However, I was beginning to tell of the notion that came into my head as we lay that evening above the lake. Being so little distant from it, I thought, why should we not sink a well in the floor of the hut, and connect it with the lake by a pipe?
"What's the good?" says Billy, when I put the question to him. "For one thing, the water won't run up into the hut without a pump; at least, I've never seen water run uphill yet; and then, as soon as any savages come, you may be sure they'll spy it, and then where are you?"
I said that as for the latter point, we should, of course, take care to show no sign outside of what we had done; and as for the former, I did not despair of finding some way to raise the water to our level, even if we could not make a pump. Billy talked till it was dark about the difficulties of what I proposed—the difficulty of digging a hole, of preventing the earth from falling in, and so forth—until you would have thought he was the poorest-spirited creature that ever lived; but that was only Billy's way, and I often observed that he was never so active and eager, aye, and never so hopeful too, as after he had been talking in this gloomy manner. At any rate, next day he set to work with me to make a trial of my notion.
It happened that, the weather having been dry for a good while, the water was now low, indeed, within a foot of the lowest point to which we had ever known it to sink, which was favourable to our plan; for it was necessary that our pipe should enter the lake below the water's surface, even in the driest weather, and moreover if the latter had been full, we should have found it very troublesome, and perhaps impossible, to do as I shall now relate. This was nothing less than to dam up the water of the lake for a little space, so that we might cut a passage through the side of it towards our hut. To make this dam we felled a number of logs and dragged them down to the bed of the lake, where we arranged them in the shape of a great V, the point of the V being out in the lake, the ends resting on the shore. We lashed the logs together very firmly, and coated them with clay, and so made a dam which we found to answer very well. Of course we had to bale out the water which was first between the arms of the V, and Billy grumbled as we did this, saying that he was sure there would be a heavy rainstorm, and all our work would be for nothing; but in this he turned out a false prophet, since we had no rain at all for many days.
When the inside of the V was dry, its floor was about three feet below the level of the water outside of it; and within that dry space we could work very comfortably at making a cutting through the bank towards the hut. To do this we had to make spades, which we fashioned out of hard wood as well as we could with our axes, and they served our purpose excellently well, though they would not have done so had not the earth been soft; if it had been rocky, I know not what we should have done. With these spades we began to cut away a portion of the sloping bank of the lake, continuing till we had, as it were, taken a slice or a wedge off it, up to within about three yards of our hut. This took us two whole days, for the earth, though soft compared with rock, was pretty compact, and our clumsy tools made us sigh often, and sweat too.
Having come, as I say, to within ten feet or so of our hut, I thought we might then give over digging and endeavour to pierce a way to a point directly beneath the centre of the floor, or at least near enough as that we might sink a shaft to meet it. We surveyed the position for some little while, so as to take our bearings, as Billy said: and then, having got a pretty good notion of the course our proposed passage should take, we shoved into the earth, horizontally, a pole we had sharpened to a point, and when we found we could push it in no further, we drew it out and gave it another mighty shove, directing it in such a way as we thought would bring it midway between the two corner posts, though of course several feet below the floor. We found after a time that, though we tried to drive the pole straight, nevertheless it deflected somewhat towards the right; and when we pulled it out to give it another shove, it met with some obstacle, which I was afraid might be the bottom part of one of our posts, though I could not conceive how we had gone so far out of our reckoning. But with a little more pushing the pole, being in a certain degree flexible, went past the obstacle, so that if this was one of the posts, it had not been met squarely in the middle. The pole being now wholly in the earth except just enough of it to hold by, we judged that we had driven it as far as was needful, and mighty glad of it we were.
Leaving the pole in the earth, we set about boring in the floor of our hut, not beginning midway between the door-posts, as we should have done if we had encountered no obstacle, but a little to one side. We proceeded here in the same manner as we had done in the bank of the lake, using a sharp-pointed pole, only we drove it down in a vertical direction; but we soon found that this would not effect our purpose, as indeed we might have known before if we had thought about it, for it was necessary that we should make a clean hole, which could not be done by driving in a pole. After considering of it, we determined to get a large piece of bamboo stalk, at least five inches across, and to drive that into the earth with the pummet we had used in building the hut. This we did, and placing the bamboo (a piece about three feet long) in the hole we had already begun to drive, we dealt it several heavy blows with the pummet, by this means driving it into the ground, and at the same time forcing some earth up into its hollow interior. Then we took the bamboo out, and carrying it outside the hut, poked all the earth out of it, and when it was empty, put it once more into the hole, and smote it again as before. This was a very tedious business, for as the hole went deeper we had to use a longer piece of bamboo, and when we had near finished the bamboo broke in the middle, and we had to dig to a depth of three feet or more around the hole before we could reach the lower portion to pull it out again, at which Billy was very wroth, because the excavation had to be filled in again, so as to bring the floor to its former level. However, we continued until the hole was seven or eight feet deep, at which depth we thought we should come to the pole we had driven through the bank; but it would have been scarcely less than a miracle if we had bored the hole to the exact spot, and we had indeed to enlarge its circumference until it measured full thirty inches across, and not till then did we come to the pole. When we did strike this we were both very joyful, for we had been working at it for four full days, and had yet got but a very little way in our design.
