Beyond this there is an inhabited mountainous island, which is said to contain mines of silver; but as it does not lie in the usual track of shipping, many have searched for it in vain, though remarkable for a very lofty mountain called Kashenai. A ship, sailing in its latitude, once got sight of this mountain, and steered for the coast, where some people were sent on shore to cut wood: The men kindled a fire, from which there ran out some melted silver, on which they concluded that there must have been a silver mine in the place, and they shipped a considerable quantity of the earth or ore; but they encountered a terrible storm on their voyage back, and were forced to throw all their ore overboard to lighten the vessel. Since that time the mountain has been several times carefully sought for, but no one has ever been able to find it again. There are many such islands in those seas, more in number than can be reckoned; some inaccessible by seamen, and some unknown to them. It often happens in these seas that a whitish cloud suddenly appears over-head, which lets down a long thin tongue or spout, quite to the surface of the water, which is then turned swiftly round as if by a whirlwind, and if a vessel happens to be in the way, she is immediately swallowed up in the vortex. At length this cloud mounts up again and discharges itself in prodigious rain; but it is not known whether this water is sucked up by the cloud, or how this phenomenon comes to pass. All these seas are subject to prodigious storms, which make them boil up like water over a fire; at which times the waves dash the ships against the islands with unspeakable violence, to their utter destruction; and even fish; of all sizes are thrown dead on shore, against the rocks, by the extreme agitation of the sea. The wind which commonly blows upon the sea of Herkend is from a different quarter, or from the N.W.; but this sea is likewise subject to as violent agitations as those just mentioned, and there ambergris is torn up from the bottom, particularly where it is very deep; and the deeper the sea so much the more valuable is the ambergris which it produces. It is likewise observed, that when this sea is tossed by tempestuous winds it sparkles like fire; and it is infested with a certain kind of fish called Lockham, which frequently preys upon men[5]. * * * * *
