CATERPILLARS. 99 



ration of the caterpillar from the inside of it, it is 

 wonderful how the junction of the new with the 

 old bark was effected with the extreme nicety with 

 which it is seen, and also how the case was closed 

 up when nearly completed. 



In another instance, a caterpillar of the same 

 species of moth made its case on some old paling, 

 and the colour of the wood was completely imi- 

 tated. I consider these as amongst the most 

 curious specimens of insect architecture, I have 

 met with, and they aiford proofs of the instinct 

 implanted by a benevolent Creator in insignificant 

 insects for their preservation. No wet can pene- 

 trate, and no bird could discover, or get at the 

 imbedded cocoon. I can only regret the difficulty 

 of giving an adequate idea of this curious structure. 



I may also mention another interesting fact 

 relating to moths. It is that they invariably, 

 I believe, turn into cocoons on the south or warm 

 side of trees, and never on the north sides. 



It is always pleasing to watch the first emanci- 

 pation of butterflies, and moths from their wintery 

 cells on a balmy day in spring. Every thing then 

 is so fresh, so joyous and delightful. These pretty 

 insects settle on the newly-expanded flower, and 

 flit about in the sunshine, or hover in the calm and 

 tranquil evening beneath a spreading oak. It is 

 then we may be reminded of that beautiful and 

 allegorical description of the Spring, in the Song 

 of Solomon
