LESSON III 

 THE WEATHER A CAUSE FOR CLOTHING 



What changes shall we soon make in our clothing? Dis- 

 cuss winter clothing: cotton and woolen clothing, under- 

 wear, overcoats, rubbers, overshoes, umbrellas, storm coats, 

 etc., and the conditions which make them necessary. In like 

 manner discuss summer clothing: straw hats, linen coats, 

 suits, etc., white, thin dresses, parasols, fans, etc., and con- 

 ditions which make them necessary. 



Discuss also such animal coverings as undergo change in 

 accordance with the weather. When is the wool cut from 

 the sheep? What change takes place in the hair of a dog, 

 cat, horse, cow, etc., in the fall? in the spring? Why? 

 Do any animals change the color of their coat at the same 

 time? Can you think of any reason for this? Do birds 

 change their feathers? Show the pupils the warm, downy 

 feathers that grow near the skin of many fowls to keep them 

 warm in winter. Tell them about the eider duck and the 

 down procured in Iceland and other cold places. 



LESSON IV 

 ANIMAL SHELTERS 



Describe a model stable and the winter care given a 

 horse. Compare with a henhouse, and note the arrange- 

 ments for the needs of their respective occupants. What 

 would be the result if the horse were turned into the 

 pasture and the chickens allowed to roost in the trees all 

 winter? Why are these shelters necessary for our useful 

 animals ?
