“You would have made haste too, friend Seth,” said Ernest, laughing—there never was such a fellow to laugh as he was—“if you had heard what I have about those blessed Indians, and our old acquaintance, Rising Cloud.”

“What is that?” asked Mr Rawlings anxiously, who had just come up in time to catch the last observation of the young engineer—“what have you heard about Rising Cloud?”

“Only,” said Ernest, and he spoke gravely enough now—“that he is spreading murder and havoc all along the banks of the Missouri, and may be soon here upon us with the miscreant gang he leads. I heard terrible tales of him in the steamer I came down the river in. The captain of the little craft told me that the Indians had burnt every outlying settlement in Southern Dakota, massacring all the white inhabitants, and were making their way northwards, so we’d better look out. Why, he said they’d even attacked his boat when it was at one of the landings; and if he hadn’t put on steam he and his vessel would have been settled, with all on board.”

“Ah,” said Mr Rawlings, “that corroborates the warning we got from the commander of the United States troops at Fort Warren when you were away. We certainly must keep a careful look now, for it would not do to repeat all of my poor Cousin Ned’s experiences, and have the result of our toil snatched from our grasp by those relentless fiends of the prairie when it was just within our reach, as it was in his, poor fellow!”

Mr Rawlings then went on to tell Ernest what they had heard, and give an account of what had transpired during his absence at the settlements; after which the whole party proceeded to examine their defences in detail, the young engineer suggesting that they should entrench the camp in a systematic way, and also the machinery which would be erected on the river’s bank.

There were but two directions from which they could be attacked; for the precipitous range of the Black Hills, standing behind Minturne Creek with its semicircular rampart, protected their rear and sides, so that they had only their front face to guard, along the course of the stream, following the gulch.

The same safeguards which they had adopted before were redoubled in the face of the second warning they received by the account Ernest Wilton brought back with him of the Indian savages in their neighbourhood, their day and night watch being maintained with the strictest regularity.

The teams were soon unloaded and started on their return journey, and with the exception of the men engaged in clearing out the quartz from the mine, all hands set to to erect the water-wheel and stamps, which operation, as all the pieces of timber were fitted and numbered, was an easy and rapid one.

In three weeks afterwards all was ready for a start. Five hundredweight of quartz was then weighed out and carried down to the stamps, the gear which connected the machinery with the great wheel which was revolving in the river was connected, and the stamps began to rise and fall with a heavy regular rhythm.

The quartz was thrown in beneath the stamps shovelful by shovelful, and in an hour and a half the last fragment was used up. For another half hour the stamps rose and fell, then the water running through them was no longer milk-white, and the stamps were stopped. Then the blankets spread upon the ways by which the mud-charged gold had flowed were taken up and washed, the quicksilver was taken out of the concentrators and passed through wash-leather bags, in which great rolls of amalgam remained. These were placed in large crucibles to drive off the quicksilver, and then removed from the furnace and the gold placed in the scale. To this was added the fine gold from the blankets. Ernest Wilton added the weights, and around him stood Mr Rawlings and all the miners off duty.
