Public nurseries for U.S. war workers' children After a warm meal at noontime, these American children take off their shoes for their nap in their public nursery, one of forty-one servicing an industrial area of thirty miles on the western U.S. coast. Their parents are working in a shipyard and their nursery school was established through funds appropriated by the U.S. Congress for the benefit of war workers' children. The nursery is open from six a.m. to six p.m.
