The hospitable Captains were more than glad to entertain visitors. They were there to cultivate international amity.

In their hearts Lewis and Clark never dreamed what a commotion that friendly letter to Chaboillez had stirred up. It had gone far and awakened many. Immediately upon its receipt Chaboillez sent out a runner.

"Lewis and Clark with one hundred and eighty soldiers have arrived at the Mandan village," so the story flew. "On their arrival they hoisted the American flag and informed the natives that their object was not to trade, but merely to explore the country; and that as soon as navigation shall open they design to continue their route across the Rocky Mountains to the Pacific. They have made the natives a few small presents and repaired their guns and axes free. They have behaved honourably toward my people, who are there to trade with the natives."

Such a message as this was enough to bring Alexander Henry down to investigate. The cottonwood fires at Fort Mandan roared up the chimneys with unwonted splendour that winter night. The thermometer suddenly fell to forty-five degrees below zero; but warm and comfortable beside the blaze they talked, American and British, in this border of the nations.

Charles Mackenzie had been a clerk of the Northwest Company for a year. Of the same rank as himself was Larocque, and both were popular with the redmen. In fact, Mackenzie, a Scot from the Highlands, was already married to an Indian girl, and Larocque was a Frenchman. That was enough. No nation fraternized with the redmen as the Frenchmen did.

Alexander Henry, fur trader among the American Indians and one of the famous Northwesters, bore a great name in the north. There were two Alexander Henrys; the younger was a nephew of the other, and he it was that had now come to visit Lewis and Clark. He knew more of the country than, perhaps, any other man in the northwest. In fact, his uncle, the elder Henry, was at Michilimackinac in the days of Pontiac, and had penetrated to the Saskatchewan before ever there was a Northwest Company.

Henry, Jr., wintered on the Red River the very year that Alexander Mackenzie crossed the continent,—1793. As a bourgeois of the Northwesters, with a fleet of canoes and twenty-one men he had led the Red River brigade of 1800 up into the Winnipeg country.

The scarlet belts, breeches of smoked buckskin, and blue cloth leggings of Alexander Henry's old coureur des bois were known for hundreds of miles.

Yes, he knew the Sioux. Their pillaging bands sometimes plundered his traders. "They are not to be trusted," he declared in positive tone.

"A very sensible, intelligent man," said Lewis and Clark to themselves as the great Northwester talked of the country and the tribes.
