that each student, in each section, can lock up and control his own tools and instruments, which are not to be used in com mon. The Course of Study.-1. Design a series of progressive lessons, especially adapted to teach the use of the set of tools and appliances pertaining to each course. 2. Let the master work each lesson, or sample, that he may settle clearly in his own mind the best method of solution, with a statement of the reasons therefor. 3. A system of inspection upon which the quality of the work can be based, and each student given his proper percentage, and which shall also be the means of educating the judgment of the student, that it may keep pace with his skill of hand to execute. We find, then, that in this practical part of the problem there are three distinct educational steps. First, the best method of solution. Second, skill of hand to execute the work. Third, the capacity to judge of the quality of the work. The theoretical studies are arithmetic, algebra, geometry, English, physics, and drawing. The shops are arranged for teaching sixteen in a section, except that for forging, which contains only eight forges, on account of the smallness of the room. The deficiency has been remedied as far as possible by enlarging the foundery, and using portable forges. All our shops are entirely too small for the work we are endeavoring to do in them, and the present temporary building must soon be replaced by a larger and better adapted one, if the purposes of the school are ever fully realized. The Carpentry, Joinery, Wood-Turning and Pattern Shop. This shop is 50' by 20', one end containing the carpentry and joinery benches, and the other the wood-turning lathes shown in the cut. The lathes are placed four on each side of two benches, and under each lathe are four drawers to hold the tools of the four sections. The carpentry and joinery benches at the other end of the room are similarly arranged. In the middle of the room, the cut shows the saws for cutting up the lumber to the dimensions needed in the courses of instruction. The first instruction in carpentry and joinery is the use of the saw and plane in working wood to given dimensions, and then a series of elements follow in order. (See cut.) No. 1, a square joint; 2, a mitre joint; 3, a dovetail joint; 4, a blind dovetail; 5, a mitre dovetail; 6, a common tenon; 7, a key tenon; 8, a tusk tenon; 9, a brace tenon; 10, a pair of rafters with collarbeam; 11, a truss tenon; 12, a drawer; 13, a panel. In addition to the above each student makes a small frame, to apply several of the elements of the previous lessons. A sample is given in the cut. The instruction in turning (see cut) and circular-section pattern-making is given in the following series of models. Nos. 1, 2, and 3 represent a series of manipulations in simple turning; 4, 5, and 12, pulleys; 9, a globe-valve; 6, 7, 8, 10, 11, 13, 14, patterns for various forms of pipe. Corresponding core patterns form part of the course. Bench patterns, and bench and lathe combined, are not included for want of space. The instruction in this shop is given by Mr. George Smith, assisted by Mr. Z. Nason. The Foundery. The cut representing the foundery shows a part of the sixteen moulding benches, combined with troughs for holding the sand, with the cupola furnace at the other end of the room. Over the furnace is seen the Sturtevant fan, which exhausts the heat and dust from the blacksmith's shop beyond. The furnace connects with a flue which passes out of the shop, thence underground, into a chimney in the rear end of the main Institute building. The blast for the furnace is taken from the pipe shown over the door, in the rear right-hand corner of the room. An average charge of the furnace is about five hundred pounds. Foundery Course.- Nos. 1, 2, 3, 4, 5, are pieces used in the course of filing and chipping; 6 and 7, curved castings; 8, a sheave; 9, a pulley; 10, a pulley; 11, an eccentric; 12, a clutch; 13, 14, 15, 16, 17, 18, 21, parts of a loom; 19, 20, cogwheels; 22, a rack; "23, a shield. |
