This discovery threw light on the other. The piece of black ore, weighing about seven pounds, was in reality silver coin, that a century of submersion had reduced to the very appearance it wore before it ever went into the furnace. He dug with fresh energy on this discovery, but found nothing more in the ship that day. Then it occurred to him to carry off a few hundred-weight of pink coral. He got some fine specimens; and, while he was at that work, he fell in with a piece that looked very solid at the root and unnaturally heavy. On a nearer examination this proved to be a foreign substance incrusted with coral. It had twined and twisted and curled over the thing in a most unheard-of way. Robert took it home, and, by rubbing here and there with lemon juice, at last satisfied himself that this object was a silver box about the size of an octavo volume. It had no keyhole, had evidently been soldered up for greater security, and Robert was left to conjecture how it had come there. He connected it at once with the ship, and felt assured that some attempt had been made to save it. There it had lain by the side of the vessel all these years, but, falling clear of the sand, had been embraced by the growing coral, and was now a curiosity, if not a treasure. He would not break the coral, but put it on board his life-boat just as it was. And now he dug no more. He thought he could sell the galleon as well as the island, by sample, and he was impatient to be gone. He reproached himself, a little unjustly, for allowing a woman to undertake the task of clearing him. "To what annoyances, and perhaps affronts, have I exposed her!" said he. "No, it is a man's business to defend, not to be defended." To conclude: At high tide one fine afternoon he went on board with Ponto, and, hoisting his foresail only, crossed the bay, ranging along the island till he reached the bluff. He got under this, and, by means of his compass and previous observations, set the boat's head exactly on the line the ducks used to take. Then he set his mainsail too, and stretched boldly out across the great Pacific Ocean. Time seems to wear out everything, even bad luck. It ran strong against Robert Penfold for years. But, when it had struck its worst blow, and parted him and Helen Rolleston, it relaxed, and a tide of good luck set in, which, unfortunately, the broken-hearted man could not appreciate at the time. However, so it was. He wanted oil; and a whale came ashore. He wanted treasure, and the sea gave him a little back of all it had swallowed; and now he wanted fine weather; and the ocean for days and nights was like peach-colored glass, dimpled here and there; and soft westerly airs fanned him along by night and day.
