At that period popular rumour credited the Black Hills with concealed wealth to a fabulous extent. Gold had already been found there, not in any great quantities, but still it had been found, and the nature and formation of the soil pointed to its existence in vast veins, at least so said popular rumour. That was enough. Men began to flock to this new Eldorado. Parties of prospectors and miners found their way to its sequestered valleys, and soon the rocks rang to the sound of the pick, and the mountain streams which gurgled through its savage solitudes were fouled with the washing of panned dirt. But the miners had two factors to reckon with--the Government and the Indians. The former was bound by treaty to keep white men, particularly miners, out of the Indian reservation; the latter became more and more discontented over the non-fulfilment of the agreement. The shrewd tribesmen knew that gold was even a greater enemy to their race than rum. The discovery of gold meant an incursion of whites; first a few, then thousands; cities, towns, machinery. Then good-bye to the game, whereby they largely subsisted; good-bye, indeed, to the country itself, as far as they were concerned. They threatened war. It became necessary for something to be done. Troops were sent to patrol the Black Hills, with strict injunctions to arrest all white men and send them under guard to the settlements. This was extensively done. But the expelled miners, watching their chance, lost no time in slipping back again, and their numbers, so far from decreasing, had just the opposite tendency, arrests notwithstanding. Then the United States Government resolved to purchase the Black Hills, and made overtures to the Sioux accordingly. The latter were divided in opinion. Some were for terms, the only question being as to their liberality; others were for rejecting the proposal at any price, and if the Government still persisted in its neglect to keep out the white intruders, why then they must take the defence of their rights into their own hands. Pause, O philanthropic reader, ere running away with the idea that these poor savages' rights were being ruthlessly trampled on; and remember the old legal maxim about coming into court with clean hands. The Government tried to do its best, but in a vast, rugged, and lawless country the inhabitants are not to be policed as in a well-ordered city of the Old World. Men could not be hung merely for encroaching on the reservation, and the state of popular feeling precluded any sort of deterrent punishment. And then, were the Indians themselves strictly observing their side of the treaty? Let us see.
