Sometime you may find these cast-off dragon fly overcoats.

After it has shed its skin the dragon fly continues to grow. It keeps on
growing until it has outgrown its new skin.

Then what do you think it does?

Yes, Charlie, that is right, it sheds this skin too.

[Illustration]

When it sheds its skin we say it moults.

It moults several times, and at last little short wings appear. At first
it has no wings at all, you know.

Amy wonders how the larva breathes under water.

Ah, Master Ned, you are laughing too soon. You think insects do not have
to breathe, but you are very much mistaken, sir.

Insects do have to breathe.

They would die if they could get no air to breathe.

Some of the dragon fly larvæ have an odd arrangement for breathing under
water. They have a sort of syringe in the end of the body, and there are
breathing pores or gills in the syringe.
