where are we?" I exclaimed. "This thing is beginning to get on my nerves."

"I think that I may state quite positively, David," he commenced, "that we are—" but he got no further. From behind us in the vicinity of the prospector there came the most thunderous, awe-inspiring roar that ever had fallen upon my ears. With one accord we turned to discover the author of that fearsome noise.

Had I still retained the suspicion that we were on earth the sight that met my eyes would quite entirely have banished it. Emerging from the forest was a colossal beast which closely resembled a bear. It was fully as large as the largest elephant and with great forepaws armed with huge claws. Its nose, or snout, depended nearly a foot below its lower jaw, much after the manner of a rudimentary trunk. The giant body was covered by a coat of thick, shaggy hair.

Roaring horribly it came toward us at a ponderous, shuffling trot. I turned to Perry to suggest that it might be wise to seek other surroundings—the idea had evidently occurred to Perry previously, for he was already a hundred paces away, and with each second his prodigious bounds increased the distance. I had never guessed what latent speed possibilities the old gentleman possessed.

I saw that he was headed toward a little point of the forest which ran out toward the sea not far from where we had been standing, and as the mighty creature, the sight of which had galvanized him into such remarkable action, was forging steadily toward me, I set off after Perry, though at a somewhat more decorous pace. It was evident that the massive beast pursuing us was not built for speed, so all that I considered necessary was to gain the trees sufficiently ahead of it to enable me to climb to the safety of some great branch before it came up.

Notwithstanding our danger I could not help but laugh at Perry's frantic capers as he essayed to gain the safety of the lower branches of the trees he now had reached. The stems were bare for a distance of some fifteen feet—at least on those trees which Perry attempted to ascend, for the suggestion of safety carried by the larger of the forest giants had evidently attracted him to them. A dozen times he scrambled up the trunks like a huge cat only to fall back to the ground once more, and with each failure he cast a horrified glance over his shoulder at the oncoming brute, simultaneously emitting terror-stricken shrieks that awoke the echoes of the grim forest.

At length he spied a dangling creeper about the bigness of one's wrist, and when I reached the trees he was racing madly up it, hand over hand. He had almost reached the lowest branch of the tree from which the creeper depended when the thing parted beneath his weight and he fell sprawling at my feet.

The misfortune now was no longer amusing, for the beast was already too close to us for comfort. Seizing Perry by the shoulder I dragged him to his feet, and rushing to a smaller tree—one that he could easily encircle with his arms and legs—I boosted him as far up as I could, and then left him to his fate, for a glance over my shoulder revealed the awful beast almost upon me.

It was the great size of the thing alone that saved me. Its enormous bulk rendered it too slow upon its feet to cope with the agility of my young muscles, and so I was enabled to dodge out of its way and run completely behind it before its slow wits could direct it in pursuit.

The few seconds of grace that this gave me found me safely lodged in the branches of a tree a few paces from that in which Perry had at last found a haven.

Did I say safely lodged? At the time I thought we were quite safe, and so did Perry. He was praying—raising his voice in thanksgiving at our deliverance—and had just completed a sort of paeon of gratitude that the thing couldn't climb a tree when without warning it reared up beneath him on its enormous tail and hind feet, and reached those fearfully armed paws quite to the branch upon which he crouched.

The accompanying roar was all but drowned in Perry's scream of fright, and he came near tumbling headlong into the gaping jaws beneath him, so precipitate was his impetuous haste to vacate the dangerous limb. It was with a deep sigh of relief that I saw him gain a higher branch in safety.

And then the brute did that which froze us both anew with horror. Grasping the tree's stem with his powerful paws he dragged down with all the great weight of his huge bulk and all the irresistible force of those mighty muscles. Slowly, but surely, the stem began to bend toward him. Inch by inch he worked his paws upward as the tree leaned more and more from the perpendicular. Perry clung chattering in a panic of terror. Higher and higher into the bending and swaying tree he clambered. More and more rapidly was the tree top inclining toward the ground.

I saw now why the great brute was armed with such enormous paws. The use that he was putting them to was precisely that for which nature had intended them. The sloth-like creature was herbivorous, and to feed that mighty carcass entire trees must be stripped of their foliage. The reason for its attacking us might easily be accounted for on the supposition of an ugly disposition such as that which the fierce and stupid rhinoceros of Africa possesses. But these were later reflections. At the moment I was too frantic with apprehension on Perry's behalf to consider aught other than a means to save him from the death that loomed so close.

Realizing that I could outdistance the clumsy brute in the open, I dropped from my leafy sanctuary intent only on distracting the thing's attention from Perry long enough to enable the old man to gain the safety of a larger tree. There were many close by which not even the terrific strength of that titanic monster could bend.

As I touched the ground I snatched a broken limb from the tangled mass that matted the jungle-like floor of the forest and, leaping unnoticed behind the shaggy back, dealt the brute a terrific blow. My plan worked like magic. From the previous slowness of the beast I had been led to look for no such marvelous agility as he now displayed. Releasing his hold upon the tree he dropped on all fours and at the same time swung his great, wicked tail with a force that would have broken every bone in my body had it struck me; but, fortunately, I had turned to flee at the very instant that I felt my blow land upon the towering back.

As it started in pursuit of me I made the mistake of running along the edge of the forest rather than making for the open beach. In a moment I was knee-deep in rotting vegetation, and the awful thing behind me was gaining rapidly as I floundered and fell in my efforts to extricate myself.

A fallen log gave me an instant's advantage, for climbing upon it I leaped to another a few paces farther on, and in this way was able to keep clear of the mush that carpeted the surrounding ground. But the zigzag course that this necessitated was placing such a heavy handicap upon me that my pursuer was steadily gaining upon me.

Suddenly from behind I heard a tumult of howls, and sharp, piercing barks—much the sound that a pack of wolves raises when in full cry. Involuntarily I glanced backward to discover the origin of this new and menacing note with the result that I missed my footing and went sprawling once more upon my face in the deep muck.

My mammoth enemy was so close by this time that I knew I must feel the weight of one of his terrible paws before I could rise, but to my surprise the blow did not fall upon me. The howling and snapping and barking of the new element which had been infused into the melee now seemed centered quite close behind me, and as I raised myself upon my hands and glanced around I saw what it was that had distracted the DYRYTH, as I afterward learned the thing is called, from my trail.

It was surrounded by a pack of some hundred wolf-like creatures—wild dogs they seemed—that rushed growling and snapping in upon it from all sides, so that they sank their
