We are glad, too, that the dragon flies have their pretty, swift wings.
They have four wings, all nearly the same size and shape, you see, and
they are all stiff and shining.
Some dragon flies, like this one we have picked up, always keep their
wings spread out.

But over there, standing on the end of that stick, is another kind.
When it rests its wings are folded together.
What a pretty one it is! Do you see it?
It is small, but so pretty.
It is bright blue and shines as though it had been polished.
Sometimes birds catch these smaller dragon flies, though birds, as a
rule, are not fond of any of them.
They are so hard and their wings are so stiff I should think a bird
might almost as well swallow nails.
