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.
