r, and dispersed every appearance of this kind, although the black clouds remained until about ten, when the wind veered round to the W.S.W., and settled there in a moderate steady gale, and the weather cleared up."--W. "The nature of water-spouts and their causes, being hitherto very little known, we were extremely attentive to mark every little circumstance attendant on this appearance. Their base, where the water of the sea was violently agitated, and rose in a spiral form in vapours, was a broad spot, which looked bright and yellowish when illuminated by the sun. The column was of a cylindrical form, rather increasing in width towards the upper extremity. These columns moved forward on the surface of the sea, and the clouds not following them with equal rapidity, they assumed a bent or incurvated shape, and frequently appeared crossing each other, evidently proceeding in different directions; from whence we concluded, that it being calm, each of these water-spouts caused a wind of its own. At last they broke one after another, being probably too much distended by the difference between their motion and that of the clouds. In proportion as the clouds came nearer to us, the sea appeared more and more covered with short broken waves, and the wind continually veered all round the compass without fixing in any point. We soon saw a spot on the sea, within two hundred fathoms of us, in a violent agitation. The water, in a space of fifty or sixty fathoms, moved towards the centre, and there rising into vapour, by the force of the whirling motion, ascended in a spiral form towards the clouds. Some hailstones fell on board about this time, and the clouds looked exceedingly black and louring above us. Directly over the whirl-pool, if I may so call the agitated spot on the sea, a cloud gradually tapered into a long slender tube, which seemed to descend to meet the rising spiral, and soon united with it into a short column of a cylindrical form. We could distinctly observe the water hurled upwards with the greatest violence in a spiral, and it appeared that it left a hollow space in the centre; so that we concluded the water only formed a hollow tube, instead of a solid column. We were strongly confirmed in this belief by the colour, which was exactly like any hollow glass-tube. After some t
