As I proceeded I began to speculate upon the possible actions of Raja when we should enter the presence of other men than myself. The brute was padding softly at my side, his sensitive nose constantly atwitch and his fierce eyes moving restlessly from side to side—nothing would ever take Raja unawares!

The more I thought upon the matter the greater became my perturbation. I did not want Raja to attack any of the people upon whose friendship I so greatly depended, nor did I want him injured or slain by them.

I wondered if Raja would stand for a leash. His head as he paced beside me was level with my hip. I laid my hand upon it caressingly. As I did so he turned and looked up into my face, his jaws parting and his red tongue lolling as you have seen your own dog’s beneath a love pat.

“Just been waiting all your life to be tamed and loved, haven’t you, old man?” I asked. “You’re nothing but a good pup, and the man who put the hyaeno in your name ought to be sued for libel.”

Raja bared his mighty fangs with upcurled, snarling lips and licked my hand.

“You’re grinning, you old fraud, you!” I cried. “If you’re not, I’ll eat you. I’ll bet a doughnut you’re nothing but some kid’s poor old Fido, masquerading around as a real, live man-eater.”

Raja whined. And so we walked on together toward Thuria—I talking to the beast at my side, and he seeming to enjoy my company no less than I enjoyed his. If you don’t think it’s lonesome wandering all by yourself through savage, unknown Pellucidar, why, just try it, and you will not wonder that I was glad of the company of this first dog—this living replica of the fierce and now extinct hyaenodon of the outer crust that hunted in savage packs the great elk across the snows of southern France, in the days when the mastodon roamed at will over the broad continent of which the British Isles were then a part, and perchance left his footprints and his bones in the sands of Atlantis as well.

Thus I dreamed as we moved on toward Thuria. My dreaming was rudely shattered by a savage growl from Raja. I looked down at him. He had stopped in his tracks as one turned to stone. A thin ridge of stiff hair bristled along the entire length of his spine. His yellow green eyes were fastened upon the scrubby jungle at our right.

I fastened my fingers in the bristles at his neck and turned my eyes in the direction that his pointed. At first I saw nothing. Then a slight movement of the bushes riveted my attention. I thought it must be some wild beast, and was glad of the primitive weapons I had taken from the bodies of the warriors who had attacked me.

Presently I distinguished two eyes peering at us from the vegetation. I took a step in their direction, and as I did so a youth arose and fled precipitately in the direction we had been going. Raja struggled to be after him, but I held tightly to his neck, an act which he did not seem to relish, for he turned on me with bared fangs.
