About a minute after that the Mahatma stopped and let King draw abreast; then, continuing to swing the lantern he started forward again. I don't know whether it was fear, intuition, or just curiosity that made me wonder why he should change the formation in that way, but quite absurdly I deduced that he wished King to walk into a trap. It was that that saved me.
"Look out, King!" I warned.
Exactly as I spoke I set my foot on a yielding stone trap-door—felt a blast of cool air—and heard water unmistakably. The air brought a stagnant smell with it. I slid forward and downward, but sprang simultaneously, managing to get my fingers on the edge of the stone in front. But the balanced trap-door, resuming its equilibrium, caught me on the back of the head, half-stunning me, and in another second I would have gone down into the dark among the alligators. I just had enough consciousness left to realize that I was hanging over the covered end of the alligator tank.
But the faint outer circle of light cast by the Mahatma's lantern just reached me, and as King turned his head to acknowledge my warning he saw me fall. He sprang back, and seized my wrists, just as my fingers began slipping on the smooth stone; but my weight was almost too much for him, and I came so near to dragging him through after me that the stone trap got past my head and jammed against my elbows.
Then I heard King yelling for the Mahatma to bring the lantern back, and after what seemed an interminable interval the Mahatma came and set one foot on the stone, so that it swung past my head again, nearly braining me in its descent. I don't know whether he intended that or not.
"There is more in this than accident," he said, his voice booming hollow as he bent to let the light fall on me. "Very well; pull up your buffalo, and you shall have him!"
It was no easy task for the two of them to haul me up, because the moment the Mahatma removed his foot from the lid of the trap the thing swung upward and acted like the tongue of a buckle to keep me from coming through. When he set his foot on it again, the other foot did not give him sufficient purchase. Finally King managed to pull his loin-cloth off and pass it around under my armpits, after which the two together hauled me clear, minus in the aggregate about a half square foot of skin that I left on the edge of the stone.
Off the Mahatma went alone again, swinging his lantern, and apparently at peace with himself and the whole universe.
Thereafter, King and I walked arm-in-arm, thinking in that way to lessen the risk of further pitfalls. But there was no more. The Mahatma reached at last what looked like a blind stone wall at the end of the tunnel; but there was a flagstone missing from the floor in front of it, and he disappeared down a black-dark flight of steps.
We followed him into a cellar, whose walls wept moisture, but we saw no cobras; and then up another flight of steps on the far side into a chamber that I thought I recognized. He disappeared through a door in the corner of that, and by the time we had groped our way after him he was sitting in the old black panther's cage with the brute's head in his lap, stroking and twisting its ears as if it were a kitten. The cage door was wide open, and the day was already growing hot and brassy in the east.
