They frequently found arrowheads and sometimes other stones, broken, but showing the work of human hands upon them, all of which spoke with certainty of bygone people, but never anything of modern times. Near the lagoon were several low hills, and on these they found the cotton-tree. This tree in its season produces big pods full of silky white cotton, and though the yield is not so very abundant, nor the quality so very fine, yet they saved every pod they could find, Delbert and Esther often climbing up for those that could not be reached from the ground with a pole.

“Some day I will invent a spinning-wheel and a loom,” said Marian, “and we will make cloth.” And the children, remembering the rope-making machine she had made, never doubted her ability.

Once, when they were about two miles from the end of the estero, they found a good-sized tree that had blown down some years before on the side of a little hill. It was larger than any tree growing there now and seemed to have been alone among its dwarfish neighbors. It was too heavy to be dragged all that distance, but if they could manage to chop off the few limbs and the roots that stuck up so high, they could roll it down to the estero and float it home.

It was a big task, but because they had plenty of time on their hands and no pressing social duties, and also because they needed that log in their business, they made trip after trip, starting at daylight and not getting home till nearly dark, chopped and chopped with the hatchet until they had the log smooth enough to roll, and then rolled it over and over all that distance and floated it home in triumph.

Then they set about improving the raft. The new log was a little crooked, but otherwise was about the equal of the one they had captured out in the bay. The three logs together would be much better than the raft as it was. Delbert’s idea was to lash them together as they had been doing, but Marian had thought of an improvement, though it almost seemed as if it could not be done with their limited facilities. They had already accomplished so many tasks that seemed hard, however, and Delbert was such a bright and willing helper, and the little girls were always so willing to contribute their share to any labor, that she told Delbert that at any rate they would have a try at shipbuilding.

CHOPPED AND CHOPPED UNTIL THEY HAD THE LOG SMOOTH ENOUGH TO ROLL

Long and longingly she looked at the old canoe, but in the end left it where it was in the corral fence. She could think of no way to combine it with the logs to make a more serviceable craft.

The new log was rolled up on the beach beside the one they had found out on the water, and then the raft was taken to pieces, and the log in the middle of it was also rolled up on the beach. After they were all fixed in just the right position, they were kept in place by stakes driven into the ground.

The next thing was to make a new tool. Among the scraps of iron found on the little egg island was one about an inch in diameter and nearly three feet long when straightened out. It was round, an immense bolt maybe, but rusted and bent and twisted. What Marian did first was to heat it to straighten it out.
