1 6S Instinct, 



itself and the tree, so that its branch may fall to the 

 earth, where it goes through its transformations. 

 All the thousands do exactly the same things, as 

 all previous generations have done before them. 



The Apple-tree Borer deposits her ^g^ in the 

 bark and there leaves it. The Borer mines in the 

 wood, feeding and growing for months. But be- 

 fore the time of transformation, it prepares its hole, 

 so that it can easily escape into a world, where it 

 has never been, and from which, up to that time, 

 it has tried to escape. It has never seen the outer 

 world nor known a parent's care, nor one of its 

 kind ; but it comes forth fitted for its work, not only 

 by structure but by Instinct to guide, — to guide it 

 perfectly, in entirely new relations to the world, and 

 in the use of organs it never before possessed. 

 The being bursts into life with nothing to learn, 

 fully prepared to act its part, — and it is absolutely 

 necessary that it should be thus provided for ; be- 

 cause it has neither the time nor the conditions for 

 obtaining its needful knowledge, as intelligent be- 

 ings must obtain theirs. 



It is plain, from these cases and the hundreds 

 like them, which might be cited, that animals come 

 into the world with all their instinctive capacities 

 ready for action, the instant they are needed. And 

 this instinctive outfit, being essential at once to the 

 continuance of life, could not have been acquired by 

 any changes resulting from experience or observa- 

 tion, by themselves or their ancestors. 



The instinct of the young is supplemented, in 

 many cases, it is true, by the instinct of the parent.
