THIRD GRADE WINTER WORK 149 



In this way cause the pupils to see that insects must have 

 a different way of passing the winter than the animals hereto- 

 fore studied. If not too late, some caterpillars may be found 

 and placed where the children can see them make their co- 

 coons : possibly in the spring the children may discover them 

 hatching out as perfect insects. 



NOTE. From actual observation during the year the pupils should 

 learn the various stages in the cycle of insect life. Use good pictures 

 when the real object cannot be seen, but never otherwise. 



A special study of the silkworm should be made in this 

 connection, and, if possible, a visit be made to a silk factory. 

 Many pictures of the silk industry can be obtained easily, 

 and, where practicable, a colony of silkworms should be raised 

 in or near the school in the summer. It is a very profitable 

 industry, and its processes are simple, yet very interesting. 



LESSON XXIV 

 ANIMAL COVERINGS 



Name the different kinds of coverings that animals have to 

 protect themselves. Make the list as complete as possible. 

 It may include feathers, fur, hair, wool, bristles, spines, scales, 

 shells, skin, etc. Each of these coverings may form the sub- 

 ject of one or more lessons. Only a few can be discussed 

 here in detail. 



Have the pupils bring samples of as many different kinds 

 and sizes of feathers as they can get. Have them tell from 

 what bird each came. 



Where are the largest feathers on the bird found ? What 

 is their chief use? What is the chief use of the smaller
