Perhaps it was to compensate him for the outlays into which he had been drawn that the colonial minister presently authorized him to embark for Louisiana and pursue his enterprise with that infant colony, instead of Canada, as his base of operations. Thither, therefore, he went; and in April, 1700, set out for the Sioux country with twenty-five men, in a small vessel of the kind called a "felucca," still used in the Mediterranean. Among the party was an adventurous youth named Penecaut, a ship-carpenter by trade, who had come to Louisiana with Iberville two years before, and who has left us an account of his voyage with Le Sueur.[360]
The party slowly made their way, with sail and oar, against the muddy current of the Mississippi, till they reached the Arkansas, where they found an English trader from Carolina. On the tenth of June, spent with rowing, and half starved, they stopped to rest at a point fifteen leagues above the mouth of the Ohio. They had staved off famine with the buds and leaves of trees; but now, by good luck, one of them killed a bear, and, soon after, the Jesuit Limoges arrived from the neighboring mission of the Illinois, in a canoe well stored with provisions. Thus refreshed, they passed the mouth of the Missouri on the thirteenth of July, and soon after were met by three Canadians, who brought them a letter from the Jesuit Marest, warning them that the river was infested by war-parties. In fact, they presently saw seven canoes of Sioux warriors, bound against the Illinois; and not long after, five Canadians appeared, one of whom had been badly wounded in a recent encounter with a band of Outagamies, Sacs, and Winnebagoes bound against the Sioux. To take one another's scalps had been for ages the absorbing business and favorite recreation of all these Western tribes. At or near the expansion of the Mississippi called Lake Pepin, the voyagers found a fort called Fort Perrot, after its builder;[361] and on an island near the upper end of the lake, another similar structure, built by Le Sueur himself on his last visit to the place. These forts were mere stockades, occupied from time to time by the roving fur-traders as their occasions required.
Towards the end of September, Le Sueur and his followers reached the mouth of the St. Peter, which they ascended to Blue Earth River. Pushing a league up this stream, they found a spot well suited to their purpose, and here they built a fort, of which there was great need, for they were soon after joined by seven Canadian traders, plundered and stripped to the skin by the neighboring Sioux. Le Sueur named the new post Fort l'Huillier. It was a fence of pickets, enclosing cabins for the men. The neighboring plains were black with buffalo, of which the party killed four hundred, and cut them into quarters, which they placed to freeze on scaffolds within the enclosure. Here they spent the winter, subsisting on the frozen meat, without bread, vegetables, or salt, and, according to Penecaut, thriving marvellously, though the surrounding wilderness was buried five feet deep in snow.
Band after band of Sioux appeared, with their wolfish dogs and their sturdy and all-enduring squaws burdened with the heavy hide coverings of their teepees, or buffalo-skin tents. They professed friendship and begged for arms. Those of one band had blackened their faces in mourning for a dead chief, and calling on Le Sueur to share their sorrow, they wept over him, and wiped their tears on his hair. Another party of warriors arrived with yet deeper cause of grief, being the remnant of a village half exterminated by their enemies. They, too, wept profusely over the French commander, and then sang a dismal song, with heads muffled in their buffalo-robes.[362] Le Sueur took the needful precautions against his dangerous visitors, but got from them a large supply of beaver-skins in exchange for his goods.
When spring opened, he set out in search of mines, and found, not far above the fort, those beds of blue and green earth to which the stream owes its name. Of this his men dug out a large quantity, and selecting what seemed the best, stored it in their vessel as a precious commodity. With this and good store of beaver-skins, Le Sueur now began his return voyage for Louisiana, leaving a Canadian named D'Éraque and twelve men to keep the fort till he should come back to reclaim it, promising to send him a canoe-load of ammunition from the Illinois. But the canoe was wrecked, and D'Éraque, discouraged, abandoned Fort l'Huillier, and followed his commander down the Mississippi.[363]
Le Sueur, with no authority from government, had opened relations of trade with the wild Sioux of the Plains, whose westward range stretched to the Black Hills, and perhaps to the Rocky Mountains. He reached the settlements of Louisiana in safety, and sailed for France with four thousand pounds of his worthless blue earth.[364] Repairing at once to Versailles, he begged for help to continue his enterprise. His petition seems to have been granted. After long delay, he sailed again for Louisiana, fell ill on the voyage, and died soon after landing.[365]
Before 1700, the year when Le Sueur visited the St. Peter, little or nothing was known of the country west of the Mississippi, except from the report of Indians. The romances of La Hontan and Mathieu Sâgean were justly set down as impostures by all but the most credulous. In this same year we find Le Moyne d'Iberville projecting journeys to the upper Missouri, in hopes of finding a river flowing to the Western Sea. In 1703, twenty Canadians tried to find their way from the Illinois to New Mexico, in hope of opening trade with the Spaniards and discovering mines.[366] In 1704 we find it reported that more than a hundred Canadians are scattered in small parties along the Mississippi and the Missouri;[367] and in 1705 one Laurain appeared at the Illinois, declaring that he had been high up the Missouri and had visited many tribes on its borders.[368] A few months later, two Canadians told Bienville a similar story. In 1708 Nicolas de la Salle proposed an expedition of a hundred men to explore the same mysterious river; and in 1717 one Hubert laid before the Council of Marine a scheme for following the Missouri to its source, since, he says, "not only may we find the mines worked by the Spaniards, but also discover the great river that is said to rise in the mountains where the Missouri has its source, and is believed to flow to the Western Sea." And he advises that a hundred and fifty men be sent up the river in wooden canoes, since bark canoes would be dangerous, by reason of the multitude of snags.[369]
In 1714 Juchereau de Saint-Denis was sent by La Mothe-Cadillac to explore western Louisiana, and pushed up Red River to a point sixty-eight leagues, as he reckons, above Natchitoches. In the next year, journeying across country towards the Spanish settlements, with a view to trade, he was seized near the Rio Grande and carried to the city of Mexico. The Spaniards, jealous of French designs, now sent priests and soldiers to occupy several points in Texas. Juchereau, however, was well treated, and permitted to marry a Spanish girl with whom he had fallen in love on the way; but when, in the autumn of 1716, he ventured another journey to the Mexican borders, still hoping to be allowed to trade, he and his goods were seized by order of the Mexican viceroy, and, lest worse should befall him, he fled empty-handed, under cover of night.[370]
In March, 1719, Bénard de la Harpe left the feeble little French post at Natchitoches with six soldiers and a sergeant.[371] His errand was to explore the country, open trade if possible with the Spaniards, and establish another post high up Red River. He and his party soon came upon that vast entanglement of driftwood, or rather of uprooted forests, afterwards known as the Red River raft, which choked the stream and forced them to make their way through the inundated jungle that bordered it. As they pushed or dragged their canoes through the swamp, they saw with disgust and alarm a good number of snakes, coiled about twigs and boughs on the right and left, or sometimes over their heads. These were probably the deadly water-moccason, which in warm weather is accustomed to crawl out of its favorite element and bask itself in the sun, precisely as described by La Harpe. Their nerves were further discomposed by the splashing and plunging of alligators lately wakened from their wintry torpor. Still, they pushed painfully on, till they reached navigable water again, and at the end of the month were, as they thought, a hundred and eight leagues above Natchitoches. In four days more they reached the Nassonites.
These savages belonged to a group of stationary tribes, only one of which, the Caddoes, survives to our day as a separate community. Their enemies, the Chickasaws, Osages, Arkansas, and even the distant Illinois, waged such deadly war against them that, according to La Harpe, the unfortunate Nassonites were in the way of extinction, their numbers having fallen, within ten years, from twenty-five hundred souls to four hundred.[372]
