The second mate and Roger remained on board with the starboard watch, the drawing giving the advantage to the others; and these, with the captain and first mate, were soon rowing towards the shore. Those on board, although disappointed that fate had decided against them, had their share of amusement, for a good many canoes afterwards came off to them, filled with goods for barter; and as the captain, before leaving, had told the second mate that he could buy and sell with those who came out, a brisk trade was soon established. They had no fear of treachery from the natives, who were in such dread of the white men that they would not venture to lift a hand against them, however great the odds might be; and they were, therefore, allowed to come on board and mix freely with the sailors. The contents of the canoes, chiefly fruit and vegetables, were spread out on the deck, and the mate and Roger bargained with them, giving them little looking glasses, and strings of beads, in exchange for their wares. "They are mighty reasonable in their demands," Roger said to Pengarvan. "It seems almost a shame to take these great baskets of fruit and vegetables, in return for such trifles." "They are not trifles to them," the mate replied, "and there is nothing unfair in the exchange. These things are to them what gold and jewels are to us. We would give, gladly, a score of boatloads of vegetables for a diamond the size of a pea; and these glass beads are as valuable, in their eyes, as diamonds are in ours." After buying up the main stock, they trafficked with the natives for the little ornaments they wore, necklaces and bracelets cunningly worked with bright shells and seeds, and weapons of curiously carved wood. At nightfall the other boats returned, laden down with fruit and vegetables. "'We must buy no more of these commodities, at present," Captain Reuben said, when he saw what had been purchased on board. "We have got enough to last us as long as they will keep, eat we never so heartily;" and indeed, the next day a number of the crew were ill, from the quantity of fruit that they consumed. This, however, soon passed off, and the change of diet did great good. The scurvy disappeared, and in a short time all--even those who had suffered most--were again fit for duty.
