Immediately afterwards he ran into another mist or vapour, thicker, if anything, and which quite obscured his view. It seemed like a great cloud on the surface of the water, and broader than those he had previously entered. Suddenly the canoe stopped with a tremendous jerk, which pitched him forward on his knees, the mast cracked, and there was a noise of splitting wood. As soon as he could get up, Felix saw, to his bitter sorrow, that the canoe had split longitudinally; the water came up through the split, and the boat was held together only by the beams of the outrigger. He had run aground on a large sharp flint embedded in a chalk floor, which had split the poplar wood of the canoe like an axe. The voyage was over, for the least strain would cause the canoe to part in two, and if she were washed off the ground she would be water-logged. In half a minute the mist passed, leaving him in the bright day, shipwrecked. Felix now saw that the waters were white with suspended chalk, and sounding with the paddle, found that the depth was but a few inches. He had driven at full speed on a reef. There was no danger, for the distance to the shore was hardly two hundred yards, and judging by the appearance of the water, it was shallow all the way. But his canoe, the product of so much labour, and in which he had voyaged so far, his canoe was destroyed. He could not repair her; he doubted whether it could have been done successfully even at home with Oliver to help him. He could sail no farther; there was nothing for it but to get ashore and travel on foot. If the wind rose higher, the waves would soon break clean over her, and she would go to pieces. With a heavy heart, Felix took his paddle and stepped overboard. Feeling with the paddle, he plumbed the depth in front of him, and, as he expected, walked all the way to the shore, no deeper than his knees. This was fortunate, as it enabled him to convey his things to land without loss. He wrapped up the tools and manuscripts in one of his hunter's hides. When the whole cargo was landed, he sat down sorrowfully at the foot of the cliff, and looked out at the broken mast and sail, still flapping uselessly in the breeze. It was a long time before he recovered himself, and set to work mechanically to bury the crossbow, hunter's hides, tools, and manuscripts, under a heap of pebbles. As the cliff, though low, was perpendicular, he could not scale it, else he would have preferred to conceal them in the woods above. To pile pebbles over them was the best he could do for the present; he intended to return for them when he discovered a path up the cliff. He then started, taking only his bow and arrows.
