 it in this place ; for it is rapidly assuming the importance of a 

 first class pest. This, however, is unnecessary as it is one of the 

 easiest of insects to combat. 



We have two very common insects that build their webs in fruit 

 and forests trees. One of these makes its webs early in the spring

 trees ; frequently occurring in large numbers upon ash, oak, and 

 other forest trees, as well as fruit trees. The former of these is 

 the Apple-tree Tent-caterpillar {Clisiocampa amcricand) ; the 

 latter, the Fall Web-worm {Hyphantria ctined) I do not care to

 with it. 



The accompanying figure illustrates the transformations of the 

 Apple-tree Tent-caterpillar. The eggs are shown at c ; these are 

 laid in a ring-like cluster about a small twig, and are covered 

 with a substance, which protects them from the weather. These
