DEP.-XRTMENT OF CHEMISTRY. JAMES H. SHEPARD, B. S. Professor of Chemistry ready to commence higher work. Next in o Chemistry. I-Iere he learns exact quantitative and to determine the percentage and eompositi and volumetric methods. The next course is o application of the wet method of analysis for a This department is equipped with the latest and most improved appliances for instruction. VVhen the student commences the subject he is assigned a desk provided with all the appa- ratus and fixtures needed. The first course of- fered is in Descriptive Inorganic Chemistry. This course makes the student familiar with the common elements. their compounds and tests up to the metals. Chemical theory is also included. The next course is Qualitative Inor- ganic Chemistry. This makes the student fa- miliar with the metals and the principles of qualitative analysis. Upon completing this course he next advances to the elements of Grganic Chemistry, which treat of the com- mon organic compounds met with in daily life as well as the classification and theories under- lying this branch. The object of these three courses is to give the student a good knowl- edge of general chemistry. He is taught its uses and applications. and now finds himself rder he enters upon a course in Quantitative methods. how to separate the different bases on of compounds. He uses both gravimetric ne in Volumetric Analysis. This teaches the ll the different organic acids and compounds and also their application and the determination of those inorganic substances which are more readily handled in that way. NVhen a s tudent has reached this point he is able to take up with benefit the Chemistry and Physiology of Foods. This course includes the princi- ples of nutrition, the methods of compoundin taries. At this point the student derives much benefit from the detection of adulterants, col- oring matter and preservatives as they are found in the prepared foods of our markets. After pursuing his course thus far. a few stu- dents who desire to specialize now take up Agricultural and Sanitary Analysis. where they learn the analysis of all kinds of foods, feeding stuffs. soils and waters. Agricultural students are also given a course in Agricultural Chemistry, which goes mi- nutely into the application of chemistry to everyday farm life. Finally students so elect- ing may take a course in Industrial Chemistry which has for its object a study of the manu- facturing processes in which chemistry enters so largely at the present time- It will be seen from the foregoing description that a student who has taken all the chemistry work in the South Dakota Agricultural College finds him- self well equipped indeed. g balanced rations and a study of human die- FRANK A.

- -Y - -.-- v-----.--.---,.- , t DEPARTMENT OF MECHANICAL ENGINEERING. The Department of Mechanical Engineering is located in the new Engineering and Physics Hall. The instruction in this department is both practical and theoretical. The usual methods of text-book study and lectures are employed, but the student is required to put into practice the instruction which he receives. Hence the work of the class room is supplemented and practically exemplified by practice in the shops and laboratories. In the drafting room the student is first taught the elementary principles of drafting. Then the design of individual pieces of different machines is taken up and finally a com- plete machine is designed. This involves the calculation of all the strains and stresses that are set up in the different parts of the machine. And also to make due allowance for strength and rigidity of each individual piece as it performs its function in relation to the whole mechanism. Among the many machines designed may be mentioned particularly gas en- gines, steam engines and straw boilers. In the shops the student is required to make some of the simpler machines that he has designed in the drafting room. Several courses are also offered in Architectural work fitting the student to make complete plans, drawings and estimates for ordinary buildings and residence. The machine shop is furnished with a large number of engine lathes for iron turning. These lathes are of various types and sizes. They are the products of the leading manu- facturing firms of the country and make the student familiar with the best makes of machines now on the market. We here also find a large iron planer, a sixteen-inch crank shaper, a No. 1 I-C: Universal Milling Machine, drill presses, drill grinders, etc., and a large number of smaller tools that go to make up a first-class machine shop. In fact it is doubtful if any college in the Northwest has a better assortment of representative machines than this college. In order to familiarize the student with the different machines and the principles of their operation he is given exercises in straight and taper turning, boring, thread cutting. planing, shaping, milling and gear cutting. And as his skill increases he is required to make various kinds of tools and cutters and finally to make complete machines from designs pre- viously made in the drafting room. In order to make the student as thoroughly familiar with modern machine shop methods as possible, he is required to acquire the habit of interpreting blue prints and drawings. As far as practical the student is allowed to use his own methods in the pro- duction of an article and encouraged in thinking for himself and exercising his own original- ity, and ingenuity. The forge room is furnished with twenty-eight forges and twenty-eight anvils, trip hammers, emery grinders, etc. The blast is furnished by a power blower and the gases are exhausted by a 70-inch steel-plate exhaust fan. The student is here given practice in drawing. bending, upsetting and welding iron and steel. Among the many articles that the student is required to make may be mentioned three pairs of blacksmith tongs, punches, chisels, various styles and sizes of wrenches and hammers. as well as a large number of other articles of practical importance. All these dif- ferent articles arc given a thorough test by the instructor as to temper and workmanship before they are accepted. The woodworking room is equipped with twenty-five sets of carpenter tools for bench work, and a large number of woodturning lathes, pattern lathes, jig saw, combination circular saw, large surface planer, etc- This makes in all a very complete woodworking equipment for bench work, woodturning and patternmaking. Here the student becomes familiar with the use of the different kinds of tools used in carpentry work as well as making all the joints common in building construction. On the wood lathe a person trains his eye as well as his hand. Here there is a possi- bility of developing something ornamental as well as useful. The :esthetic and the practical are combined. Here the student is required to make a number of cups of various sizes and shapes, spheres, mallets, picture frames and a large number of other articles too numerous to mention here. In the experimental laboratory we find a 100,000 pound vertical testing machine for the 16
