Fortunately, after a while, Corny went to sleep.

We were very glad of it, though how she managed to sleep while the raft was rising and falling and sliding and sloshing from one wave to another, I can't tell.

But she didn't have much holding on to do.

We did that for her.
At last daylight came, and then we began to look about in good earnest.
We saw a top-sail off on the horizon, but it was too far for our raft to be seen from it, and it might be coming our way or it might not.

When we were down in the trough of the waves we could see nothing, and no one could have seen us.
