Read the excerpt from "At School."

Practical job training was important. Many kids went directly from grammar school to special vocational schools sponsored by private agencies like the Children's Aid Society in New York City. The society operated separate trade schools for boys and girls. The courses offered reflected the kinds of jobs open to the students. For boys: shoemaking, printing, carpentry, sign painting, bookbinding, basketry, chair caning, janitorial work. For girls: cooking, sewing, embroidery, dressmaking, millinery, stenography, typewriting.
