I passed the mouth of the Big Horn in mid-forenoon of the following day. I should have liked to land but was fearful I would get out of hand and take too much time once I turned myself loose at the one point above all others where the most Yellowstone history has been made. The Big Horn was known in a vague way through the Indian accounts of it even before the time of Lewis and Clark, but the first permanent establishment upon it was the trading post which Manuel Lisa erected there in 1807. It was to this point that John Colter fled after being chased by the Blackfeet across Yellowstone Park, and it was his point of departure in a canoe on a voyage to St. Louis which he claimed to have made in thirty days. Colter's account of how he ran down several black-tail deer and bighorn before relaxing the tremendous burst of speed he had put on to distance the Redskins never bothered me much, but that average of close to a hundred miles a day—most of it down the languid Missouri—somehow won't stick. I found I couldn't keep it up even after I put on my engine. Colter undoubtedly exaggerated about his time on this trip, and that being true, doubtless, also, about trampling underfoot the deer and bighorn. Colter was a liar but not an artistic one. Now if old Jim Bridger had been telling that canoe-voyage yarn he would doubtless have hung a bag of alum over the bow and shrunk the distance as a starter, and then probably used a trained catfish for auxiliary power. That's the kind of liar that makes the world safe for democracy.

Post after post was founded at the confluence of the Yellowstone and Big Horn until, in the 'seventies, it became the centre of operations for the Army in the greatest of our Indian wars. In comparison with the broad, rolling tide of the Yellowstone the turbid current of the tributary appeared shallow and of no great volume—the last place in the world for a river steamer to venture with any hope of going its own length without grounding. And yet, I reflected, the Big Horn could have been scarcely higher on that sultry Sunday of June 25th, 1876, when Captain Grant Marsh, acting on orders from General Terry, sparred and warped and crabbed the wonderful old Far West up twenty-five miles of those rock-choked, foam-white rapids. The skies to the south were black with rolling smoke clouds, but with nothing to indicate that under their shadows five companies of the 7th Cavalry were paying with their lives for the precipitancy of their brave but hot-headed commander. The next day the Far West reached, passed and returned to the mouth of the Little Big Horn, and it was there that a half-crazed Crow scout, all but speechless with terror, brought on the first lap of its way to the outer world the story of the Custer Massacre.

On the morning of June 30th, with Major Reno's wounded aboard, the Far West cast off for the start of her epic run to Fort Lincoln. Major Joseph Hanson records that that Captain Marsh all but collapsed in the pilot-house as the terrible responsibility of that fifty-three-mile run down the rock-paved channel of the Big Horn suddenly assailed him on stepping to the wheel. General Terry had just said to him: "Captain, you have on board the most precious cargo a boat ever carried. Every soldier here who is suffering with wounds is the victim of a terrible blunder; a sad and terrible blunder." Crabbing up stream with supplies was one thing, floundering down with a shattered human cargo of that kind, quite another. Captain Marsh declared the moment the most sickening of his life. Then he pulled himself together and drove her through. I tried to imagine the relief her skipper must have felt as he rounded that last bend above where I now saw a railway bridge and headed the Far West into the deep, clear channel of the Yellowstone, but couldn't come near to compassing it. A man has to have carried a load of that kind to know what it means to put it down. The Far West broke all upper river records for speed in her run to Fort Lincoln, below Bismarck, the nearest hospital. Captain Marsh's splendid achievement in saving Reno's wounded by his masterly navigation is the one bright bit of silver lining on the sodden black cloud of the Massacre of the Little Big Horn.

At the mouth of the Rosebud I passed another important rendezvous of the Sioux campaign. From here, after taking his final orders from General Terry, Custer had departed on the march that was to finish upon the Little Big Horn. Major Hanson relates an incident that occurred here an hour or two after the ill-fated command had disappeared up the valley, and which was particularly interesting to me at the moment as it involved the upset of a skiff in a riffle I was about to run. All of the letters written by Custer's men since leaving Fort Lincoln were put in a bag and started by boat for Fort Buford. "Sergeant Fox and two privates of the escort were detailed to carry the precious cargo down," wrote Major Hanson. "Amid a chorus of hearty cheers from the people on the steamer, they started out. But they were totally unfamiliar with the handling of a small boat in the swirling current of the Yellowstone. Before they had gone fifty feet their skiff overturned. There, in full view of all their comrades, who could not reach them in time to save, all three of the unfortunate fellows sank from sight, while the mail sack went to the bottom of the river."

The soldiers were drowned, but persistent dragging of the river under the direction of Captain Marsh finally brought up the mail sack, thus saving for their relatives and friends the last letters of the men who were to fall before the Sioux a few days later. These included Custer's note to his wife as well as young Boston Custer's letter to his mother. Sending three inexperienced soldiers to boat down the Yellowstone with so humanly precious a freight in their care cannot but strike one as about on all fours with other blunders that led up to the tragic climax of that disastrous campaign.

I found a shallow bar clawed with sprawling channels but no riffles to speak of below the Rosebud. There could hardly have been bad water there at any time.

Landing at a grassy point to make camp about seven-thirty I found the mosquitos so thick that I beat a hasty retreat to the boat and pushed off again in search of a gravel bar in midstream. The sight of new and comfortable ranch buildings lured me to land a half mile below, however, where an invitation to spend the night in the screened bunk-house was promptly forthcoming. The ranch turned out to be a part of an extensive irrigation enterprise, promoted and managed by a chap named Cummings from Minneapolis, who chanced to be on the place at the time. Except for the general farming depression, prospects were good, he said—better than in the dry farming sections, where crops, already very short, were being still further shortened by grasshoppers. He was rather more optimistic than the run of Montanan pastoralists and agriculturalists I had met, all of whom had been having terribly hard sledding.

A leisurely three-hour's run in the morning brought me to Fort Keogh and Miles City, respectively above and below the Tongue. The red-brown current of the latter tinged the Yellowstone for a mile below their confluence. Clark camped at the mouth of the Tongue, and his painstaking description of the second in size of the Yellowstone's tributaries might have been written today.

"It has a very wide bed.... The water is of a light-brown colour and nearly milk-warm; it is shallow and its rapid current throws out great quantities of mud and some coarse gravel.... The warmth of the water would seem to indicate that the country through which it passes is open and without shade."

Captain Clark was a splendid geographer, even if he did run amuck a bit with his historical nomenclature.
