Study Material Supplied to Educational Institutions 
As in my report for 1924, it is again pleasant to record the 
rapid growth of this part of our work. As was the case last year, 
this field has been in charge of my assistant, Miss Charlotte S. 
Young, who is building up and strengthening many lines of 
contact not only with the public schools but with colleges and 
universities. Over 300 requests for material were received in 
1925, and 162,585 pupils used study material of one sort or 
another, furnished by us. There has been an increasing demand 
for sterile nutrient agar supplied by us for the study of molds 
and bacteria. In this the Garden surely fills a very real need, 
for it would indeed be an expensive proposition for the City to 
install an autoclave and laboratory for each school where bacteria 
and molds are studied, such study occupying as a matter of 
fact only a small portion of each school year. At the Garden 
the autoclave and laboratory are a necessary adjunct of scientific 
research projects. The following table sets forth the growth of 
this work for the last 4 years.
