I had often crossed it on a log; but behold, when I got there no log was to be seen.
"I know'd of an island in the slough, and a sapling stood on it close to the side of that log, which was now entirely under water.

I know'd further, that the water was about eight or ten feet deep under the log, and I judged it to be three feet deep over it.

After studying a little what I should do, I determined to cut a forked sapling, which stood near me, so as to lodge it against the one that stood on the island.

In this I succeeded very well.

I then cut me a pole, and then crawled along on my sapling till I got to the one it was lodged against, which was about six feet above the water.
"I then felt about with the pole till I found the log, which was just about as deep under the water as I had judged.
