MIND AND HAND. 21 MACHINE FITTING. WHEN visitors enter the door of the machine fitting room, a rapid glance at the surroundings tells them that there is something interesting within. So they investigate farther and find many belts moving, wheels turning, and some blue jacketed young men adjusting their machine or fitting a piece of work in it. not so complete as those in the college shops, but it is of the latest improved pat- tern, and serves well for the amount and character of work done. Tbe outfit con- sists of seven large engine lathes, one planer, one shaper. and a number one and one-half universal milling machines, a speed drill, a drill press, one tool grinder, two coarse emorys, and also a tool room which contains tools for general use. MACHINE FITTING It is possible that these people have thought, previous to their visit, that it was not a hard task to work with and shape a a piece of wood into a definite form ; but now they are inquisitive to know the pro- cess of shaping a piece of rough iron or steel. This work is accomplished by the boys in this department through the aid of vari- ous machines. Our equipment is probably (4) The work is divided into two parts, re- quiring one year for completion. During the first half-year pieces of work are taken up which involve most of the principals necessary in making machine parts. The first work given to the class is a cast iron cylinder, to be cut to a certain length and diameter. The centers of the ends are first drilled and the piece placed between the centers of the lathe and revolved with the

20 MIND AND HAND. TURNING. w OOD-TURNING occupies the sec- ond half-year of the work in the technical department. The shop equip- ment for this course consists of twenty-five lathes, w ith as many benches, and a set of turner ' s tools for each pupil, besides a band-saw, jig-saw, universal trimmer and drill-press, which are for the shop in gen- arranged progressively. In the latter part of the term, however, some useful articles are made. Each pupil is required to make what is commonly known as a spool-box. It is an exercise in built-up work, and con- sists of twenty-five pieces, usually of two different kinds of wood. Besides this, each draws an original design, from which he makes a project. These are usually fancy vases, powder-boxes, match-safes or the like. It has been customary on our • WOOD TURNING. eral. Tools may also be obtained from the tool-room by any pupil on depositing his check. The work in turning consists chiefly of learning to use the tools and make the several different cuts, of which all turning, however complicated, is but a combination. The exercises are ten in number, and are annual visitors ' day for the turning classes to make small pine goblets as favors. The course gives a practical knowledge of small turning and a great deal of valu- able training. It is the first experience the pupil has in using a power outside his own body, and so opens up an entirely new field to him.

A taper cylinder is the next exercise, and is made by setting the dead center forward, or by the use of the taper attachment, and proceeding as with a straight cylinder. Our next piece is an exercise in square and V thread cutting, one of the most difficult for a beginner. The tool used for this work is ground square, or angular, accord- ing to the size and style of thread, and is fed automatically in a line parallel to the work by gearing, which is changed to suit the number of threads to the inch. Other forms of work, such as making and fitting collars on shafting, cutting fiat surfaces with the planer, shaper and milling ma- chine, are also taken up by each pupil. The present class began their second half- year ' s work by making some tools and use- ful machine parts, such as face plates for wood turning lathes, taper reamers for metal work, and some mandrels of various designs. Most of our attention, however, has been paid to the construction of a wood-turning lathe of the Putnam pattern. In this work each pupil is assigned a part of the rough casting; when he has completed the work on it another is given him. We have at present turned out most of the smaller parts and have made some progress with the large ones. The machine, when completed, will be the first work of this kind made entirely by the Industrial Training School. The two classes now in this department are not very large, but every member takes great interest in the work and believes that a great benefit will be reaped from it. Although Ave are not expert machinists we have a general knowledge of machinery, and the methods of its construction, as well as training in accuracy and neatness. H. W. Munsell. THE FORGE-ROOM. TOOTHING contributes more to the suc- JJ(9 cess which an institution attains than does the popularity and the spirit of satis- faction with which it is received. This has been true of the Industrial Training School from its beginning to the present moment. Especially lias the spirit of prosperity been noticed in the forging department. Year after year the classes have become more and more crowded, until, at the beginning of the last term, the advanced class was compelled to divide into two sections, each section taking alternate days in the forge-room. The work, on a whole, is very delightful and entertaining, afiordi ng a pleasing con- trast to the more confining duties of the class-room. Each boy is assigned to a forge, which has a full complement of tools. The first Aveek is spent in hammering lead, so as to become accustomed to the use of the hand- hammer. This is the hardest and most dis- agreeable work of the course ; but it is soon finished, and the real Avork is begun in iron. In the first half year the boy learns to forge the most simple articles, such as a hasp, gate-hook, etc. The most important part of the term ' s work is the welds. There are a number of Avays in which to make a Aveld, but the two most general ways are the lap and V Avelds. It takes a little patience at first to learn to do this work properly, but the boy soon mas- ters it. The Avork in the second term is on a larger and more difficult scale. It gener- ally commences with several pieces which require the use of the steam hammer. Work in steel is next taken up. Steel is very pleasant to Avork in on account of its elasticity, although much care must be ex- ercised to keep from overheating and burn-
