This is a story of how some furry pioneers found a quiet place in 

 the Canadian woods and decided to settle down and keep house 

 there. A little brook ran out of one of the clearest and cleanest 

 lakes you ever saw. Along its banks grew poplar trees and birches, 

 both soft wood; and as their teeth serve these pioneers for saw 

 and axe, soft wood is the best kind for them to use. In the hot 

 summer months when the lakes get low their outlets get lower and 

 sometimes dry up ; that is one reason why the dams are called for ; 

 another reason comes with the cold winters, when little streams 

 are frozen to the bottom and animals who live a large part of their 

 lives in the water find this rather inconvenient. By building a 

 dam, you see, they raise the level of the water so high that it cannot 

 freeze to the bottom even when the mercury is forty below zero. 

 Here, then, was a secluded place, off the beaten track of tourist 

 and hunter. Tall cliffs rose a little distance from the stream, and 

 everywhere were woods of birch and evergreen. 



The beaver is a funny fellow. Imagine a woodchuck about the 

 size of a half-grown collie dog, with a wide, flat tail covered with
