Once a free trapper came floating down the Missouri with his canoe full of beaver-pelts, which he quickly exchanged for the gay attire to be obtained at Fort Union. Oddly enough, though the fellow was a French-Canadian, he had long, flaxen hair, of which he was inordinately vain. Strutting about the court-yard, feeling himself a very prince of importance, he saw MacKenzie's pretty young Indian wife. Each paid the other the tribute of adoration that was warmer than it was wise. The _dénouement_ was a vision of the flaxen-haired Siegfried sprinting at the top of his speed through the fort gate, with the irate MacKenzie flourishing a flail to the rear. The matter did not end here. The outraged Frenchman swore to kill MacKenzie on sight, and haunted the fort gates with a loaded rifle till MacKenzie was obliged to hire a mulatto servant to "wing" the fellow with a shot in the shoulder, when he was brought into the fort, nursed back to health, and sent away. At another time two Rocky Mountain trappers built an opposition fort just below Union and lay in wait for the coming of the Blackfeet to trade with the American Fur Company. MacKenzie posted a lookout on his bastion. The moment the Indians were descried, out sallied from Fort Union a band in full regalia, with drum and trumpet and piccolo and fife--wonders that would have lured the astonished Indians to perdition. Behind the band came gaudy presents for the savages, and what was not supposed to be in the Indian country--liquor. When these methods failed to outbuy rivals, MacKenzie did not hesitate to pay twelve dollars for a beaver-skin not worth two. The Rocky Mountain trappers were forced to capitulate, and their post passed over to the American Fur Company.
