Zoology. 374 THE WORLD OF ANIMAL LIFE rocket ascends into the air because, when it is fired, a great quantity of gas rushes out from it, and pushes against the air with such force that the rocket is driven upwards.

The result is, that it pushes against the surrounding water, just as the gas from the rocket pushes against the surrounding air. The insect grub is thus driven sharply forwards. THE EARWIG (Family FORFICULID^) The Earwig is not the dangerous insect we have imagined it to be. It has no desire to enter our ears, nor are its tail-pincers alarming, as their chief use is said to be the folding up of its wings. An earwig's wings are large, but the covers under which they have to be packed, when they are not being used, are small. So the earwig, as soon as it settles, turns its tail up over its back, takes hold of one of its wings with its pincers, and folds it neatly across. Then it folds it again, and again, and again, until it is small enough to go under the wing-cover. Having done this, it treats the other wing in the same manner, and packs both wings away in a very few seconds. The earwig is almost the only insect that takes any care of its eggs. If you turn over a big stone in the early spring, you may sometimes find an earwig standing closely over its pile of little white eggs. It does not attempt to hatch them by the warmth.
