Harriet. Some of them are white, arid others 

 gray. 



Aunt M. Did you ever see them change their 

 skin ? 



Harriet. Yes, I have seen them several 

 times. The head came out first, and then the 

 body, and one of them died while it was strug-

Aunt M. And how did they spin their co-

Harriet. Father got me a branch of a tree, 

 and two or three little papers rolled up, and one 

 of them then went on the branch, and the two 

 others into the papers. I do not remember much 

 about it, only that the one that was on the branch 

 spun threads of silk from one twig to another, 

 and then spun silk round and round itself, until 

 it was entirely wrapped up in it, and looked 

 like a beautiful little yellow egg. The two other 

 cocoons were white. 



Aunt M. That is a very good description ; 

 but what about the moths that came out of the 

 cocoons ?
