts dilference in pressure between the poles of the con- suming circuit, and by the time of the run in seconds. The heat unit is the calorie or the heat needed to raise one grain of water one degree centigrade. Since our apparatus H3.bSOl'lJSU the light and converts it into heat when we use the covered metal calorimeter, and since we know that there is a constant relation electric energy and heat energy, we may compare the energy supplied in joules with that developed in calories, and so determine how many calories to one joule. PROCEDURE.-A milliammeter is connected in series with the 32 c. p. lamps across the 110 volt circuit. A voltmeter is connected to the terminals of the lamp. A small resistance is sometimes needed in series with the lamp to bring the current inside the range of the ammeter.

UPTON, '09, 67 Industrial Chemistry Mixed Paint --As Made at Pratt In the Industrial Chemistry Laboratory of Pratt Institute we make what we guarantee to be an absolutely pure paint. There has been a prejudice on the part of most people, not familiar with the manufacture of mixed paint, against its use and up to wilthin the last twenty years this prejudice was so widespread that it seriously hampered the growth of the in- dustry. The consumers contended that where paint was made in such large quantities in the secrecy of the factory, there was too abundant chance for adulteration, and instead of the purchas- ers buying a pure lead and zinc paint, as the price would war- rant, they would pay a high price and get a grade of paint that contained barytes, known chemically as barium sulphate, which is cheaper than either lead or zinc and has not their cov- ering or wearing qualities. The paint makers of this country can well remember the time when a painter who was awarded a contract for painting a structure had to buy his white lead in oil and his tinting colors and then mix the paint by hand on the very premises wh-ere the work was to be done and under the watchful eye of the owner of the property. That this condition of affairs has been largely overcome we can see by examining the records of the output of ready-mixed paint in the United States for the last ten or fifteen years. This does not show or prove that the property owner of to-day is any less particular about the grade of paint he uses, but it does prove that the great number of mixed paint manufac- turers have been making an l1f0lIt'Sf paint, one that will wear 68 Industrial Chemist-ry a reasonable length of time under variable weather conditions. This is the way the confidence of the people in mixed paint has be-en gained and to-day we find that this industry has become so important and so well recognized that in the State of Iowa, for example, all the various kinds of- paint sold in its domain were last year analyzed by law at the State College and every paint not up to the standard forbidden to be sold in the State. We find at Pratt Institute that the best results are ob- tained by using as a base for our paint, equal quantities of white lead and zinc, and our method of manufacture is as follows: We place in a change can on our mixing machine equa.l weights of lead and zinc, together with the necessary amount of linseed oil. The oil must always be put in first and then the lead and zinc added slowly so as to give the oil a chance to take up all of the solid materials. If we wanted to make a white paint, the above would be all that would be mixed together in the beginning, but, of course, for any tint desired, appropriate tinting colors must be added with the lead and zinc. These materials are all mixed together until there is formed a thick, smooth-looking paste, a process which usually requires about two or three hours. The paint is then ready for milling or grinding and is transferred to a machine for that purpose, called an iron burr mill. When the paint comes out of here it is ground to a fine consistency, and all that has to be done now is the thinning, or in other words, putting it in a condition suitable to be at once brushed on to the wood. We place the ground paint back in a change can on the mixer and add what we call a standard oil, which contains our drier, etc. The mixer is run about an hour and the paint is then ready to can. We use at Pratt the friction-top cans and put up our paint in all sizes from the half-pint up to the gallon cans. Next comes the labeling, and then our paint is ready for the market. We 69 Ill0'1lSfl'lllf C11C7llI.Sfl'j' use yellow labels, having' printed upon them our guarantee that no barytes was uscd in the inamifactnre of the article. As paint does not come under the heading of food drugs, it is not necessary to print our formula upon the label of our cans, but that the reader may form some idea of what wc put into our paint, I will insert a characteristic formula, which is as follows: FILi.ll.-TPIE PAINT AND DYIQ Wmeics ,vr PRATT lNs'r1TU'rlc, 2,000 grs. white lead. 2,000 grs. zinc. 1,200 grs. linsecd oil. Thin with 2,800 grs. Standard oil. It can be seen, therefore, that we make a good paint, and that the Pratt Institute brand is a pure article, and also that we are being taught in the Chemistry course among other things to become skilled paint makers, a condition of affairs which can- not fail to strengthen this industry in the United States. GEORGE LA V,xr.L12ic, Applied Chemistry, '0S. 70 Iud11sl1'1'ali Clt61ll1'Sf7'j' The Manufacture of Pigments and Lakes The manufacture of ready-mixed paints and pulp colors are industries which demand some knowledge of chemistry. Until recently the manufacturer of these products has been guided by rule of thumb methods. The producer is now forced to acknowledge the necessity of chemical control of his output. It is in view of this fact that the practical study of this important industry is included in the course of Applied Chem- istry at Pratt Institute, where it is studied on sulliciently large a scale to illustrate present-day commercial methods. Our paint and color laboratory and factory are situated on the fourth Floor of the Chemistry Building. Here we have a stock room which consists of an arrangement of bins and bar- rels, all of which are labeled with the name of the contents, a balance, measures, etc. A stock of dry colors and chemicals is always kept on hand. This stock is purchased, or, where possible, is manufactured in the laboratory. In the latter ease the constituents of the required color are taken from the stock room. The laboratory is situated between the stock room and the factory. lt is furnished with the full equipment of a com- mercial laboratory, and in it all goods, both manfactured and marked, are analyzed for purity before being put into stock. The factory for the manufacture of the dry colors is fitted with a ten horse-power motor, of the direct current type, for power, a number of precipitating cans ranging from live to fifteen gallons capacity for precipitating the colors, a portable steam coil, agitation ball mill, vacuum pump. filter press, and a drying oven. One of the common pigments we manufacture is chrome yel- low. We have found by analysis that its formula is Pb CrO4 Qlead chromatej. Then knowing the weight of chrome yel- low required we calculate the required amount of chemicals Qlead acetate and sodium dichromatel that are needed. We 71 Industrial C hcmistry have found that twenty parts of lead acetate and fifteen and five-tenths parts of sodium dichromate are necessary for the reaction, and are then ready for work in the factory. XfVe dissolve twenty parts of lead acetate in eighty parts of water and dissolve fifteen and five-tenths parts of sodium di- chromate in eighty parts of water, and mix the two solutions. After standing a few hours the resulting chrome yellow can be washed by filling can with water and after the precipitate has settled syphoning off the liquor. Washing is continued until liquor is only slightly colored. Then the liquor and precip- itate is pumped into a filter press and from this it is spread on drying trays and placed in the drying oven. When dry the precipitate is powdered in the ball mill. Similar methods and precautions are taken with all other pigments, but with lakes a slightly different method is em- ployed. The aniline colors used are of both acid and basic nature. I will attempt to give an example of a process in each case. Basic color: Methyl violet. We mix with one hundred parts of barytes in five hundred parts boiling water, two parts of methyl violet, and stir well. When dye has dissolved add two parts tartar iemetic, then a solution of three parts tannic acid in one hundred parts hot water. On allowing to settle, if liquor is but slightly colored enough acid has been added, but if highly colored we add more acid. Allow to stand several hours, then the product-methyl violet lake-can be washed, filter-pressed and dried in oven. This is a process of precipitating the color on the barytes and it is similar for all basic colors: Acid color: Acid green. . We- mix fifteen parts aluminum sulphate CA12CSO4D3D in one hundred and fifty parts of water, with a solution of ten parts of acid green in one hundred parts of water. Then we pre- 72 Indushfial Chemistry cipitate this with thirty-two parts of barium chlorid QBEIC12, in six hundred and forty parts of water. On adding six and five-tenths parts soda ash in sixty-Five parts of water, the aluminum is also precipitated in the lake,-this producing complete precipitation. The action is to form a barium aniline color-the aluminum hydroxid formed carries down the remaining color precipitated on itself. For other acid colors the process is the same, only the color and per cents used being changed. ED. J. MURTfXGlI, IR., Applied Chemistry, '08, The Manufacture of Synthetic Oils at Pratt Synthetic methods of preparing organic compounds began in 1828 when Wohler synthesized urea. Up to that time it was supposed that organic compounds found in vegetable and animal matter depended upon a mysterious vital energy for their production. The synthesis of urea was followed by the preparation of acetic acid by Kolbe, and the building up of more hydrocarbons from compounds poorer in carbon by Frankland. The importance of synthetic research was thenceforth recog- nized, and it was, in fact, from artificial means of preparation that the constitution of many organic substances was first deduced with certainty. By the splendid work of such men as Wallacli, Tieman, von Baeyer, Remsen, Hoffman and Perkin, many compounds were synthesized, which had been thought impossible without the action of yital energy. At present a great many of the dyes, essential oils, and pharmaceutical prep- arations are produced by synthetic means. The study of synthetic chemistry at Pratt Institute begins in the last term of the first year with the study of simple or- ganic compounds and their methods of preparation. Con- 73 I ndusiria! Chemistry nected with this work in the class-room is the laboratory work, which consists in the preparation of chloroform, iocloform, ether and alcohol. The main object of the laboratory work is to teach the student to use the principles of synthetic chemistry which -he has learned in the class-room, and to use the right apparatus in the right place and for the right purpose. The study of synthetic chemistry is continued in the second year by a thorough course of laboratory work. Here inter- mediate products such as nitro-benzole, benzaldehyde, acetal- dehyde, napthol, benzoie and salicylic acids are prepared, and are later used to manufacture such products as oil of birch, oil of wintergreen, oil of anise, neroli, annamic aldehyde, and many other commercial essential oils. To illustrate the methods used in the preparation of syn- thetic oils at Pratt Institute, let us consider the following ex- amples: Q Oil of birch is prepared from benzoie acid and methyl alco- hol according to the following equation: CH3OH+C0H5CO2H:CclflnCOOCl'l:1-l-H20 The quantities of benzoie acid and methyl alcohol are cal- culated from the equation. The benzoie acid is dissolved in the calculated amount of alcohol, and the resulting solution is saturated with dry hydrochloric acid gas. Sulphuric acid is added drop by drop into the hydrochloric acid, which causes the liberation of hydrochloric acid gas. This gas is passed through concentrated sulphuric acid to re- move the moisture and finally passed into the benzoie acid solu- tion until the latter is saturated. The function of the hydrochloric gas is to act as a catalyzer thus enabling the benzoie acid to unite with the methyl alcohol to form methyl benzoate, which is the birch oil. To com- pletely saturate the alcoholic solution of benzoie acid with the hydrochloric acid gas requires about two hours for a volume of 74 Industrial Chemist-ry 200 cubic centimeters. When the saturation is complete the solution is dark brown in color, and has an oily appearance. The oily liquid is heated on the water bath for about two hours, to eliminate the excess of hydrochloric gas. A few drops of the oily liquid thrown into water will solidify if not completely boiled, thus giving an indication of when.complete combination has taken place. The liquid is now transferred to a separatory funnel, well washed, and the oil distilled over steam. The oil, on being dried over fused calcium chlorid, is a colorless liquid and is used as a flavoring extract. Synthetic oil of 'winfcrgreeiz or methyl salicylate is prepared in a similar manner from salicylic acid and methyl alcohol, ac- cording to equation: 4 CH::OH-1-Cf:H4CO2HOl'l: Clil'I4CO2C: l'l:sOH--f-H20 It is a clear oily liquid having a greenish tinge when in quantity. Art1'fic'1'al neroli is prepared from B napthol, methyl alcohol, and sulphuric acid. The quantities used, as calculated from equation, are five parts B napthol, five parts of methyl alco- hol, and two parts of sulphuric acid. The sulphuric acid is slowly added to the alcohol, and the resulting mixture cooled by running water. The B napthol is then added, and the mixture heated on a sand bath at l25oC, with a reflux condenser, connected for reduced pressure, and heated for six hours. The resulting product is thrown into hot water, which upon cooling causes the neroli to separate out as a yellow crystalline mass. These crystals are purified by dis- solving in hot alcohol and re-crystallizing. The resulting crystals are white, have a melting point of 700C and boiling point of 294 C. It is an important perfume, possessing a char- acteristic odor. Numerous other synthetic oils are also prepared, but owing to limited space will not be described at this time. MAX YTABLICK, Applied Chemistry, 'O8. 75 Recent Additions to Steam Laboratory Equipment During the past year there have been quite a number of val- uable and rather important additions to the equipment in the Steam and Mechanical Laboratory. These have included two engines, three steam pumps, and quite a variety of small or auxiliary apparatus, such as steam traps, safety valves, globe and gate valves, steam gauges, etc. Some of these have been for use in the laboratory, and some have been sectioned so as to show the details of their construction and mounted for lecture table demonstration. Two or three of the things are of sufficient general interest to warrant a description of them. The Institute has never had an example of an engine of a marine type in its laboratory and the only example of an engine with ia link-motion valve gear has been a small vertical engine for which such a valve-gear was constructed in our own shops. When an opportunity to obtain such an engine, of a size, power and floor space well adapted to our laboratory uses presented itself during the summer of 1907, the Institute was glad to se- cure it. This engine was built by the Reeves Engine Com- pany, and was one of two installed in a small steam yacht which sank in New York harbor in the fall of 1905 after being in commission only a few months. It was a compound engine of modern design, with a SM-inch H.P. cylinder, and QM-inch L.P. cylinder, and a 9-inch stroke, both cylinders having piston valves operated by Stevenson link motions. The front view of the engine as it is installed in the laboratory is shown in Figure 1. The acquisition of this engine presented to the Mechanical Laboratory some very interesting and valuable types of in- 76 Steam Laboraiory Equipment struction-work. The design, as well as the building of the foundations, the installation of all the piping, the fitting of the engine with a suitable governor and fly wheel-for as this was built as a marine engine it had neither of these parts-the lining up of the engine on its new foundations, and the renewal or the repairing of such minor parts as had become damaged, all were subjects which furnished the most use- FIG. 1.-THE VERTICAI. IVIARINE ENGINE. ful kind of problems for student instruction. All this was done in the laboratory by theestudents as a part of the regular laboratory instruction, and its successful accomplishment is attested to by the fact that the engine is now running as a regular part of the equipment smoothly and as perfectly as any engine could be expected to run. In undertaking work of this character with students, in order that all may profit 77 Steam Laboratorv Equipment to the greatest extent by the instruction, each step must be carefully planned in advance and detailed drawings must be prepared, so that every one may understand it and make the portion of it, which may be assigned to him, fit exactly with the general scheme. In this installation after the drawings for the concrete foundation had been prepared, and the location on the labora- tory fioor finally approved and marked out according to the drawing, the excavation was made. Wooden moulds were then constructed for the concrete, templates prepared to locate exactly the foundation bolts. T-hesc bolts and their anchor plates were then set in place and the work checked to be certain that no mistake had been made. After this had been done the concrete was mixed in the proper propor- tion and carefully rammed in place. As the foundation was quite irregular in shape in order to fit the curved and irreg- ular base and to provide for the fly wheel, a good deal of skill 'and ingenuity was needed to be sure that every part of the mould was properly tamped and filled. When the concrete had thoroughly set, the moulds were removed and the founda- tion was smoothed and finished with neat cement. It is hardly necessary to describe in detail every part of the work-the jacking up of the engine to get it on its founda- tion or the lining it up after it was in place, determining the layout of the exhaust and the steam pipes, so that the engine could be run either condensing or non-condensing, selecting and locating the separator and the governor, or provid- ing for the drip pipes of the cylinders. Enough has been said at least to suggest the character of the problems which were furnished for student instruction. In undertaking the repair of this engine the same idea was used as in the installation--that of using systematically every step of the work for training and student instruction. The 78 Steam Laboratory Equipment crank shaft was taken out and tested and found to be slightly out of true. The journals, therefore, were reground, and all of the bearings and caps rebabitted and then scraped to give a perfectly uniform bearing for the shaft in a posi- tion exactly parallel with the line of the cylinders and at right angles to the center of their bore. Both the high and low pressure valve-gears were completely overhauled, new link- bloeks and pins made throughout and new bushings fitted wherever they had become worn. Before the engine was as- sembled, too, every part was tested to see that it measured up to the required standard of accuracy. Problems of the kind encountered in both the installation and the overhauling of this engine are precisely the kind that Pratt students will encounter again and again in their practical work after they leave the Institute. They are, forthe most part, problems requiring great skill, care, and intelligence, and. too, therefore, furnish the best possible opportunity for training. The benefit derived from this type of instruction was felt to be so great that a second engine was secured to furnish simi- lar problems for other students. This engine was an 8 x 10 horizontal engine. which had been used for driving a blower in a local factoryg but which had been recently discarded, because it was so badly worn. It was temporarily installed on the laboratory floor and securely bolted to heavy wooden blocking. Then it was completely overhauled, and in many parts rebuilt, and now is in excellent running condi- tion, ready to be permanently installed in the laboratory as soon as its foundation is completed. To take an engine in the condition in which this horizontal engine was, when it was delivered to the Institute, to find all of the points at which it is at fault and what is required to put it in proper running condition, to plan this work, step by step in systematic order and carry the work thus planned to 79 Steam Laboratory Equipment a successful conclusion requires just the same kind of mechan- :ical judgment as is every day being demanded of those superintending important manufacturing operations, and no type of work can offer better training or preparation for those F119 2.-Two STEAM PUMPS IN Tmc STEAM LABORATORY, who wish to well equip themselves to enter such industrial establishments. Figure 2 shows two of the pumps installed during the year in the steam laboratory, the founda- tion and piping of which was planned and carried out in the 80 Steam Laboratory Equipment way just described. One of these pumps was manufactured by the Henry R. Worthington Company, and the other by the Platt Iron Works, Dayton, Ohio. It would be wrong, however, to give the impression that all of the instruction in the steam and mechanical laboratory is of the character described above. The -testing of machinery and the measurement of its efficiency is important, and is given a proper place in laboratory work of the lnstituteg but this testing and determination of efficiency becomes more vital and instructive, when the purpose of such investigation is to determine something useful of itself, such as whether or not a piece of apparatus is in proper condition for service, or whether an installation or overhauling of a given machine has been done well. It is important to understand the principles on which a given machine is designed to operate, but it is equally important to understand the principles involved in making that same machine perform satisfactorily and do its most perfect work. As an illustration of different 'type of work which comes in as a part of the steam laboratory instruction might be men- tioned the test of the United States Steam Lighter Transfer of the Paymaster's Department of the New York Navy Yard, for which the second year Steam and Machine design class has made careful preparation. The Transfer is a steel cargo lighter for handling supplies to and from the various railroad docks and the Navy Yard. She is ll0 feet long on the water line, with beam 30 feet, and her loaded-draft is ll feet. Power in supplied by a vertical compound engine, exhausting into a surface condenser. The test will be made on an all day run up the Hudson River from Brooklyn to Iona Island, where is located one of the largest naval powder magazines in the United States. During the run complete observations of boiler, engine, con- 81 Steam Laboratory Equipment denser, and auxiliary apparatus will be taken from which will be determined the efficiency of each. MACHINE DESIGN EQUIPMENT. We have been very fortunate during the past year in secur- ing a large number of models or parts of working machines for use in the instruction in machine design. These models for the most part have been donated to the Institute by manufac- turers, to whom we wish to express gratitude and appreciation. A partial list of those added to the collection is given here: A complete set of engineers' wrenches, mounted on a wrench board, presented by the H. Williams Co. A complete set of standard bolts and nuts, presented by the Runsel, llirdsall Sz XVZl1'Cl Company. A section of the casing of a Singer sewing machine, show- ing all the working parts. A vise presented by the Rock Island Tool Company. A Harrington travelling hoist, presented by Edwin Har- rington Sz Son. A Garvin Milling Machine vise, presented by the Garvin Ma- chine Company. A Davidson Pump steam chest and a water valve, presented by M. T. Davidson Company. A 6 universal chuck. A friction clutch. A shaft hanger, pulley and tlanged coupling, presented by the A. 8: F. Brown Co. A complete harvesting machine knotter. A set of expansion bolts. A pillow block. A model worm and gear. Twenty-live boards upon which are mounted various sizes of set screws, cotterpins, split pins, lock nuts, lag screws, Wing nuts, taper pins, washers. stove bolts, and commercial pipe fittings of all descriptions. M. C. MAXWELL, Head Instructor, Applied Mechanics 82 Electrical Laboratory Improvements During the past year a number of improvements have been made in the electrical laboratory, and its appearance has been. greatly altered. It still occupies the same floor space as formerly, but the removal of the partition that divided the laboratory into two parts-has made it possible to use the existing room to better advantage. A concrete floor has re- placed the old wooden oneg the greater part of the entire equipment has been re-installedg and some greatly needed new apparatus has been added. Those who have known the laboratory in tl1e past years will be interested to know something more in detail of these changes. An idea of the present appearance of the main portion of the laboratory may be had from the recent photo- graph which is reproduced in Figure 1. 'lfhey will also be interested in some of the recent improvements, which have been introduced, for the most part, for the purpose of putting at the service of the student such complete facilities for ex- perimental work that he would be able to carry to a successful conclusion the tasks assigned him without being obliged to waste his time in devising temporary or inadequate make- shifts of his own, or without being needlessly hampered in any way in performing his experimental work. In the re- installation of the machine equipment the motors and genera- tors have been direct-coupled in pairs, each pair being mounted on a steel frame or stand with a shelf for the instruments on the same level as the base of the machines and a small switch- board panel on the side of the frame. On the latter are mounted switches, which control the supply of electric power, and also the terminals of lines leading to lamp-banks 83 Electrical Laboratory Inztprovcmants and to other parts of the laboratory. These small switchboards have taken the place of the large central switchboard, with lines radiating to all parts of the laboratory such as are commonly employed in school and college labora- tories, and have thus much simplified the equipments. The central switchboard is always very cumbersome in construc- FIG. 1.-THE Morox ANU GENERATOR IZQUIPMIQNT. tiong and, in operation-wherever there are large laboratory classes such as we have at Pratt Institute-it is always a source of endless trouble and confusion. The new method of installing the machinery may be seen clearly in Figure 2, these particular machines being a five 84 Elcctrlral Laboratory I71lfJl'0'UC7lI'C'llfS horse-power, three-phase variable speed induction motor and a three kilowatt compound generator. The auxilliary equip- ment which is shown in Figure 2, such as the rheostats, instru- ments, switches, and connecting cables is all strictly portable and is removed by the students on the completion of the ex- periment, leaving both the machines and stand stripped as shown in Figure 3. This gives the laboratory a neat and .?' IFIG. 2.-MOTOR GIENERATOR SET WITH AUXIl.l.I4KRX' EQU1PMi-:NT. orderly appearance. The students who next use these ma- chines secure the needed auxiliary equipment from the stock room and assemble and connect it according to the require- ments of the experiment that they are to perform. This new arrangement of the electrical machine equipment is but one illustration of the betterments that have been intro- duced in the laboratory. The object of each has been to 85 Electrical Laboratory Improve-ments increase the efficiency of the work and make it possible through the saving of time effected, to broaden and to extend the scope of laboratory instruction. And lest criticism should be made that too many conveniences are provided, that may rob the students of opportunities to exercise their own origi- nality ancl resourcefulncss in overcoming obstacles, it should be stated that this possibility is avoided by requiring them to Fics. 3.-Moron GIQNIQRATOR SHT WIT!-mUT A Ux1I.i.lARY EQUIPMENT. install all the equipment and construct many portions of it. This systematic training in planning, designing and installing the details of equipment to facilitate the work cultivates their resourcefulness most effectively, and constitutes a valuable feature of the laboratory work. With the exception of the bare machines, the switches, the instruments and the rheostats, all portions of the equipment 86 Electrical Laboratory Improfuemenfs shown in Figure 2 were constructed, and the entire in- stallation performed by the students. The method of laboratory instruction is to permit the student at one time to concentrate his entire attention upon the performance of the experiment and at another time to concentrate it upon the construction or the installation of laboratory equipment, both parts of the work being always under the systematic direction of the instructor. The practical results of these methods have been both a greater accomplishment in a given time, and also -and of greater importance-a very decided benefit to the student, from learning by personal experience, the very great value of systematic methods of work. The laboratory facilities along the line of electrical machinery have been somewhat strengthened, too, during the year by the purchase from the Fort Wayne Electrical Works of four ma- chines, which, as installed, constitute two direct connected motor-generator sets. One set consisting of five horse-power, three phase, variable speed induction motor and a three kilo- watt compound generator is shown in Figure 3, and Figure 2 Shows the same set connected so as to operate as an induction generator, illustrating one of several ways in which the set may be operated. The other set consists of a five horse-power shunt motor and a three kilowatt, three-phase generator, and may be seen in the upper left hand corner in Figure 1, which :shows the set in use as a direct current motor driving a three- phase generator, though it may also be used as a synchronous motor driving a shunt generator.

SUMMER EDMANDS, Head Instructor in Applied Electricity. 87 The Pratt Institute Club The new club house has completed the second year of its history, and has more than met the expectations first enter- tained for it by those interested in its creation. The Institute courses do not allow much time for recreation for the men who are in attendance during the day, and for the men in the even- ing courses, there is even less opportunity between the demands of their day employment and their evening classes. Still, there are in the case of almost every individual some moments of spare time, some breathing spells, between the intervals of serious work, which offer opportunity for recreation and en- joyment and social intercourse, that are becoming a more and more important part of the student life at Pratt Institute. Each year the students are realizing more fully than before that, even though they come to the Institute alone for the serious purpose of technical instruction or practical work, they fail to get all that is open to them if they do not in a rea- sonable and sensible way find rest and relaxation from their earnest work in one way or another, and if they do not improve such natural opportunities as are open for making friends and increasing their knowledge and faith in their fellow men. It has been the purpose of the Club, and of the various com- mittees that have had its management in charge, to have the club house, so far as possible, the natural meeting place and center for this part of the student life, and where time must be economized as carefully, as it always must at Pratt, the ad- vantage of having a social center so near at hand has been very greatly appreciated. It has made it possible for the stu- dents to utilize the few moments in the afternoon between dusk and dinner time or a portion of an evening, whenever the 88 The Pm!! Insfifntc Club whole time did not have to be given to studyg it has made it possible too, to improve the few vacant periods that occur during the week when no definite work is assigned, and it has made the noon period much more valuable. During the year, these intervals, short as many of them are, have offered the opportunity for meetings between friend and friend, which have created a kind of comradeship throughout the classes and a friendly intimacy between the different classes that was not possible before the Club was built. 1 1716. 1.--THE CLUB READING Room. The alumni, too, have been finding more ways in which the club house could be of use to them, and many alumni gather- ings of all sorts have been held at the club during the past winter. Some of them have been formal class or alumni dinners, and others have been the most informal kind of meetings of small groups of intimate friends. While at the Institute the men in the various classes are kept close together by their reg- ular work, but after graduation there was little or nothing to hold the men together before the Institute Pratt Club was 89 The Pratt Institute Club planned and built, but this now offers such a natural meeting place for the men, who during their Institute life formed the habit of congregating here, that in many, many instances-too numerous to count-friendships have been kept up and old ties maintained and new and valuable acquaintances made through- out all the alumni organizations. It has been an ever puzzling question to know just how to make the attractions which the club might offer in the way of recreation and entertainment and social intercourse, best meet the desires of more than a thousand men, all differently situa-ted, and with almost as many temperaments, but with what success these difficult problems have been met and with what apprecia- tion the efforts to find things that would have a common inter- est to all, can best be judged from the record of growth in membership, and the increases in the use of the club house facilities. A year ago the Executive Committee passed a reso- lution whereby any class or any alumni association joining the club in a body could do so at one-third the regular individual rate. Every class in the Institute, small and large, with hardly a single exception, took advantage of this privilege, and to-day it may be said that practically every day student at Pratt is a member of the club. There were one or two classes in which there were two or three members who were so situated that they were unable to use the club and who were unable to spare the amount required as their share of the dues. With the best of good will, the difference was made up by the re- mainder of the class, and the students referred to were pre- sented with free tickets of membership, in order that the others might have the privilege of the reduced rate and the satisfac- tion in having their class represented as a whole. The fact that the entire student body of the Institute is co-operating with this kind of spirit in the support of the club for the good of 90 The Pratt Iustilule Club all, bears the most emphatic kind of testimony to the general appreciation of the club's work. The social activity throughout the year that is just past has been in many directions. There has always been something going on, sometimes of one kind, sometimes of another. There have been dances, lectures, ladies' nights, bowling tournaments, class and alumni dinners, minstrel shows and dramatic per- formances, formal class meetings, and informal meetings or smokers. Some of these are of sufficient interest to warrant referring to themniore in detail. For example, there have been several formal lectures given by representative business men on important technical or prac- tical subjects, as follows: Mr. S. N. Evans, of the Pilcher Lead Company. Mr. R. 1-I. Lisner, member of Charles M. Childs Sz Co. Mr. H. L. Williams, of H. L. Williams Sz Co. Mr. William J. Kaup, this year at Cornell University. Mr. L. Loring Clarke, of the N. Y. 81 N. J. Telephone Co. Mr. R. S. Church, of the Barrett Mfg. Co. Dr. A. C. Langmuir, on Glycerine Productsf, These lectures, at which there were in attendance an average of seventy-five individuals, received much commendation and proved most beneficial to the members in their respective lines of study. During the year there were from twelve to fifteen dances, a few of which were ladies' nights, given by the club to all the club members. There were twenty-three smokers, several of which were given by evening classes and by alumni asso- ciations. There were a large number of business meetings of both classes and alumni organizations. There were a large number of both billiard and pool contests, and many other entertainments. The bowling tournaments, both at home and abroad, were 91 . , r fx 4, , , Q A .' .- - A Q I. , - I .-of .-4 w .

The inter-class bowling tournament, in which there were seven teams entered, including one made up from Pratt Insti- tute instructors, one from alumni members, and five from dif- ferent classes in the Institute, was probably the most interest- ing bowling series of the year. Night after night the teams met, each consisting of five men, to contest for a prize, a beau- tiful silver bowling ball upheld by three bowling pins. The alumni team won, but was closely pushed by both the Faculty team, and the Steam and Machine Design team of 1908. The highest score was rolled by Mr. Field, A. F., '98, who rolled 233. Mr. Jamison, of the Faculty team, won the prize for the individual high average with a score of 162 2-5 for the eighteen games. The result of the contests in detail is as follows: GAMES XVON GAMFS LOST AVERAGE Alumni team ........ 16 2 .888 Faculty team .......... . 12 6 .667 S. 81 M. D. '08 team ..... . 11 7 .611 A. E.

Applied Electricity, '09, won with a perfect score, or an average of 100 per cent. Hawley and Dean represented their class on this team and were more than a match for their opponents, winning every contest and playing. at all times, ex- cellent pool. Probably the most popular innovation that has been made during the year, however, was the throwing open of the club at noon, in order to serve a luncheon to the club members in the Entertainment Hall on the top floor. Tables have been set . 93 The Pratt Institute Club up the entire length of the room, the luncheon consisting of inexpensive hot dishes, soup, sandwiches, fruit, cake and pie, dairy dishes, coffee and milk has been served from a side table. This noonday lunch has met with a hearty response and has been popular from the first, and every noon. no matter what the condition of the weather, the club has been a scene of activity. There have been on an average of sixty to sixty-five luncheons served a day. The greatest number served at any one time has been ninety and the lowest forty-eight, but, in addition to those who came to get their lunch at the club, many students who had eaten their lunch at their regular boarding place would drop in for a few moments, knowing that they would meet their classmates there, to talk over athletics or some topic of interest, or simply to read the papers or mag- azines. Often, in this way, there have been over a hundred students and instructors-for the instructors have patronized this ,noonday lunch quite generally-in the building at noon, bowling, playing pool, and in general conversation. Thus the simple noonday lunch has helped more than any other single thing to make the club regarded as the natural meeting place, not only at this time of day, but at all times when a half dozen or a dozen Pratt men wish to congregate. The oHicers and the committees of the club for the year 1907-O8 are as follows: President ............. ...I-I. A. RUETSCHI Secretary ............. .... C . W. DILLON First Vice-President ..... .....

The Aeolian Company has installed Pipe-Organs in many of the most famous residences throughout America, as well. as Europe. Ranging in size from small to very large instruments, these organs are furnished with com- plete manual ano pedal keyboards and with all the requisite mechanical ap- pliances for the use of the skilled organistg they are also provided with a self- plciying device ivy which compositions can be edectivcly rendered by anyone with the aid of music-rolls. These music-rolls, which can only be used on Aeoliun Pipe-Organs, permit of the free and independent use of each manual, so that every solo and accom- panimental edeci produced by an organut can be duplicated by persons with- out musical tramingg furthermore orchestral and entirely new organ effects are made possible which cannot be obtained when the organ is played from the keyboards. To remove all ditticulties from the way of the performer .in producing the correct tonal or orchestral effects, the Aeolian Company has devised a system of Tone-markings which appear on each music-roll, ny which the performer is directed at each stage of the music as to which stops and combinations are required. . The Aeolian Pipe Organ is not only a home orchestra, but the organ par excellence of the present time, an exclusive type of instrument, embodying tonal and mechanical features contained in no other organ.

A leading medical authority has recently said:-' 'One out of seven of all the people who die is prematurely carried off by tuberculosis, and a large propor- tion of these through dust poisoning, which if we choose we can largely prevent. Medical authorities are constantly calling attention to the danger from the disease-ladened dust in public places, and it has been shown beyond question of doubt that the remedy lies in the proper treatment of floors. For this pur- pose there is nothing equal to TANDARD Floor Dressing One of the many tests made by a well-known authority showed that where Standard Floor Dressing was used the atmosphere was twelve times as free from dust as that in rooms and corridors in which the dressing was not used. Another test showed that floors treated with Standard'Floor Dressing rendered harmless ten times as many germs as a dry wood floor. These trials . A conclusively prove the value of Standard Floor Dressing as a , preventive of circulating dust and the accompanying danger from disease contagion. In addition to preventing the circulation of dust, Standard Floor Dressing preserves the flooring and reduces labor. Will not evaporate. Pays for gsels manmltimes ovgr. Three or four applications yearly with ' I I patented lan sr er gives es resu s. We will apply Standard Floor Dressing. without charge, to the floor of one room or hallin any Hospital, School, or other public building, to demonstrate that allwe claim for it is true. Standard Floor Dressing is not intended for use on varnished, waxed or polished floors or for use in private houses. U Sold everywhere in barrels and cans of varying capacity. Testimonials and interesting reports from medical authorities on floors which have been treated with Standard Floor Dressing gladly furnished upon request.

When you think of E S - reliable valves, associate the name of I Q B L 2 A' l l and the location- CINCINNATI. l'ID!iME1Il THE POWELL WHITE STAR is in a class all by itself. There is no valve now on the market that competes with it. lt's the only valve made in which the disk is regrindable, reversible and renewable, that is, the disk has two faces, both of which can be reground any number of times. When one face is wom it don't mean putting in a new valve, simply take the trimmings off, turn the disk upside down and you practically have a brand-new valve without one penny's expense. When both faces of the disk are worn, buy a new disk, don't buy a new valve. 1-ll For high pressure and superheated steam this valve is without an equal anywhere. For some purpose a vulcanized fibre washer valve is preferable. We make that kind built on exactly the same lines as the White Star, the only difference being in the disk and the construction thereof. Our valve is ever-so-much easier taken apart than other makes. There is no red lead required to make the threads steam- tight. The large hexagon swivel nut that holds the bonnet to the body never sticks, never binds, but is readily unscrewed. The disk is held in a very simple and much improved manner. q Send for booklets distributed by iobbing supply houses everywhere. ql lnsiat upon the POWELL when order- ing valves and luke no substitute.
