"But not without tools," says Billy.

However, he agreed to my proposal, and we carried a rock between us, with a great deal of sweating, up to where the fallen trees lay, and then Billy says, "Ain't we fools!" and showed me that we could save a deal of labour by fastening strands of creeper to the second rock, and dragging it up instead of carrying it in our arms. This being done we cut two stout poles, which took us a long time, and then, putting the rocks one on either side of the first trunk, we took a pole each, and, resting them on the rocks, put the one end under the tree and pressed heavily on the other, and so contrived to lift the weight which our unaided strength was quite unequal to. I do not mean that we had never seen levers before, but we might never have thought of them unless Billy had prised up the rock after that crab. The use of levers was indeed a mystery to him, I mean the explanation of them, he saying that we were no stronger than before, and there was certainly no strength in two dead poles, and when I reminded him of the pulleys and the windlass on board ship, which also helped to raise things, he said that poles were not pulleys, nor a windlass neither, and he didn't see what that had to do with it. However, there was the trunk lifted, and while I held it so with my pole, Billy slipped a roller under it, and working thus from the end towards the middle, we brought the roller along by degrees, and then found that we could slip the second roller under the other end without the help of the poles.

Then, with much pushing and hauling, we set the trunk a-moving on the rollers down the slope. It was still hard work enough, for where the earth was soft, the rollers sank into it under the heavy weight of the tree, and when we came to a part that was hard and pretty smooth, the trunk set to a-rolling so fast that it almost ran away with us, and Billy, who was in front, was very nearly sent headlong down, which would have been very terrible if he had fallen plump into our grate. We brought the other three trunks down to our plateau in the same way, and thus had the four stout posts which we intended for the corners of our house, though there was a great deal to be done to them before they could be erected. They were about the same thickness, being sixteen or eighteen inches across, but not the same length, and we had first to make them equal, which took us a long time; I think we were ten days at the work. When we had finished it, the trunks were about fourteen feet long, that being the height we had determined on for our house, allowing for some portion of the posts to be driven into the earth. We did not peel the bark off the trees, but left it on, thinking it would do no harm.

Choosing a Site

We marked out the lines of our house, on the level plateau near the lake, which was almost the only even spot on the island, and allowed us a space of about twenty feet square, which I thought was large enough, thinking besides of the great labour we should be put to if we tried to make too big a house. But when it came to erecting our corner-posts we were in a great quandary. The ground was pretty soft, and deeper than at other parts of the island, which I guessed was due to the heavy rains washing earth down from the hill above. With spades or shovels we might have dug holes to a considerable depth, and then slipped the trunks in, and having thus disposed of a part of the dead weight of them, we might have raised them to an erect position with levers, or by pushing them up with our hands as men raise a long ladder. But with no tools save our blunt axes we saw that such excavation would demand unconscionable toil, and besides, after we should have accomplished it, we should be hard put to it to make the earth around the timber sufficiently firm and compact; so we had to consider another way, which gave us a great deal of trouble. Indeed, it baffled us for several days, in which, however, we were not idle, but occupied ourselves in other concerns.

A Flagstaff

One of these was the erecting of a signal-post. Although, when we talked matters over—as we often did, both in the daytime and especially at night before we fell asleep—when we talked things over, I say, we always concluded that there was little or no chance of being rescued, and made our plans as if we were to remain on this island for the rest of our lives; yet we thought it right to take our measures for attracting any friendly ship that might heave in sight. We must not, of course, attempt to raise any permanent signal, for such a thing would beyond question be discovered by the savages of some neighbouring island when going about in their canoes, and the last thing we could wish was to bring savages into our peaceful domain. On the other hand, unless we had some means of signalling, a ship might easily pass us by before we could communicate with it, for the island was so small that no vessel would heave to on the mere chance of finding water, since its most important river, if it had one, could not be more than a mere brook in size. Being thus decided that we ought to have some kind of signal ready, in such a case, we determined that nothing could be better than a flagstaff, even if we should never have a flag.

As for the spot where to erect it, we had no difficulty in choosing that; no better could be found than the wooded hill above the lava bed, whither we climbed every morning and evening to take our lookout. At the top of this hill, and somewhat apart from the rest of the trees, there stood a tree very straight and tall, overtopping the others, so that it formed a very clear mark. Since our flagstaff was not to be permanently in sight, it seemed best that we should have one that we could take to pieces, and put together when it was necessary to hoist it, and I had already seen, at the edge of the lake, what I thought would serve our purpose to a marvel. This was a cluster of trees, or rather shrubs, like what is called bamboo, the stalks being tough and hollow, with joints or knuckles here and there. We cut down three or four of these stalks, choosing them all of different diameters, and having burnt out the pith inside them, for some distance from the top, we contrived to make a kind of telescope tube by fitting them together, it reaching a length of near thirty feet.

This being made, we cut, in the top of the trunk of the tall, straight tree before mentioned, a groove large enough to form a socket for the bottom end of our flagstaff, and when we had fitted it to our satisfaction, we ventured just before sunset to raise the staff, and it made a sort of topmast to the tree, standing some twelve feet above the summit.

"This is prime," says Billy. "Now all we want is an ancient or a pendant to fix to the top of it, and there you are."
