SOLITARY NESTS. 
caterpillars are hard at work too, and we will 
take a peep at what they are doing. 
There is a caterpillar* on the leaf of the lilac 
tree. How busy it is! We may go close up 
wdthout fear of disturbing it, so intent is it on 
what it is about. It belongs to the ’ solitary 
species, and is going to make a snug little cell, 
where it may live all by itself. It will begin by 
joining the edges of the leaf together, and this is 
no easy matter, for it has no fingers to work 
with, and the leaf is very elastic, and apt to 
spring back again. But the caterpillar knows how 
Leaves rolled. 
* Tinea and tortrix, are leaf-rollers.
