When her eggs hatched, the larvæ were slender, soft, six-footed babies called Caddis Worms. They were white, and they showed as plainly in the water as a pond-lily does on the top of it. It is not safe to be white if one is to live in the water; certainly not unless one can swim fast and turn quickly. And there is a reason for this, as any one of the pond people will tell you. Even the fishes wear all their white on the under side of their bodies, so that if they swim near the top of the water, a hungry Fish Hawk is not so likely to see them and pounce down on them.
