THIRTT-FrRST BIENNIAL REPORT 77 



large number of the high schools have been reached with lectures as 

 well as numerous elementary schools. In almost all instances, motion 

 pictures were used to illustrate the lectures. Furthermore, endeavor 

 was made to stir the interest of teachers in wild life conservation and 

 when lectures were given, teachers were asked to follow up and deter- 

 mine how much children had learned. Records also show that most of 

 the teachers' colleges of the state made use of our lecture program. 

 This is a particularly fruitful field in that prospective teachers receive 

 instruction. 



Though a considerable total of lectures were given in the San Fran- 

 cisco Bay region, there was a determined effort to reach mountain 

 counties and out of the way places. Numerous lectures were purposely 

 planned in southern California. Bureau heads have greatly aided in 

 the lecture program. 



Fish and game protection association meetings gave opportunity to 

 discuss problems with sportsmen and service clubs furnished oppor- 

 tunity to meet business men. 



During the spring of 1930, a course on the "Aims, Methods and 

 Materials of Nature Study" was given a group of more than fifty 

 school teachers in Oakland. The demand for this course evidently came 

 as a result of intensive accomplishment b}^ a school lecturer of the 

 bureau a couple of years ago. 



The director of the bureau represented the division at the American 

 Game Conference at New York City, December, 1928, and again in 

 December, 1929. At tbe same time, it was possible to attend meetings 

 of the Committee on Educational Problems in. National Parks. 



Thousands of people were reached through broadcasts over the radio. 

 A special Bird and Arbor Day program was given over radio KGO in 

 March, 1929. During the fall of the same year, a series of broadcasts 

 were given over KKE, participated in by several different employees 

 of the division. Some presentations took the form of dialogues and 

 others were informal talks.

Summer Resort Educational Work. Participation in the educa-

 the work to outlying stations and to the Yosemite Hatchery, where 

 there was splendid opportunity to interest visitors in fish propagation. 

 A new method of instruction was developed in the summer of 1929,
