The right-hand portion of Martel Avenue brings us soon to the bed of a brook that must at times be deeply covered by flowing water. Ripple marks of sand alternate with flat masses of jet-black polished flint. Knots of wood, roots of corn-stalks, and other objects indicate that they were recently swept down hither from the surface. Two adjacent domes are named for the intrepid guide, John M. Nelson, but beyond them some hardy pioneer had inscribed on a rock the date 1848. Mr. Norman A. Parrish came as far as this in 1904, but the distinction of availing himself of footholds over a risky limestone slip and crossing where others had turned back belongs to Mr. B. F. Einbigler, already mentioned as having descended the Maelström. For him the great overhanging dome is named, while a still grander one about a hundred yards beyond was named by him “Edna Dome” for his sister, who subsequently visited it. Instead of narrowing to an apex, as most domes do, Edna Dome broadens at the top, seeming to open into a cross-cavern. This conjecture remains to be verified by some climber. Edward Hawkins scaled the wall of the pit underneath Einbigler’s Dome, May 15, 1907, being followed by Einbigler, Bransford, and at another visit by Mr. H. M. Pinson, who took along the head-light of an automobile for illumination. This searchlight was still there on the occasion of my own visit, on the 18th of June, 1907, a month afterward, in company with William Bransford and Frank Barry, guides. Passing through Hawkins’ Way and scaling a wall at its end, we were on the level floor of a dome sixty feet in diameter and from one hundred and fifty to two hundred feet high. A tall arched gateway opened from this into a second dome of equal size; and through similar gateways we entered in succession five vast domes arranged as a sigmoidal group. From the fifth a window opens into an irregular room, where a downfall of rocks blocks further progress. In this fifth dome also a waterfall leaps from the apex to the floor, where it vanishes into a chasm. The majestic walls rise in horizontal tiers, each tier about ten feet in thickness and fringed by beautiful stalactites. The mighty masonry ascends in narrowing circles till the powerful searchlight barely enables us to discern the oval white tablet forming the apex, girt by onyx pendants. Vertically the walls are richly corrugated from top to bottom. The entire series of five united domes is four times the magnitude of Gorin’s Dome. Ages on ages were needed for the chemical and mechanical action whereby this surprising cathedral was carved in silence broken only by the wild, pattering waterfall or the heavier cataract. Let me anew express my obligation to the Mammoth Cave management for having marked their appreciation of my long-continued and enthusiastic interest in their wonderful cavern by naming, with the approval of the discoverer and the guides, this remarkable group of domes “Hovey’s Cathedral.”
