and mode of life. Compare the animals as to these struct- 

 ures. Let the children consider both the canine and feline 

 animals together, and make their own grouping of them. 

 Ask them why they put the dog, fox, and wolf together; why 

 they did not put the cat in with this group. Thus bring out 

 both differences and likenesses. Do not make the grouping 

 too scientific, but let it be rather informal. Speak of 

 the dog's wild relations, the wild cats. (F, 34, 33, 32, 25, 

 17, etc.) 



Birds: Interest the children in keeping poultry, doves, 

 etc. Perhaps their parents may be induced to give them 

 ownership rights in some of the poultry at home. Talks 

 about what we get from poultry. How they should be cared 

 for. Show poultry catalogue. Farmers' Bulletins: No. 41 

 on Fowls; 51, Standard Varieties of Fowls; 64, Ducks and 

 Geese; 141, Poultry on the Farm; 177, Squab Raising; 

 200, Turkeys; 128, Eggs. (See Gen. Ref. 246.) 



Also use references: 231, 222, 228, etc. 



Keep children interested in the winter birds.* Have them 

 try to attract and feed them. Read stories about them, how 

 to be kind to them. Put out for them sunflower heads, 

 sheaves of grain, and crumbs. Hang marrow bones and suet 

 to the orchard trees or near the windows where the birds 

 may be seen. (Chap. X, 109, 113, 478, 120, H.) 



Plants. 



Sugar: Notice sweetness of apples, etc. What makes 

 them sweet? Where does our sugar come from? Make 

 study of sugar-cane and the preparation of sugar. Show 

 pictures of the plant, and the stages of preparation. (V,
