To my horror and consternation it was answered by a savage yell, and something charged out nearly to the fire but dashed back directly, so quickly, indeed, that we had no time to get more than a sharp shot apiece at the fierce creature.

“Load again quickly,” whispered the doctor; and I obeyed him, listening the while to the rustling crackling noise at a little distance.

“Do you think we hit it?” I said softly. I was afraid to speak aloud lest it should bring down a charge upon us.

“I’m afraid not,” he replied, as he reloaded and then stood scanning the edge of the circle of light formed by the fire’s glow.

There was nothing visible but what seemed to be a dark opening amongst the trees, through which it appeared to me that our enemy must have passed.

Then we waited, watching so excitedly for the next attack that the fire was for the moment forgotten. Then, seeing the glow it cast become less, we both seized upon armfuls of wood and threw them on, deadening the flame so that the space around was comparatively dark.

That was the most anxious time of all, for, do what we would, the fire sent forth huge volumes of smoke, but would not blaze. At any moment it seemed that the great beast might take advantage of the gloom and spring upon us, and we shook the ends of the burning branches and half-consumed pieces of wood, but in vain. Instead of the light glow there was comparative darkness, and in despair, as if again moved by the same impulse, we ceased troubling about the fire, and stood with hand on trigger, ready to pull at the first chance.

Then all at once there was a vivid tongue of flame cutting right through the thick smoke, another and another, and I uttered a sigh of relief as the heap of smouldering boughs and leaves burst once more into a blaze.

“Now while the light lasts let’s have a good shot at the brute,” said the doctor, speaking as if nerved to desperation by the torture under which we both writhed. “I’m going to kneel here, Joe; you walk on, and that will make the tiger, or whatever it is, show itself in watching you.”

“It isn’t a tiger,” I whispered. “I caught sight of it, and it looked more like a man.”
