In 1861 the heroic _Chippewa_ made her last trip up the river. Again bound for Fort Benton, she reached the end of her voyage and of her career at a point a little below the mouth of Poplar River, Mont., since known, from this connection, as Disaster Bend. She was loaded with American Fur Company goods and Blackfeet annuities, and had a goodly quantity of alcohol on board. One Sunday evening in the month of May, while supper was being served, the boat was discovered to be on fire. She was immediately run ashore, the passengers were put off, and she was set adrift to avoid the danger from an expected explosion of gunpowder that was in the hold. The boat floated across the river and about a mile downstream, when she blew up, just as the upper works were fairly consumed to the water’s edge. The explosion was terrific, and packages of merchandise were found at a great distance from the place. No lives were lost, and the personal effects of the passengers were saved. The fire was caused by some deckhands, who went into the hold with a lighted candle to steal some liquor. CHAPTER XIX. FORT BENTON. Few, if any, towns in the Far West country possess so unique and varied a history as Fort Benton. With the exception of some of the old Spanish villages in the southwest it is the oldest settlement in the mountain country, for the traders made their first establishment there in 1831. The true historic career of Fort Benton did not embrace more than half a century, yet in that brief space it saw more of romance, tragedy, and vigorous life than many a city of a hundred times its size and ten times its age. [Sidenote: OPENING TRADE WITH THE BLACKFEET.] The commercial importance of Fort Benton arose, of course, from its situation at the head of navigation on the Missouri River; but this was not the cause of its first location there. The surrounding country was the home of the Blackfeet Indians--great fur producers, but in early times inveterate enemies of the whites. From the time when the traders began to penetrate those distant regions it was their ambition to open up trade relations with this fierce and refractory tribe. Attempts were made in the years 1807–10 and again in 1822–23, but wholly without success. The Indians always evinced a deadly hostility, attacked the trappers, killed a great many, drove them out of the country, and gave them no opportunity to explain their pacific purposes.
