The Captain had broken his own rules. Watching his opportunity, under cover of the night, he had taken a canoe, and had secretly crossed the channel to the Holy Island. No one had been near him at the time but the chief's son. The lad had vainly tried to induce him to abandon his desperate enterprise, and had vainly waited on the shore in the hope of hearing the sound of the paddle announcing his return. Beyond all reasonable doubt, the infatuated man had set foot on the shores of the tabooed island. The one chance for his life was to conceal what he had done, until the ship could be got out of the harbor, and then (if no harm had come to him in the interval) to rescue him after nightfall. It was decided to spread the report that he had really been taken ill, and that he was confined to his cabin. The chief's son, whose heart the Captain's kindness had won, could be trusted to do this, and to keep the secret faithfully for his good friend's sake. Toward noon, the next day, they attempted to take the ship to sea, and failed for want of wind. Hour by hour, the heat grew more oppressive. As the day declined, there were ominous appearances in the western heaven. The natives, who had given some trouble during the day by their anxiety to see the Captain, and by their curiosity to know the cause of the sudden preparations for the ship's departure, all went ashore together, looking suspiciously at the sky, and reappeared no more. Just at midnight, the ship (still in her snug berth inside the reef) suddenly trembled from her keel to her uppermost masts. Mr. Duncalf, surrounded by the startled crew, shook his knotty fist at the island as if he could see it in the dark. "My lads, what did I tell you? That was a shock of earthquake." With the morning the threatening aspect of the weather unexpectedly disappeared. A faint hot breeze from the land, just enough to give the ship steerage-way, offered Mr. Duncalf a chance of getting to sea. Slowly the _Fortuna_, with the mate himself at the wheel, half sailed, half drifted into the open ocean. At a distance of barely two miles from the island the breeze was felt no more, and the vessel lay becalmed for the rest of the day. At night the men waited their orders, expecting to be sent after their Captain in one of the boats. The intense darkness, the airless heat, and a second shock of earthquake (faintly felt in the ship at her present distance from the land) warned the mate to be cautious. "I smell mischief in the air," said Mr. Duncalf. "The Captain must wait till I am surer of the weather."
