I can still hear, in memory, those coolly spoken words; and I can still remember my remonstrances. I seemed desperately anxious to accompany my friend into those sepulchral depths, yet he proved inflexibly obdurate. At one time he threatened to abandon the expedition if I remained insistent; a threat which proved effective, since he alone held the key to the thing. All this I can still remember, though I no longer know what manner of thing we sought. After he had obtained my reluctant acquiescence in his design, Warren picked up the reel of wire and adjusted the instruments. At his nod I took one of the latter and seated myself upon an aged, discolored gravestone close by the newly uncovered aperture. Then he shook my hand, shouldered the coil of wire, and disappeared within that indescribable ossuary.
