As soon as they got their wings, away went those dragon flies,--away
and away, without stopping to catch a single mosquito for the men who
had taken the trouble to raise them.

The dragon flies will not stay at home.

They fly so fast and so far there is no use raising them.

They are among the swiftest and strongest of insects.

How do the larvæ get in the ponds? Frank is asking.

I will tell you what I know about it.

[Illustration]

The winged dragon flies mate, and the female then drops her eggs in the
water or lays them on twigs in the water, where they hatch out into
larvæ.

The dragon flies have to be very careful when they go close to the water
to lay their eggs.

You all know why.

Yes, it is because the frogs are on the watch to catch them.
