. They waded out and
pulled them in toward shore.

"Let's ride on these the way we rode that log in the river," said
Firetop.

Firefly was always ready to do whatever Firetop did, so she got astride
one, and Firetop mounted the other, and they went bouncing along through
the water, half floating and half walking on the sandy bottom.

It was great fun, but the long branches stuck in the sand and scratched
their legs, so they drew the logs nearer shore and tried to pull off the
branches. But some of them were too tough.

"We can twist them together," said Firetop. "That will keep them out of
the way and maybe the logs won't roll so much."

They twisted the branches of the two logs roughly together, so they
could not stick down into the water and then mounted their sea horses
again and rode away. They were delighted to find that now the logs
behaved much better, and they grew so bold that they ventured out into
deeper water. They had made a wonderful plaything.

All the morning they rode the logs, and when the tide began to come in,
they had the best time of all. It picked up the little raft and floated
the children, screaming with joy, far up the beach on a long, low,
rolling wave.

Limberleg had been so busy making a frame of sticks to stretch the
deer-skin on that she had paid no attention to the Twins. But when she
heard their screams, she came to the door of the cave and looked out on
the beach. When she saw what they were doing, she came running down the
bluff. She ran so fast she was all out of breath, but she gasped out:
"You naughty, careless children! You must not do that any more--ever!
You will certainly be eaten up by a big fish--or get drowned--or maybe
both--if you do!" The Twins thought that their mother was very foolish,
and, being cave twins, and not knowing any better, they said: "Aw,
mother, we have been doing it all the morning, and never got drowned or
eaten up once! Try it yourself and just see how easy it is."

But Limberleg was very unreasonable. She only said, "If you do it
again, you know what will happen," and started back up the bluff. When
she was out of sight, Firetop said: "Let's do it once more. She won't
see us!" This shows just how wicked and disobedient cave children could
be!

They pushed their raft out into the water and got on board. They were
at the very farthest point from shore, when suddenly Limberleg came
right out of the bushes and looked at them! Wh
