Although the common rabbit is more or less soli- 

 tary, it will (like the Beaver which slaps the water 

 violently with its tail when danger approaches) warn 

 the rest of the rabbits of approaching danger, by 

 thumping the ground with its hind feet. The common 

 deer will likewise raise its tail and flash the white un- 

 der side as a warning to other deer that might be in 

 the neighborhood when it hurries away from apparent 

 danger. The loud screams of many forms, which live 

 in close proximinity, serve the same purpose. 



In every situation there are always a number of 

 kinds of animals. There are then involved, relation- 

 ships among animals of different species. Occasionally, 

 this relationship, between two or more different species, 

 is a symbiotic one; that is, these species live in a part- 

 nership that benefits both or all kinds. When different 

 kinds of animals live in the same region, there is 

 always a series of antagonistic groups which usually 

 narrow down to relationships in which only one mem- 

 ber of an association benefits. This results in a para- 

 sitic relationship, or, in a relationship between preda- 

 tor and prey, the one killing and feeding upon the 

 other. Minks, weasels, otters, raccoons, bears, skunks, 

 wildcats, shrews and foxes are predators and their prey 

 consists of rats, mice, birds, squirrels and many other 

 smaller animals. In nearly all predatory groups, the 

 predators will feed upon each other, when the oppor- 

 tunity to do so presents itself. 



It is certain that "everything has its Satan" and, 

 likew^ise, every animal has its enemies. Sometimes 

 there are certain animals that limit their diet to one
