Part 1, Set 3 A — Our Forests and Their Uses — Forests and 



Methods of Lumbering 

 Part 2, Set 3B — Forest Uses and Products — Forest Protection 



and Conservation. 

 There are 27 prepared lectures, and as several of these have 

 been duplicated to meet the needs of teachers, the total number of 

 sets in circulation is 39. 



The complete statistics of the Loans of Lantern Slides will be 

 found in Appendix D. 



Work for the blind, supported by the Jonathan Thorne Memorial 



Fund, has included science talks for the sight conservation classes 



of the public schools, an evening lecture for the 



education adult blind, and loans to classes of natural history 



for the specimens and of relief globes. 



BLEVD Although the talks for the sight conservation 



classes were planned for both spring and fall, the 



spring course was suspended on account of the absence of Miss 



Thomas. In the fall, the work was taken up by Miss Ruth E. 



Crosby, and, in consultation with Miss Moscrip, Inspector of Classes 



for the Blind in the Public Schools, a course of ten subjects was 



arranged, including: 



The Narrative of the World War Miss Fisher 



The Sources of War Materials Dr. Fisher 



How the Eskimo Live Miss Crosby 



Hiawatha's People Miss Crosby 



The Earth and Neighbor Worlds Dr. Fisher 



The Change of Seasons Dr. Fisher 



The Three Forms of Water Miss Fisher 



The Story of the Seashore Miss Crosby 



Where Furs Come From Dr. Fisher 



How Seeds Are Scattered Miss Crosby 



From this list, each teacher chose the subjects she wished her 

 class to hear and the date on which she could most conveniently visit 

 the Museum. Each class was instructed separately and the carfares 

 of the pupils and guides were refunded when desired. The chief aim 

 in giving these talks is to provide the pupils with adequate material 

 which they can "see with their hands." In this way they gain a clear 

 impression of many things which are difficult to describe and which 

 are often wrongly conceived. For instance, the talk on the World 

 War is illustrated by a large relief model showing the trenches and 

 dugouts of a modern battlefield. A class of wide-awake high school 

 girls, when shown this model, was amazed to find that a trench was 

 hollowed from the ground. Without exception, each girl had had the 

 impression that a trench was but a mound of earth like a hill.
