indeed we partly saw by the light he carried) that the enchantment of MacAllister's cave terminates with this portal, a little beyond which there was only a rude cavern, speedily choked with stones and earth. But the pool on the brink of which we stood, surrounded by the most fanciful mouldings, in a substance resembling white marble, and distinguished by the depth and purity of its waters, might have been the bathing grotto of a naiad. The groups of combined figures projecting or embossed, by which the pool is surrounded, are exquisitely elegant and fanciful. A statuary might catch beautiful hints from the singular and romantic disposition of those stalactites. There is scarce a form or group on which active fancy may not trace figures or grotesque ornaments, which have been gradually moulded in this cavern by the dropping of the calcareous water hardening into petrifactions. Many of these fine groups have been injured by the senseless rage for appropriation of recent tourists; and the grotto has lost, (I am informed,) through the smoke of torches, something of that vivid silver tint which was originally one of its chief distinctions. But enough of beauty remains to compensate for all that may be lost."[92] But these tales are the _nugæ canoræ_ of the naturalist. Once more,--Is there any substratum of truth underlying these fancies? or must they be unhesitatingly dismissed to the region of fable? Certainly, if there were not two or three narratives which have an air of veracity and dependableness, bearing out the belief to some slight extent, I should not have noticed it here. How simple and circumstantial is this story told by old Hudson, the renowned navigator! a man whose narrative is more than usually dry and destitute of everything like, not only imagination, but even an imaginative aspect of ordinary circumstances. On the 15th of June, when in lat. 75°, trying to force a passage to the pole near Nova Zembla, he records the following incident: "This morning one of our company looking overboard saw a mermaid; and calling up some of the company to see her, one more came up, and by that time she was come close to the ship's side, looking earnestly on the men. A little after, a sea came and overturned her. From the navel upward, her back and breasts were like a woman's, as they say that saw her; her body as big as one of us; her skin very white; and long hair hanging down behind, of colour black. In her going down they saw her tail, which was like the tail of a porpoise, and speckled like a mackerel. Their names that saw her were Thomas Hilles and Robert Rayner."[93]
