The tarag stood for a moment looking about him—first up at the vast audience and then about the arena. He did not seem to see me at all, but his eyes fell presently upon the girl. A hideous roar broke from his titanic lungs—a roar which ended in a long-drawn scream that is more human than the death-cry of a tortured woman—more human but more awesome. I could scarce restrain a shudder.

Slowly the beast turned and moved toward the girl. Then it was that I came to myself and to a realization of my duty. Quickly and as noiselessly as possible I ran down the arena in pursuit of the grim creature. As I ran I drew one of my pitifully futile weapons. Ah! Could I but have had my lost express-gun in my hands at that moment! A single well-placed shot would have crumbled even this great monster. The best I could hope to accomplish was to divert the thing from the girl to myself and then to place as many bullets as possible in it before it reached and mauled me into insensibility and death.

There is a certain unwritten law of the arena that vouchsafes freedom and immunity to the victor, be he beast or human being—both of whom, by the way, are all the same to the Mahar. That is, they were accustomed to look upon man as a lower animal before Perry and I broke through the Pellucidarian crust, but I imagine that they were beginning to alter their views a trifle and to realize that in the gilak—their word for human being—they had a highly organized, reasoning being to contend with.

Be that as it may, the chances were that the tarag alone would profit by the law of the arena. A few more of his long strides, a prodigious leap, and he would be upon the girl. I raised a revolver and fired. The bullet struck him in the left hind leg. It couldn’t have damaged him much; but the report of the shot brought him around, facing me.

I think the snarling visage of a huge, enraged, saber-toothed tiger is one of the most terrible sights in the world. Especially if he be snarling at you and there be nothing between the two of you but bare sand.

Even as he faced me a little cry from the girl carried my eyes beyond the brute to her face. Hers was fastened upon me with an expression of incredulity that baffles description. There was both hope and horror in them, too.

“Dian!” I cried. “My Heavens, Dian!”

I saw her lips form the name David, as with raised javelin she rushed forward upon the tarag. She was a tigress then—a primitive savage female defending her loved one. Before she could reach the beast with her puny weapon, I fired again at the point where the tarag’s neck met his left shoulder. If I could get a bullet through there it might reach his heart. The bullet didn’t reach his heart, but it stopped him for an instant.

It was then that a strange thing happened. I heard a great hissing from the stands occupied by the Mahars, and as I glanced toward them I saw three mighty thipdars—the winged dragons that guard the queen, or, as Perry calls them, pterodactyls—rise swiftly from their rocks and dart lightning-like, toward the center of the arena. They are huge, powerful reptiles. One of them, with the advantage which his wings might give him, would easily be a match for a cave bear or a tarag.

These three, to my consternation, swooped down upon the tarag as he was gathering himself for a final charge upon me. They buried their talons in his back and lifted him bodily from the arena as if he had been a chicken in the clutches of a hawk.
