When we had reached the face of the cliff, instead of sinking a shaft I determined on carrying a gallery down an incline, keeping the rock as a wall on my right, till I reached the bottom of all.

The advantage of making an incline was that there was no hauling up of the earth by a bucket let down over a pulley, and it was easier for myself to descend.

I had not made my tunnel wide enough, and it was tortuous. When I began to sink, I set two of the men to smash up the masses of fallen chalk rock, so as to widen the tunnel, so that I might use barrows. I gave strict orders that all the material brought up was to be picked over by two of the most intelligent of the men, outside in the blaze of the sun. I was not desirous of sinking too expeditiously; I wished to proceed slowly, cautiously, observing every stage as we went deeper.

We got below the layer in which were the relics of the Bronze Age and of the men of polished stone, and then we passed through many feet of earth that rendered nothing, and finally came on the traces of the reindeer period.

To understand how that there should be a considerable depth of the débris of the men of the rude stone implements, it must be explained that these men made their hearths on the bare ground, and feasted around their fires, throwing about them the bones they had picked, and the ashes, and broken and disused implements, till the ground was inconveniently encumbered. Then they swept all the refuse together over their old hearth, and established another on top. So the process went on from generation to generation.

For the scientific results of my exploration I must refer the reader to the journals and memoirs of learned societies. I will not trouble him with them here.

On the ninth day after we had come to the face of the cliff, and when we had reached a considerable depth, we uncovered some human bones. I immediately adopted special precautions, so that these should not be disturbed. With the utmost care the soil was removed from over them, and it took us half a day to completely clear a perfect skeleton. It was that of a full-grown man, lying on his back, with the skull supported against the wall of chalk rock. He did not seem to have been buried. Had he been so, he would doubtless have been laid on his side in a contracted posture, with the chin resting on the knees.

One of the men pointed out to me that a mass of fallen rock lay beyond his feet, and had apparently shut him in, so that he had died through suffocation, buried under the earth that the rock had brought down with it.

I at once despatched a man to my hotel to fetch my camera, that I might by flashlight take a photograph of the skeleton as it lay; and another I sent to get from the chemist and grocer as much gum arabic and isinglass as could be procured. My object was to give to the bones a bath of gum to render them less brittle when removed, restoring to them the gelatine that had been absorbed by the earth and lime in which they lay.

Thus I was left alone at the bottom of my passage, the four men above being engaged in straightening the adit and sifting the earth.
