A GROUP OF SAND-DWELLERS. 



VERYBODY knows that olives grow on 

 trees, and that they are used for making 

 oil and also for pickling. They 

 are small, smooth, oval fruits, 



^\7 -7^- and are green at first, but be- 

 : come purple when they ripen. 

 But perhaps there are many 

 people who do not know that there are many ocean 

 shells that are also called Olives. And they are 

 called so because they, too, are small and smooth 

 and of an olive shape. As to their color, they are 

 never green, but some of them are purple, and 

 almost all of them are very pretty. 



The little animal that 

 lives in these shells loves 

 to burrow in the sand, 

 not very far down, but just 

 deep enough to cover the 

 shell, while a pipe thrust 

 up through the sand sup- 

 plies the creature with wa- 

 ter for its gills.
