of reasonable probability, to enter a single trade. Hand and machine
composition, the largest of the printing trades, will serve as an
example. In a junior high school of 1,000 pupils, boys and girls, the
number of boys who are likely to become compositors is about five. But
to teach this trade printing equipment occupying considerable space is
necessary, together with a teacher who has had some experience or
training as a printer. The expense per pupil for equipment, for the
space it occupies, and for instruction renders special training for
such small classes impracticable. All of the skilled occupations, with
the exception perhaps of the machinist's trade, are in the same case.
An attempt to form separate classes for each of the eight largest
trades in the city would result in two classes of not over five
pupils, three classes of not over 10 pupils, and only one of over 13
pupils. The following table shows the number of boys, in a school of
this size, who are likely to enter each of these trades.

_Number of boys who will probably become:_
Machinists 36
Carpenters 13
Steam engineers 11
Painters 10
Electricians 9
Plumbers 7
Compositors 5
Molders 5
