Two loud roars, as if from a brazen trumpet, were heard at the moment. They appeared to proceed from the same point, proving that the jaguars had joined company; and, moreover, proclaimed the joy which the fierce creatures felt at the darkness being restored. This was further evident from their repeated sniffing of the air, like horses who afar off scent with delight the fresh emanations of the water.

At this the two trappers, leaving the party by the fire, betook themselves to the cistern. The moon, for a moment shining out, glanced upon the barrels of their long rifles; but the next moment they had disappeared behind the ridge that surrounded the spring.

No doubt it is a grand pleasure to witness the spectacle of a bull-fight, as the huge bull dashes into the ring, and, pierced by the tormenting bandrilleros, with a crest erect, and eyes flashing fire, bounds over the arena. But, if the spectators were not separated from the actors by an impassable barrier, the sight would have in it less of enjoyment than of terror. The combats between men and tigers—which the Romans used to enjoy—must have been a still more exciting spectacle; but who can doubt that, if the iron railing which separated the audience from the combatants had been removed, scarce one of the former would have remained in the circus to witness the sanguinary struggle?

Only a short space—not wider than a jaguar could have passed over in a single leap—here separated the spectators from the actors in the drama about to be enacted. Supposing, then, that one of the actors should fail in performing his part, and the spectators have to take his place? Here was a situation, exceptional, and fertile in emotions, which most of the travellers felt keenly at the moment.

Meanwhile the trappers had descended into the little crater-like valley of the spring, and there placed themselves in readiness, rifle in hand, to await the approach of their terrible adversaries. They were both upon their knees, back to back, in order that they could keep at the same time under view the whole circumference of the circle. Both had placed their knives in readiness, in case that, by any chance, they should either miss their aim, or—what would be almost as unlucky—only wound the enemy; for they well knew that a wounded jaguar is a more dangerous adversary than one that escapes altogether from the touch of the bullet.

Fortunately the moon had again appeared; but being yet low down in the sky, her beams were not thrown into the bottom of the valley—and therefore the trappers themselves were still under the shadow. This circumstance was in their favour.

Notwithstanding the perilous position in which they had thus voluntarily placed themselves, neither made the slightest movement; and the long barrels of their rifles stood forth in front of them, as motionless as bronze cannon set in battery.

They well knew, in case either should miss with their firearms, that a hand-to-hand struggle with the ferocious tigers would be the result; a combat of knives and claws—a combat to the death. Yes; at the bottom of that little valley it would be necessary for them to conquer or die. They knew this without exhibiting the slightest show of fear.
