WAYS OF NATURE 



when our yellow warbler, finding this strange egg of 

 the cowbird in her nest, proceeds to bury it by put 

 ting another bottom in the nest and carrying up the 

 sides to correspond, she shows something very much 

 like sense and judgment, though of a clumsy kind. 

 How much simpler and easier it would be to throw

 desperately to satisfy the hunger of her big clam 

 orous bantling of a cowbird, never suspecting that 

 she has been imposed upon !

 orders is not a straight line. It has many breaks and 

 curves and deep indentations. The man-like apes, 

 as it were, mark where the line rises up into the 

 domain of man. Furthermore, the elephant and the 

 dog, especially as we know them in domestication, 

 encroach upon man s territory. 



Men are born with aptitudes for different things, 

 but the art and the science of them all they have to

 The animal inherits its knowledge and its skill : man 

 must acquire his by individual effort ; all he inherits
