Felix, remembering the character of the mariners, resolved to keep well away from them, but to watch their course as a guide to himself. The mainland now ran abruptly to the north, and the canoe, as he brought her more into the wind, sprang forward at a rapid pace. The outrigger prevented her from making any leeway, or heeling over, and the large spread of sail forced her swiftly through the water. He had lost sight of the ship behind some islands, and as he approached these, began to ask himself if he had not better haul down his sail there, as he must now be getting near her, when to his surprise, on coming close, he saw her great square sail in the middle, as it seemed, of the land. The shore there was flat, the hills which had hitherto bounded it suddenly ceasing; it was overgrown with reeds and flags, and about two miles away the dark sail of the merchantman drifted over these, the hull being hidden. He at once knew that he had reached the western mouth of the straits which divide the southern and northern mainland. When he went to see the channel on foot through the forest, he must have struck it a mile or two more to the east, where it wound under the hills. In another half hour he arrived at the opening of the strait; it was about a mile wide, and either shore was quite flat, that on the right for a short distance, the range of downs approaching within two miles; that on the left, or north, was level as far as he could see. He had now again to lower his sail, to get the outrigger on his lee as he turned to the right and steered due east into the channel. So long as the shore was level, he had no difficulty, for the wind drew over it, but when the hills gradually came near and almost overhung the channel, they shut off much of the breeze, and his progress was slow. When it turned and ran narrowing every moment to the south, the wind failed him altogether. On the right shore, wooded hills rose from the water like a wall; on the left, it was a perfect plain. He could see nothing of the merchantman, although he knew that she could not sail here, but must be working through with her sweeps. Her heavy hull and bluff bow must make the rowing a slow and laborious process; therefore she could not be far ahead, but was concealed by the winding of the strait. He lowered the sail, as it was now useless, and began to paddle; in a very short time he found the heat under the hills oppressive when thus working. He had now been afloat between six and seven hours, and must have come fully thirty miles, perhaps rather more than twenty in a straight line, and he felt somewhat weary and cramped from sitting so long in the canoe.
