I looked, shaking my head incredulously. But though at first I was unbelieving I had to yield to the evidence of my senses.

In fact, at a distance of a quarter of a mile, leaning against the trunk of a gigantic kauri, stood a human being, the Proteus of those subterranean regions, a new son of Neptune, watching this countless herd of mastodons.

Immanis pecoris custos, immanior ipse. [1]

[1] "The shepherd of gigantic herds, and huger still himself."

Yes, truly, huger still himself. It was no longer a fossil being like him whose dried remains we had easily lifted up in the field of bones; it was a giant, able to control those monsters. In stature he was at least twelve feet high. His head, huge and unshapely as a buffalo's, was half hidden in the thick and tangled growth of his unkempt hair. It most resembled the mane of the primitive elephant. In his hand he wielded with ease an enormous bough, a staff worthy of this shepherd of the geologic period.

We stood petrified and speechless with amazement. But he might see us! We must fly!

"Come, do come!" I said to my uncle, who for once allowed himself to be persuaded.

In another quarter of an hour our nimble heels had carried us beyond the reach of this horrible monster.

And yet, now that I can reflect quietly, now that my spirit has grown calm again, now that months have slipped by since this strange and supernatural meeting, what am I to think? what am I to believe? I must conclude that it was impossible that our senses had been deceived, that our eyes did not see what we supposed they saw. No human being lives in this subterranean world; no generation of men dwells in those inferior caverns of the globe, unknown to and unconnected with the inhabitants of its surface. It is absurd to believe it!

I had rather admit that it may have been some animal whose structure resembled the human, some ape or baboon of the early geological ages, some protopitheca, or some mesopitheca, some early or middle ape like that discovered by Mr. Lartet in the bone cave of Sansau. But this creature surpassed in stature all the measurements known in modern palæontology. But that a man, a living man, and therefore whole generations doubtless besides, should be buried there in the bowels of the earth, is impossible.
