3 2 Coral Sponge. 



55. There are other pretty ornaments made 

 from the skeletons or kind of bony substance 

 of small creatures which have died in the ocean 

 in such large numbers as gradually to form 

 islands. What is that substance ? Coral. 



56. There is another substance, not ornamental 

 like the pearl or coral, but very useful. It looks 

 like a sea plant, but is also the skeletons of what 

 were once living creatures. It is very soft, and 

 it adheres to rocks, shells, etc., under water. 

 Mention it ? Sponge. 



57. For what is sponge useful? (Teachers should show 

 the class a piece of sponge, coral, whalebone.) 



58. I shall now draw on the blackboard the 

 shape of the bottom of the ocean. 



1, the shore; 2, the surface or level of the ocean; 3, the 

 bottom of the ocean. 



How deep do you think the ocean is ? You ? and 

 you? etc. The highest trees (those in California) and 

 church steeples in this country are about 300 feet high. 

 How many of these, one on top of another, would reach 

 from the bottom of the ocean to the top or surface ? Forty.
