38 NATURE STUDY LESSONS FOR PRIMARY GRADES 



tell how you think the sheep gets its cud ? [Chil- 

 dren review process of rumination in the cow. If 

 this study is taken up in the winter time, the children 

 observe the sheep eating hay instead of grass.] 



Which eats the grass off the shorter, the cow or 

 the sheep ? Why can the sheep do this ? 



Does the sheep eat corn in the same way that a 

 cow eats it? [Children name any differences that 

 they may have observed.] (A sheep nibbles off the 

 kernels.) Watch it and see how it does this. What 

 else does it eat? Does it eat carrots, turnips, and 

 beets, as a cow eats them ? What difference ? Does 

 it hold the food down with its foot, as the dog some- 

 times does, when eating its food? How do sheep 

 eat salt ? How drink water ? 



Notice how lightly the sheep step about. Let us 

 look at their little feet. What do you find ? (They, 

 like the cow, walk on their toe nails — two on each 

 foot.) 



Did you ever think how much the cow and the 

 sheep are alike ? They surely must be cousins. 

 Name those points in which they are alike. 



(a) Both have cloven hoofs (walk on toe nails). 



(b) Both lack teeth in front part of the upper jaw. 



(c) Both chew the cud.
