The stream just opposite their home was deep and quiet, but a little way below, the current ran strong; and once, having ridden down it gaily for a couple of hundred yards, they found themselves unable to swim back against it.

At first they battled bravely and were most surprised to find themselves making so little progress.

Then they grew tired; and then frightened, and they were just being carried off down stream by this strange, soft, irresistible force when their mother arrived.

The current was nothing to her.

She took them on her back, and shot off up stream again with them.
