LESSON ON THE CHIMNEY SWIFT GIVEN 

 AN EIGHTH GRADE CLASS, 

 SOMERVILLE MASS. 



TO 



M. 



BY 



Eva Warren. 



I gave my class a lesson on the chimney swift using a skeleton 

 nnd skin of the bird and a nest glued in position upon a board. 



I also showed them sketches of the ; glands in the throat from 

 which the glue is exuded, and of the tongue similar to those given 

 below. 



The class later wrote an exercise upon the lesson. The follow- 

 ing paper is one of the set. One of the boys made a creditable 

 painting of the objects used in the lesson. 



The Chimney Swift, By Edward Douglas. Age, 13. 



* He is called a chimney swift because he always lives in a chimney, 

 and because he moves his wings faster than any other bird. He is sometimes 

 called a chimney 'swallow because he somewhat resembles the swallows. 



The chimney swift lives in America. He is one of the latest birds to 

 come, and goes early in the fall. When it leaves in the fall it goes to 

 tropical countries.
