"Maybe the spalpeen's hidin' in the little cave where ye laid down yer gun," suggested Barney, going towards the place as he spoke. "Och, then, come here, friend; sure it must be the mouth of a mine, for there's two o' the beautifulest di'monds I iver—"

Barney's speech was cut short by a low peculiar sound, that seemed like the muttering of far-distant thunder. At the same moment the hermit pulled him violently back, and, placing himself in a firm attitude full in front of the cavern, held the point of the spear advanced before him.

"Martin," he whispered, "shoot an arrow straight into that hole,—quick!"

Martin obeyed, and the arrow whizzed through the aperture. Instantly there issued from it a savage and tremendous roar, so awful that it seemed as if the very mountain were bellowing and that the cavern were its mouth. But not a muscle of the hermit's figure moved. He stood like a bronze statue,—his head thrown back and his chest advanced, with one foot planted firmly before him and the spear pointing towards the cave. It seemed strange to Martin that a man should face what appeared to him unknown danger so boldly and calmly; but he did not consider that the hermit knew exactly the amount of danger before him. He knew precisely the manner in which it would assail him, and he knew just what was necessary to be done in order to avert it; and in the strength of that knowledge he stood unmoved, with a slight smile upon his tightly compressed lips.

Scarcely had the roar ceased when it was repeated with tenfold fierceness; the bushes and fern leaves shook violently, and an enormous and beautifully spotted jaguar shot through the air as if it had been discharged from a cannon's mouth. The hermit's eye wavered not; he bent forward a hair's-breadth; the glittering spear-point touched the animal's breast, pierced through it, and came out at its side below the ribs. But the force of the bound was too great for the strength of the weapon: the handle snapped in twain, and the transfixed jaguar struck down the hermit and fell writhing upon him!

In the excitement of the moment Barney drew his pistol from his belt and snapped it at the animal. It was well for the hermit at that moment that Barney had forgotten to prime his weapon; for, although he aimed at the jaguar's skull, there is no doubt whatever that he would have blown out the hermit's brains. Before he could make a second attempt, Martin sprang towards the gun which leaned against the cliff, and, running quickly up, he placed the muzzle close to the jaguar's ear and lodged a bullet in its brain. All this was done in a few seconds, and the hermit regained his legs just as the animal fell dead. Fortunately he was not hurt, having adroitly avoided the sharp claws of his enemy.

"Arrah! Mister Hermit," said Barney, wiping the perspiration from his forehead, "it's yersilf that was well-nigh done for this time, an' no mistake. Did iver I see sich a spring! an' ye stud the charge jist like a stone wall,—niver moved a fut!"

"Are you not hurt?" inquired Martin, somewhat anxiously; "your face is all covered with blood."

"Yes, boy, but it is the blood of the jaguar; thanks to you for your quick hand, I am not hurt at all."

The hermit washed his face in the neighbouring brook, and then proceeded to skin the jaguar, the carcase being worthless. After which they retraced their steps through the woods as quickly as possible, for the day was now far spent, and the twilight, as we have before remarked, is so short in tropical latitudes that travellers require to make sure of reaching the end of the day's journey towards evening, unless they choose to risk losing their way, and spending the night in the forest.
