He would next be
taught how to shape the simpler geometrical forms in the materials of
his trade, getting out a straight prism, a cylinder, a pyramid, or a
sphere, of such size and form as may be convenient; getting lines and
planes at right angles, or working to miter; practicing the working of
his "job" to definite size, and to the forms given by drawings, which
drawings should be made by the apprentice himself. When he is able to
do good work of this kind, he should attempt larger work, and the
construction of parts of structures involving exact fitting and special
manipulations. The course, finally, should conclude with exercises in
the construction and erection of complete structures and in the making
of peculiar details, such as are regarded by the average workman
as remarkable "_tours de force_." The trade school usually gives
instruction in the common school branches of education, and especially
in drawing, free-hand and mechanical, carrying them as far as the
successful prosecution of the trade requires.
