In the latter part of July requests were received from a number of the nature-study teachers in the vacation schools. asking if we could loan them material for their work. Thirty—three schools were supplied with collections of birds, and ten schools with col- lections of insects. The collections of birds. in the four weeks which they were retained at the schools, were studied by 15,224 children: the collec» tions of insects by 7,000 children, making a total of 22,224 Thus more than tworthirds of the vacation schools in the city were using our collections.
