_Brass worker._ Of the two boys of this group, one had served twelve months and the other twenty-four months at the trade. They earned respectively $5 and $6.50 a week and both intended to remain at the trade until it was learned. _Carpenter._ There were two boys serving as carpenter's helpers. With one it was simply a temporary position. The other had been working at the trade for a year, and although he was receiving but $4 a week, he intended to remain at the trade. _Electrician._ Three of the five boys working at this trade had been employed for over eighteen months as electricians' helpers. The other two had had four months and two months respectively of such experience. The five all expressed a determination to remain long enough to learn the trade. _Ship fitter._ The one boy in this group, although out of school over a year, had been working at the navy yard but two months. _Locksmith._ With only ten days' experience this boy was ready to quit. _Machinist._ The average time spent by the 14 boys classified as machinists was less than three and one-half months, and not one of the group had worked as long as a year. Three were running drill presses, 1 was cleaning the wheels and pipes of a feather-bone machine, 2 were not employed. Most of these were dissatisfied and looking for other work. A boy who had been working eleven months on a screwing machine, 1 who had worked nine months repairing autos, and 1 who had worked eight months as a machinist's helper--3 out of the 14--had worked long enough at the trade to know that they liked it, and expressed the intention of learning the trade. _Plumber._ Three of the four boys classified as plumbers' helpers had worked over a year and a half at the trade, liked the work, and expected to follow it. The fourth boy was using it as a temporary job. _Solderer._ The one boy in this line was dissatisfied with the job and with his pay. _Sheet-metal worker._ The one boy serving as a tin-roofer's helper had worked for the firm for a year and was perfectly satisfied with all conditions. There seem to be 14 of the 750 boys who had been working long enough at a trade and were sufficiently pleased with the prospects for the future to make one safe in saying that they would probably complete their apprenticeship--although this conclusion may not be justified. These 14 were distributed as follows: Blacksmith 1 Brass worker 2 Carpenter 1 Electrician 3 Machinist 3 Plumber 3 Sheet-metal worker 1 --- Total 14
