THE ARRIVAL OF THE FIT

 scious expression in the brain of man, is just as man- 

 ifest in all the forms of animals and plants that are 

 inimical to him, in all his natural enemies, ven- 

 omous snakes and beasts of prey, and insect pests,

 powers that she has denied him. Evidently man is 

 only one of .the cards in her pack; doubtless the 

 highest one, but the game is not played for him

 parts. The universe is not run on modern business- 

 efficiency principles. There is no question of time, 

 or of profit, of solvency or insolvency. The profit- 

 and-loss account in the long run always balances.

 some future period. 



There is economy of effort in the individual or- 

 ganism, but not in the organic series, at least from 

 the human point of view. During the biologic ages 

 there have been a vast number of animal forms, 

 great and small, and are still, that had no relation to
