 sects become so numerous as to work noticeable damage.

 of plant is far more tender under some conditions than 

 others.

The natural enemies of our enemies do much toward 

 keeping them in check. Each larva has its parasite, per-

 parasites until it seems strange the insect world is not 

 entirely destroyed, but because of Nature's most delicate
