THE EVOLUTION OF A MOTHER. 277

 nature — spring off into independent life the moment 

 they are born ? If the Mother is to be taught to know 

 her progeny, surely the progeny also must be taught 

 not to abandon their Mother. And hence Nature had 

 to set about a somewhat novel task — to teach the

 once more over the Animal series and see how thor-

 for more weeks it remains — not quite so quietly — in 

 the nest ; and for more weeks still — but with an ob- 

 vious itching to be off — in the neighborhood of the 

 nest. This, nevertheless, is a good subject. It is
