go of the shell, and scrambles away from the 

 dangerous place as rapidly as possible. 



In the little tide-pools you can often find great 

 numbers of hermit crabs in their borrowed shells. 

 Some of them are very small, and live in shells 

 not more than half an inch long. It is very in- 

 teresting to throw them some bits of fresh meat 

 and see them scramble for it. 



The hermit crabs are great shell-hunters, as 

 you might suppose, and by means of their aid you 

 are sometimes able to obtain the shells of mol- 

 lusks that usually live in deeper water. 



Some people who see the crabs in their shells 

 think that they are the creatures which made the 

 shells; but we know better, don't we? 



Always keep your eyes open, and think about 

 what you see. In this way you will gain the habit 

 of observing, which will be very useful to you 

 throughout your whole life.
