you some idea of what power man has in his 

 hands by selection. 



A man wishes to breed a dog say for special 

 speed. He has a litter of puppies ; he then 

 selects and rears only those puppies or that puppy 

 of the litter which looks like being a bit faster 

 than the others. 



These selected puppies have in their turn 

 puppies, and again he selects and rears only those 

 puppies of the litter that look like being a bit 

 faster than the others. In this manner he goes 

 on selecting, rearing, breeding, generation after 

 generation, till at last he breeds the greyhound 

 that wins the Waterloo Cup. 



Another man thinks he would like to breed 

 a very strong and massive dog. He also has a 

 litter of puppies, and he also selects and rears 

 only those puppies that look like being, 'not a bit 

 faster, but a bit the stronger, more massive than 

 the others. 



These selected strong puppies have in their 

 turn puppies, and again he selects and rears only 

 those that look like being a bit stronger than 

 the others, and so generation after generation 

 he goes on selecting and rearing in the direction of 

 power and strength till at last he breeds a powerful 

 mastiff that can pull a man to the ground. 



From very much the same original stock see 

 what a variety of dogs man has bred.
