Work is done wiTh ferrous lgrey ironl ond non-ferrous lbrciss cind dluminuml meTo1ls. A boy is re- quired To spend d sufficienT lengTh of Time on edch uniT To insure ci working knowledge of foundry procedure, cmd Then he is ossigned To more complicdTed work on The uniT for which he shows gredTer c1pTiTude.
