system. This kind of insect has a mouth fitted to do this work.
Grasshoppers and caterpillars are of this sort. The other kind sucks the
juices from a plant. This, in some ways, is the worst sort. Plant lice
belong here, as do mosquitoes, which prey on us. All the scale insects
fasten themselves on plants, and suck out the life of the plants.

"Now can we fight these chaps? The gnawing fellows may be caught with
poison sprayed upon plants, which they take into their bodies with the
plant. The Bordeaux mixture which Peter used is a poison sprayed upon
plants for this purpose. So, too, is Paris green.

"In the other case the only thing is to attack the insect direct. So

"Lime, soot, and sand are other means of blocking and choking off
insects.

"Sometimes we are much troubled with underground insects at work. You
