"But why interesting?"
"For one reason, there is no actual necessity for the natives to make a well-worn path to the brook, as plenty of water can be had in the village; for another, I think we have stumbled on some secret place where these savages hold their religious ceremonies. I am not sure, mind you, but the circumstances point that way."
The path descended abruptly into what appeared to be a vast circular hollow, though the dense clusters of trees and bushes prevented us from seeing the opposite side of the rock-bound circle. The stream now became a rushing torrent, leaping from rock to rock in a series of spray-fringed cascades, and the only sound that broke the silence of the spot was the noise of the falling water.
"This must have been the crater of an active volcano at one time," said the doctor in a low tone, as if influenced by the solitude of the spot. "I think we'll find I am right about the outlet of the stream."
At length we reached the bottom of the vast cavity, and in the unaccustomed twilight caused by the foliage and the overhanging rocks (though it was still broad daylight) we could see a large pool of dark water, and, surrounding this lakelet, were a number of posts, each about six feet in height, and most of them were surmounted by a grinning skull, while a fetid atmosphere hung over the place like a pall.
I felt the colour leave my face at the horror of the sight, and, glancing at the doctor, I noticed that his jaw was firmly set and his eyebrows knitted in grim determination. Yadillah, though used to scenes of cruelty in his younger days, turned an ashy grey, and I heard him mutter a sentence in which the word "Allah" caught my ear.
"What does it mean?" I whispered.
"They are the skulls of men killed in tribal fights, to take the mildest view of the situation," replied Dr. Conolly. "But I should not be surprised if this is the scene of gruesome practices of cannibalism."
"Come on, let's get away from this horrible place," I exclaimed.
"One moment," he replied, and, picking up a piece of stone, he threw it into the pool, which, although it obviously was fed by the stream, was absolutely unruffled on its surface.
