the spray which was thrown off from the circle formed by the lower part of the column, rose several feet above the level of the sea. It passed about a mile astern of the ship.
Occasionally, when passing nearer to a ship than was deemed safe, a waterspout has been dissipated by a cannon-shot, as represented in our engraving.
Such are the usual appearances and actions of waterspouts. They are not, however, properly named, being simply whirlwinds at sea, instead of whirlwinds on land. Professor Oersted suggests the name "storm-pillar," as being a more appropriate term.
It does not follow that a large ship would inevitably be destroyed if brought within the vortex of a waterspout; but it is certain that she would run the risk of being dismasted, and perhaps thrown on her beam-ends. Navigators have not had suffiient experience of the power of waterspouts to pronounce authoritatively on that point,—and it is to be hoped they never will.
Captain Beechy, in his narrative of a voyage to the Pacific, describes one into which his ship actually entered, and from which he received extremely rough handling before he was set free. But this might not have been a very large waterspout; and it is not absolutely certain whether he was quite within its vortex, or was merely brushed by the skirts of its outer garment.
