“Yes,” he pursued with animation, “this is a fossil man, the contemporary of the mastodons whose remains fill this amphitheatre. But if you ask me how he came there, how those strata on which he lay slipped down into this enormous hollow in the globe, I confess I cannot answer that question. No doubt in the post-tertiary period considerable commotions were still disturbing the crust of the earth. The long-continued cooling of the globe produced chasms, fissures, clefts, and faults, into which, very probably, portions of the upper earth may have fallen. I make no rash assertions; but there is the man surrounded by his own works, by hatchets, by flint arrowheads, which are the characteristics of the stone age. And unless he came here, like myself, as a tourist on a visit and as a pioneer of science, I can entertain no doubt of the authenticity of his remote origin.”
