"I decided to go, and the terms were agreed upon. We set out from Auckland, the five of us, a week later. We went by coastal steamer to a little port in the Bay of Plenty, and there we plunged into the Urewera Mountains. My companions thought of nothing but the search for the source of the golden sands, but I was interested only in the ruby rock. There lay the fortune, if I could find it. I carried the specimen of corundum in my waistcoat pocket. "The river we were ascending to its source was called the Araheoa. It was a rushing, noisy torrent, winding along a deep and narrow gorge, which in places almost met overhead. Some patches of olivine and serpentine encouraged me to think that we should find a heavy belt of the rock somewhere along the upper part of the valley, but my hopes were not realized. Day after day passed, and I found no more of it. When my companions washed the sands of likely stretches of river beach for fine gold, I examined the waste for corundum crystals, but I found no signs of them. "We followed the river until we reached an inaccessible mountain gorge which seemed to bar our further progress. But, by diverting our course some miles to the northward, we were able to ascend to the upper reaches of the river, and, here, to my delight, I found the banks and rapids studded with great green masses of olivine rocks. "I was anxious to examine these rocks, which extended up the mountain side, and my companions agreed with me that it was advisable to leave the bed of the river for the spur of the mountains where the river apparently took its rise. We crossed the stream, and commenced a gradual but oblique ascent of the spur. But after climbing for some hours we found our further progress stopped by a wide and deep gully, a sinister place, full of masses of dark green rocks. At the foot of one of the largest of these rocks we came across a large hole descending almost perpendicularly into the earth. "We lit our lamps and descended. After some scrambling we found ourselves on a landing-place, from which another low passage of an easier gradient led into a large cave in the solid rock. "The surface underneath our feet was covered with a dust so fine that it slipped from beneath us like sand, and rose in thick clouds about us. The cave was high enough to walk upright in, and seemed to run a great distance, with many lateral passages and smaller recesses off the principal chamber. Moynglass entered one of these passages and disappeared from view. A few moments afterwards we heard him, in a very excited voice, calling us to follow him. "We proceeded stooping, in Indian file, down the passage, and found Moynglass in a smaller cave at the end of it, staring intently at something which was at first difficult to see in the gloom. Then, by the light of our lamps, we made out a sapling sticking up between two rocks, with a withered human hand impaled on it by a rusty sheath knife.
