The course in wood turning includes: 1. Elementary principles: first,
straight turning; second, cutting in; third, convex curves with the
chisel; fourth, compound curves formed with the gouge. 2. File and
chisel handles. 3. Mallets. 4. Picture frames (chuck work). 5. Card
receiver (chuck work). 6. Watch safe (chuck work). 7. Ball.

In the pattern-making course the student is supposed to have some skill
in bench and lathe work, which will be increased; the direct object
being to teach what forms of pattern are in general necessary, and how
they must be constructed in order to get a perfect mould from them. The
character of the work differs each year. For instance, for the last
year, besides simpler patterns easily drawn from the sand, such as
glands, ball-cranks, etc., there were a series of flanged pipe-joints
for 21/2 in. pipes, including the necessary core boxes; also pulley
patterns from 6 in. to 10 in. diameter, built in segments for strength,
and to prevent warping and shrinkage; and, lastly, a complete set of
patterns for a three horse-power horizontal steam engine, all made from
drawings of the finished piece. In the vise work in iron, the chief
requirements are these: 1, given a block of cast iron 4 in. by 2 in. by
11/2 in. in thickness, to reduce the thickness 1/4 in. by chipping, and then
finishing with the file; 2, to file a round hole square; 3, to file a
round hole into elliptical; 4, given a 3 in. cube of wrought iron, to
cut a spline 3 in. by 3/8 in. by 1/4 in., and second, when the under side
is a one half round hollow--these two cuts involve the use of the cope
chisel and the round nose chisel, and are examples of very difficult
chipping; 5, round tiling or hand-vise work; 6, scraping; 7, special
examples of fitting. In the forging classes are elementary processes,
driving, bending, and upsetting; courses in welding; miscellaneous
forging; steel forging, including hardening and tempering in all its
details.

It is worth mentioning that in the industrial art school of the Purdue
University there were 13 of the fair sex as students, besides one in the
chemical school, and two going through the mechanical courses just
