During our mutual inquiries and explanations, the Frenchman had kept the canoe close alongside of us; he now braced round the yard of his triangular sail, which had been shaking in the wind, and began to draw ahead. The young native who had interfered so effectually in Max's behalf, observing the eagerness with which we had devoured the doughy mass of pounded bread-fruit, tossed another cake of the same substance into the boat as we separated, which, when distributed, afforded a morsel or two to each of us. I had particularly observed this boy on the first approach of the canoe, from the circumstance of his occupying a small raised platform, or dais, of wicker-work, covered with mats. As our sail had been entirely disengaged from the mast and gaff, it was quite a piece of work to rig it again for service, and by the time this was effected, the canoe was some distance ahead of us: though she was far better adapted than the yawl for sailing with a light breeze, yet we nearly held our own with her, after once getting fairly under way. When the wind first sprang up, the sky had become slightly overcast with broken masses of clouds, of a peculiar and unusual appearance. From the most considerable of these masses, radiated, as from a centre, long lines, like pencils of light, running in straight, regularly diverging rays, to the ocean. We had been sailing in the wake of the canoe, perhaps half an hour, when I observed in the south-west a singularly shaped cloud, to which a dark column, extending downward to the sea, appeared to be attached. This column was quite narrow at the base, but enlarged as it rose, until just below the point of union with the cloud, it spread outward like a gothic pillar, diverging into arches as it meets the roof. I surveyed this strange spectacle for several minutes before its true character occurred to me. It was already observed by those in the canoe, and from their exclamations and gestures, they evidently viewed it with apprehension and dread. It was moving slowly towards us, and we also watched, with feelings in which alarm began to predominate over curiosity and interest, the majestic approach of this vast body of water, (as we now perceived it to be), held by some secret power suspended between heaven and earth. "It appears to be moving north before the wind," said Arthur, at length; "if it keeps on its present course, it will pass by, at a safe distance on our left."
