THE SHEEP 39 



Are they unlike in any ways ? Look at the two as 

 they graze side by side. How can you tell them 

 apart? (The cow is much larger than the sheep. 

 The sheep could run under the cow. The sheep is 

 nearer the size of the shepherd dog.) 



If both were of the same size, could you tell them 

 apart by their looks ? (The sheep has a wool coat, 

 the cow a hair coat.) Is there any other difference 

 in these coats, except that one is wool and the other 

 hair ? (The sheep's coat is usually white occasion- 

 ally brown ; the cow's coat may be white, red, black, 

 or spotted.) Is there not still another difference 

 between the sheep's coat and that of the cow ? (The 

 sheep's wool coat is much thicker than the cow's 

 hair coat.) Let us look closely at this wool coat. 

 Have wool in the class. Each child may pick some 

 to pieces and see if it is at all like the cow's hair 

 coat. (It is hair, only the hairs are much finer than 

 those of the cow, and they are wavy and seem to 

 be fastened together, so that it is hard to pull them 

 apart.) Stretch one of these fine hairs. What about 

 its length now ? (It is much longer than it looks to 

 be when on the sheep.) Does the wool lie down on 

 the sheep's body in the same way that the hair lies 

 down on the cow's body ?
