HASTY OBSEKVATION 255

 marshes in May to deposit its eggs. The common 

 bullfrog and the pickerel frog doubtless pass the 

 ■winter in the bed of ponds and streams. I think 

 it is quite certain that hibernating animals in the 

 ground do not freeze, though by no means beyond 

 the reach of frost. The frogs, ants, and crickets are 

 probably protected by some sort of acid which their 

 bodies secrete, though this is only a guess of my 

 own. The frog I dug out of the leaves one spring 

 day, while the ground above and below him was

 joints were apparently very stiff. A friend of mine

 ants out of a piae log in winter, and though appar- 

 ently lifeless, they are not frozen. 



There is something in most of us that welcomes 

 a departure from the ordinary routine of natural 

 causes; we like to believe that the impossible hap- 

 pens; we like to see the marvelous and mysterious 

 crop out of ordinary occurrences. We like to be-

 can exert some mysterious influence over bird or 

 beast at a distance of many feet, which deprives it 

 of power to escape. But there is probably little

 and doubtless this is the whole secret of the power 

 of snakes and cats to charm their prey. It is what
