ron bed, fromA Post Drill 1250 400 365 350 50 to 80 40 The present equipment of the St. Louis school contains six-teen engine lathes, six speed lathes,^ two drills, one planer, oneshaper, two emery-grinders, two grindstones, a gas-forge, andabout a dozen vises. The gas-forge being in use only occasionally, needs no flue.The air-blast, which in the St. Louis school is furnished by aWestinghouse brake apparatus, may be produced by a foot or,hand blower, or by a connection with the forging-shop blast. THE CHARACTER OF THE TOOL INSTRUCTION. The students have thus far had no experience with metalsbeyond that gained in the forging-shop where heat was the i.The cold ch\sels and perhaps the hammers may have been made during thesecond year by the students themselves. 2 Two of these speed lathes have been made by the third-year class during thepresent year.

Now, however, the metals must be wrought cold. They areto be cut with the chisel and file, to be planed, to be turned,to be drilled, — in fact, they are to submit to processes verysimilar to those in use in the wood-working shop; but thetools are to be peculiar, and the methods altogether new to the boys. The steel tools must be strong, well-tempered, forged andground to specified shapes, and correctly adjusted. A failurein any one of these respects is a complete failure. In the following sketch of the functions of the different tools,and the exercises by which those functions are ttiught, noattempt is made at exhausting the subject. What I shall saywill be of value, not to the teacher who should be thoroughlyfamiliar with the theory and the use of every machine, but to the students themselv
