The type for the great newspaper is set up by linotype operators. Apprenticeship is rigorously limited. Some operators can never get beyond the 2500-em class, others with no more personal effort can set 5000 ems. Do the employers test out applicants for apprenticeship so as to be sure to secure boys who will develop into the 5000-em class? They do not: they select applicants for any near reason except the fundamental important one of innate fitness.
