After having reposed for about an hour, we pushed on slowly up the ravine, and had gone no great way before we heard a succession of tremendous yells. At length we reached what might be called the surface of the ground; for our path hitherto, since leaving the platform, had lain beneath an archway of high rock and foliage, at a vast distance overhead. With great caution we stole to a narrow opening, through which we had a clear sight of the surrounding country, when the whole dreadful secret of the concussion broke upon us in one moment and at one view. The spot from which we looked was not far from the summit of the highest peak in the range of the soapstone hills. The gorge in which our party of thirty-two had entered ran within fifty feet to the left of us. But, for at least one hundred yards, the channel or bed of this gorge was entirely filled up with the chaotic ruins of more than a million tons of earth and stone that had been artificially tumbled within it. The means by which the vast mass had been precipitated were not more simple than evident, for sure traces of the murderous work were yet remaining. In several spots along the top of the eastern side of the gorge (we were now on the western) might be seen stakes of wood driven into the earth. In these spots the earth had not given way; but throughout the whole extent of the face of the precipice from which the mass _had_ fallen, it was clear, from marks left in the soil resembling those made by the drill of the rock-blaster, that stakes similar to those we saw standing had been inserted, at not more than a yard apart, for the length of perhaps three hundred feet, and ranging at about ten feet back from the edge of the gulf. Strong cords of grape vine were attached to the stakes still remaining on the hill, and it was evident that such cords had also been attached to each of the other stakes. I have already spoken of the singular stratification of these soapstone hills; and the description just given of the narrow and deep fissure through which we effected our escape from inhumation will afford a further conception of its nature. This was such that almost every natural convulsion would be sure to split the soil into perpendicular layers or ridges running parallel with one another; and a very moderate exertion of art would be sufficient for effecting the same purpose. Of this stratification the savages had availed themselves to accomplish their treacherous ends. There can be no doubt that, by the continuous line of stakes, a partial rupture of the soil had been brought about, probably to the depth of one or two feet, when, by means of a savage pulling at the end of each of the cords (these cords being attached to the tops of the stakes, and extending back from the edge of the cliff), a vast leverage power was obtained, capable of hurling the whole face of the hill, upon a given signal, into the bosom of the abyss below.
