SEAWORMS, SEAWEEDS. AND OTHER 

 SEA-THINGS. 



ERE we are, all together once more. 

 And now, Mary, we will look at 

 your wonderful jar. It may prove 

 to be a vase full of real treasures. 

 And first, tell me why you put 

 pieces of seaweed in the water. 

 I have heard that sea-plants help to purify the 



water for the animals that live in it. 

 You are right, though a 



little piece in a jar cannot 



do very much good. But 



in an aquarium, where you 



keep living animals, it is 



necessary to have a good 



number of growing plants 



to supply oxygen. Please 



show me what plants you 



have in your jar. 



Thank you. This smooth 



green one looking some- 

 what like a fresh leaf of
