Then a loud, hoarse roar was heard, echoing through the forest. The startled travellers looked about on every side, but could see nothing to explain the sound; then it came again and again, while the colossal folds in front of them, half hidden by the trees, continued to rise and fall, lashing against the trees and shrubs with blows that seemed almost to shake the ground.

Matava advanced and fired other shots into the struggling monster; then, watching his opportunity, made a rush and dexterously cut off the creature’s head with a blow of his axe.

And now, looking towards the rock, they saw the ‘window’ entrance to the cavern, and the head of the big puma from which had proceeded the loud roars they had heard; and by the side of the puma was a pallid, thin, haggard face that they had some difficulty in recognising as Jack Templemore’s!

“You have come only just in time,” he said, in a weak voice, with a poor attempt at a smile, when the doctor had come near. “We were almost done for; at least, I know I am. I scarcely know whether I have strength enough to get the ladder out for you.”

They tied two lassoes together and threw one end in; this he fastened to the ladder, and, thus assisted, it was got out. Immediately the puma sprang down it and disappeared into the forest. Then the doctor, followed by Kingsford and Harry, climbed up and entered the cavern, to find Templemore lying on the floor unconscious.

He was suffering from a sprained ankle and a badly bruised arm, and was exhausted from want of food. It was some time before he could explain matters to his rescuers; and they, meantime, were anxiously wondering at finding him thus alone, with no sign about of his two friends. When he had briefly accounted for their absence, he told how he had been kept prisoner for more than a week by the great serpent that, all that time, had relentlessly watched and waited outside. But, apart from this, he could scarcely have got through the wood in his crippled state.

“Still,” he said, “but for that serpent, ‘Nea,’ the puma, would have brought in some fresh meat. As it is, I have had to share with her even the small amount of tinned food we happened to have left here.”

The flying pieces of rock that had injured him had broken his rifle; and he had only a few cartridges for his revolver.

“It’s all been unfortunate,” he said. “They put all the things in the wrong cave, and, when I came to myself after my desperate race between the falling rocks, I was in darkness and the puma was licking my hands and face. With much difficulty I found my way to the front here and pulled the stone away; then found a lantern and some oil, and got a light. The entrance to the canyon I found was all dark—buried—and I could still hear rumblings as of further falls of rock; but they sounded distant. I imagine, therefore, that the valley must be buried pretty deep. I set about making myself as comfortable as I could; and, when I put the ladder out, ‘Puss,’ as I call her, went out hunting while I bathed my ankle and arm. Several days she went out and brought in something pretty regularly, and I thought I should be able to nurse myself up and get well enough to struggle through the wood alone. But, one morning, she refused to go out; that day I had a visit from a pack of ‘Warracaba tigers’; another time when she stayed in, looking out myself, I saw that awful serpent hanging from a bough; and there it has been day and night ever since; ‘Puss’ refusing to venture forth. I fired all my cartridges, except two, at it without any effect. It kept ceaselessly swaying its head about, and my arm pained me and my hand trembled; and, unless you can put a bullet through its head, it’s of no use firing at a creature like that, you know. If my rifle had been all right, the thing would have been easy enough. I kept two cartridges in reserve—one for poor ‘Puss’ and the other for myself—and I think you came only just about in time to save us both.” And Jack’s voice shook, and he felt a choking sensation in his throat. It was clear he had given up hope and had been making up his mind to face death alone.
