passage may be about twelve or fourteen feet, and its breadth about six or eight, neatly formed into a Gothic portal by the hand of nature. The lower part of this porch is closed by a ledge of rock, rising to the height of between five and six feet, and which I can compare to nothing but the hatch-door of a shop. Beneath this hatch a brook finds its way out, forms a black deep pool before the Gothic archway, and then escapes to the sea, and forms the creek in which we landed. It is somewhat difficult to approach this strange pass, so as to gain a view into the interior of the cavern. By clambering along a broken and dangerous cliff, you can, however, look into it; but only so far as to see a twilight space filled with dark-colored water in great agitation, and representing a subterranean lake, moved by some fearful convulsion of nature. How this pond is supplied with water you cannot see from even this point of vantage, but you are made partly sensible of the truth by a sound like the dashing of a sullen cataract within the bowels of the earth. Here the adventure has usually been abandoned, and Mr. Anderson only mentioned two travellers whose curiosity had led them farther. We were resolved, however, to see the adventures of this new cave of Montesinos to an end. Duff had already secured the use of a fisher's boat and its hands, our own long-boat being too heavy and far too valuable to be ventured upon this Cocytus. Accordingly the skiff was dragged up the brook to the rocky ledge or hatch which barred up the interior cavern, and there, by force of hands, our boat's crew and two or three fishers first raised the boat's bow upon the ledge of rock, then brought her to a level, being poised upon that narrow hatch, and lastly launched her down into the dark and deep subterranean lake within. The entrance was so narrow, and the boat so clumsy, that we, who were all this while clinging to the rock like sea-fowl, and with scarce more secure footing, were greatly alarmed for the safety of our trusty sailors. At the instant when the boat sloped inward to the cave, a Highlander threw himself into it with great boldness and dexterity, and, at the expense of some bruises, shared its precipitate fall into the waters under the earth. This dangerous exploit was to prevent the boat drifting away from us, but a cord at its stern would have been a safer and surer expedient.
