watched the caddises eating dead sticks as greedily as you would
eat plum-pudding, and building their houses with silk and glue.
Very fanciful ladies they were; none of them would keep to the same
materials for a day. One would begin with some pebbles; then she
would stick on a piece of green wood; then she found a shell, and
stuck it on too; and the poor shell was alive, and did not like at
all being taken to build houses with: but the caddis did not let
him have any voice in the matter, being rude and selfish, as vain
people are apt to be; then she stuck on a piece of rotten wood,
then a very smart pink stone, and so on, till she was patched all

times as long as herself, and said, "Hurrah! my sister has a tail,
and I'll have one too;" and she stuck it on her back, and marched
about with it quite proud, though it was very inconvenient indeed.
And, at that, tails became all the fashion among the caddis-baits
in that pool, as they were at the end of the Long Pond last May,
and they all toddled about with long straws sticking out behind,
getting between each other's legs, and tumbling over each other,
and looking so ridiculous, that Tom laughed at them till he cried,
as we did. But they were quite right, you know; for people must
always follow the fashion, even if it be spoon-bonnets.

Then sometimes he came to a deep still reach; and there he saw the
water-forests. They would have looked to you only little weeds:
but Tom, you must remember, was so little that everything looked a
hundred times as big to him as it does to you, just as things do to
a minnow, who sees and catches the little water-creatures which you
can only see in a microscope.

And in the water-forest he saw the water-monkeys and water-
