/ Boy Scout Exhibit 



From May 4 to May 11 an exhibition of scoutcraft models 

 was held in the Exhibit Room of the Laboratory Building. 

 These models were made by Brooklyn Boy Scouts and showed 

 that Boy Scouts by no means spend all their spare time. hiking 

 about the country. The articles exhibited included paper 

 knives made of rare native woods, bird houses, bridge models, 

 tabourets, knot boards (illustrating many types of knots tied 

 with cord and rope), camp scenes, and collections of nature 

 material. The attendance at the exhibit was about 600. 



Study Material for Educational Institutions 



The rapidly increasing popularity of this branch of our service 

 is particularly gratifying. During 1924 Miss Charlotte S. Young 

 has continued in charge of this work, which now occupies nearly 

 all her time. During 1924 we received from high schools, 

 academies, colleges, and other educational institutions (mainly 

 in Brooklyn, but some also from other boroughs), 143 requests 

 for plant material of all kinds to supplement and enrich text- 

 book studies. This is a large increase over last year, no, and 

 over the year before, 48. Eleven hundred eighty petri dishes 

 with sterile nutrient agar have been sent out for the study of 

 molds, bacteria, etc., in the schools. This is nearly twice last 

 year's number, 664, and over three times the number sent out 

 in 1922, 358. During 1924, 161,450 pupils used study material 

 of one sort' or another, furnished by us. A tabular outline 

 illustrates the growth of this service more clearly:
