Another hard day’s work saw my house completed, and not only completed, but furnished; for in addition to a door--three feet high by two broad--which could be firmly secured by a lashing, it boasted a bedstead--a structure of sticks much resembling a wooden gridiron on eight small posts, on which I could spread my mats, and sleep clear of the damp ground. In this palatial residence I took up my abode in state as soon as it was dark, and by way of making it more cheerful, kindled a fire in the middle of the floor, by which I got not only light--and a great deal of smoke--but a warmth that was most grateful, for the nights were now damp and very chilly. Here, upon my new bed, I sat through the long evening, with the door shut and fastened, and the flickering flames lighting up the little interior, uncommonly elated at finding myself so comfortably housed, and full of enthusiasm for the work that the morrow was to see begun. For now that I had a comfortable home, the building of the canoe must be pushed forward with all speed, so that I could make my dash for the coast as soon as the river was full. Long that night I sat cogitating upon my scheme, and as it took more definite shape and details suggested themselves, I covered my dirty white _riga_ with figures and diagrams scrawled on it with a stump of charcoal from the fire. The problem to be worked out was simple enough. The weight of the gold I estimated at half a ton; it could hardly be more, for Bukári and I had carried it from the mine to the river in five journeys, each carrying, of course, a tenth part of the whole treasure. My own weight was eleven stone--probably less now--or a hundred and fifty-four pounds, making, with the gold, a total of twelve hundred and seventy-four pounds. This weight added to the weight of the canoe itself, represented the displacement of the vessel when fully loaded, that is to say, the loaded canoe would displace, in floating, this weight of water. Now a cubic foot of water weighs sixty-two and a half pounds, or a little less in the Tropics. Calling it sixty-two, to be on the safe side, the gold would displace eighteen cubic feet of water, and my body would displace two and a half, a total of twenty and a half cubic feet without reckoning the weight of the canoe.
