Being thus a prey to wretchedness I sat with my head in my hands, not heeding the heat of the sun, which was now beating fiercely down upon us, until I felt very sick and dizzy, and then I got up and looked for Billy, who had disappeared. But he had only gone into the wood to find food, it being nigh dinner-time. He came back and told me that there was nothing but bread-fruit, and that we could not eat, so we had to make our way to the cocoa-nut wood, which we did by descending to the beach and climbing up the slope as before. In going along the beach Billy picked up two or three shell-fish which he called clams, the purple kind, not the larger sort, which were very heavy; indeed, one of them would have made a meal for a family. We saw, too, several crabs of a very large size, some above two feet long; and Billy, idly poking his cudgel into a hole beside a rock, he could not draw it back, and when he peeped in to see what held it, he cried out that it had been seized by a great crab, and though he pulled very hard, he could not draw it out. When we came to our wood we ate cocoanuts and quenched our thirst with the juice, Billy striking them open with the sharp flint he had in his pocket; but I could not forbear wondering how we were to live without fresh water, of which we had seen none but what was in the lake, and that was a medicine we were by no means inclined to. Having appeased our hunger and thirst we were too listless to walk any more, and too miserable to talk to each other, and so we laid ourselves down and fell asleep. [Sidenote: Weapons] When I awoke I saw that Billy had been fashioning for himself a new club in place of that which had been seized by the robber crab, only this time he had made a better one. Having observed that the sharp flint, of which I have before spoken, had two notches on its blunt side, he had conceived the notion of binding it to his club, and so using it as an axe-head. At first he was much exercised, as he told me, how to fasten the two together, and sighed for some iron-wire, or at least some stout cord; but glancing around he spied a creeping plant with very long and slender tendrils, which he proved to be very tough, and breaking off some lengths of this with his flint, he had nearly finished binding the flint to his club.
