 sure that the species do not fail. 



How clever, too, they are about their food! They 

 have to be or else starve. No doubt many of them 

 have starved in the past, and only the clever ones 

 survived and so continued the species. When one 

 sees the birds in spring scouring about for food

 mice and squirrels and foxes in the barren, desolate, 

 snow-choked woods, or of the thousands of crows in 

 winter going to and fro night and morning in quest 

 of forage, one realizes how acute and active and

 I do not know, but he rarely fails. I am sure that I 

 could not pick out the spots. But my dinner is not 

 contingent upon that kind of acuteness; if it were, 

 no doubt I could quickly learn the secret, too. The
