“And you started right back to find us?” cried Walter.

“I rested a while first, but I could not sleep. M’sieu Renville gave me a fresh horse, and these men offered to come with me. I thought you would follow our trail. If I kept to it, I would find you; if le Murrai had not overtaken you.”

The bois brulés from the trading post gladly gave up their horses to the weary boys, and went afoot. So Lake Traverse and the shelter of the Columbia Fur Company’s fort was reached at last. There, in one of the log buildings within the stockade on the shore of the lake, the rest of the little party were waiting anxiously. The boys, almost dropping from their saddles with sleep and weariness, were embraced and shaken by the hand, and cried over, and questioned, until the trader, Joseph Renville, intervened. He led them away to bunks where they could sleep undisturbed for as many hours as they cared to.

When the boys had had their sleep out, the two sections of the party exchanged stories. Afterwards Duncan McNab had something to add. He had returned to the Indian camp two nights before to find the dance in full swing. Within the medicine lodge, Murray was instructing the chosen initiates in some sort of mystic rites. From time to time one of them would come out to chant or howl a few words or syllables and to go through the steps and posturings of the new dance. The men around the fires would repeat the lesson over and over, until another of the chosen ones appeared to teach them something new.

“As near as I could mak oot,” said Duncan, “it was something like the medicine dance the Mdewakanton Dakota on the Mississippi mak ta their god Unktahi, that Murray was teachin’ yon Wahpetons, but he was puttin’ in some stuff of his ain. Some o’ the words o’ the sangs soundit like Gaelic, but made na sense as far as I could ken, an’ I hae a bit o’ the Gaelic mysel. I’m thinkin’ he picked the words for their mysterious sound like.”

When the excitement had reached the right pitch, Murray began to serve out liquor. “I dinna ken where he got sa mickle,”—McNab shook his head. “He had a cairt loadit wi’ goods an’ kegs an’ what a’. He must be in wi’ ither free traders, some o’ the men on the Missouri most like, or mayhap he stole the stuff fra them. It’s the wrang time o’ year ta be buyin’ furs. It was the good will o’ the sauvages an’ power ower ’em he was after, sa they’d be sure an’ bring him their next winter’s catch.”

As the liquor flowed more freely, the performance grew frenzied. It was a wild night in Tatanka Wechacheta’s village, and McNab spared his listeners the details. He feared every moment that the Indians would raid the neighboring camp, and discover too soon that the white men had gone. But the Black Murray overdid the celebration. He supplied liquor so lavishly that his followers were soon entirely overcome by it. Perhaps he dared not try to withhold what they knew he had. And he failed to curb his own immoderate thirst, but overindulged until, inert in the medicine lodge, he slept as heavily as they. “I’m thinkin’ it was the rascal’s owerfondness for minnewakan that saved a’ your lives,” said McNab. “If he hadna slept sa late, he wad sure hae owertaken the lads on foot an’ maybe the rest o’ ye.”

When Murray finally roused himself, in ugly mood, he gathered together eight or ten reckless young braves who could still sit their horses, and started for the white men’s camp. Up to that time McNab had not felt himself in any great danger, as long as he kept to his own lodge. He was a man of influence among the Dakotas, and back of him was the authority of the Columbia Fur Company and of Joseph Renville. Renville himself was half Dakota and powerful and respected among his mother’s people. But the young chief, still partially drunk, was in almost as savage a mood as Murray that morning, and McNab did not know what might happen.

As soon as Murray had gone, McNab took his leave. On the other side of a tiny clump of trees, he threw his buffalo robe over his horse and himself, hoping that, seen from behind, horse and rider might be taken for a lone bull. He made for the head of the coulee, intending to follow the fugitives and lend his aid if they were attacked. Finding that Murray and his men were coming, he urged his horse to its best speed, to get across the Bois des Sioux before them.

After he had sent the boys on their way, McNab remained to watch the outcome of the fight. It was soon over. The fall of Murray had struck panic into the hearts of his followers. “There was reason for that,” Duncan explained. “Yon Wahpetons are na cowards, but Wechacheta’s chief medicine man was against Murray. The auld fellow claimed Murray was na medicine man at a’ an’ had na wakan or tonwan, na magic powers. When Murray was gatherin’ men ta plunder the white men, the auld man tauld ’em they’d gang ta destruction sure. Murray’s time was come, he said. Afore the sun gaed doon, he wad be deed, an’ likewise a’ that followt him. Sa it was na wonder the young braves was scairt when Murray was shot doon at the ford.”
