Mexico; or by the Missouri to the passes of the Rocky Mountains, where rise the headwaters of the Columbia, which brings the voyageur to the Pacific. But if the explorer follows Lake Superior to the present boundary line between Minnesota and Canada, and takes the chain of lakes and rivers extending from Pigeon river to Rainy lake and Lake of the Woods, he will be led to the Winnipeg river and to the lake of the same name. From this, by streams and portages, he may reach Hudson bay; or he may go by way of Elk river and Lake Athabasca to Slave river and Slave lake, which will take him to Mackenzie river and to the Arctic sea. But Lake Winnipeg also receives the waters of the Saskatchewan river, from which one may pass to the highlands near the Pacific where rise the northern branches of the Columbia. And from the lakes of Canada there are still other routes to the Oregon country.[61] At a later day these two routes to the Columbia became an important factor in bringing British and Americans into conflict over that territory.

In these water-systems Wisconsin was the link that joined the Great Lakes and the Mississippi; and along her northern shore the first explorers passed to the Pigeon river, or, as it was called later, the Grand Portage route, along the boundary line between Minnesota and Canada into the heart of Canada.

It was possible to reach the Mississippi from the Great Lakes by the following principal routes:[62]

1. By the Miami (Maumee) river from the west end of Lake Erie to the Wabash, thence to the Ohio and the Mississippi.

2. By the St. Joseph's river to the Wabash, thence to the Ohio.

3. By the St. Joseph's river to the Kankakee, and thence to the Illinois and the Mississippi.

4. By the Chicago river to the Illinois.

5. By Green bay, Fox river, and the Wisconsin river.

6. By the Bois Brulé river to the St. Croix river.

Of these routes, the first two were not at first available, owing to the hostility of the Iroquois.

Of all the colonies that fell to the English, as we have seen, New York alone had a water-system that favored communication with the interior, tapping the St. Lawrence and opening a way to Lake Ontario. Prevented by the Iroquois friends of the Dutch and English from reaching the Northwest by way of the lower lakes, the French ascended the Ottawa, reached Lake Nipissing, and passed by way of Georgian Bay to the islands of Lake Huron. As late as the nineteenth century this was the common route of the fur trade, for it was more certain for the birch canoes than the tempestuous route of the lakes. At the Huron islands two ways opened before their canoes. The straits of Michillimackinac[63] permitted them to enter Lake Michigan, and from this led the two routes to the Mississippi: one by way of Green bay and the Fox and Wisconsin, and the other by way of the lake to the Chicago river. But if the trader chose to go from the Huron islands through Sault Ste. Marie into Lake Superior, the necessities of his frail craft required him to hug the shore, and the rumors of copper mines induced the first traders to take the south shore, and here the lakes of northern Wisconsin and Minnesota afford connecting links between the streams that seek Lake Superior and those that seek the Mississippi,[64] a fact which made northern Wisconsin more important in this epoch than the southern portion of the state.

We are now able to see how the river-courses of the Northwest permitted a complete exploration of the country, and that in these courses Wisconsin held a commanding situation,[65] But these rivers not only permitted exploration; they also furnished a motive to exploration by the fact that their valleys teemed with fur-bearing animals. This is the main fact in connection with Northwestern exploration. The hope of a route to China was always influential, as was also the search for mines, but the practical inducements were the profitable trade with the Indians for beaver and buffaloes and the wild life that accompanied it. So powerful was the combined influence of these far-stretching rivers, and the "hardy, adventurous, lawless, fascinating fur trade," that the scanty population of Canada was irresistibly drawn from agricultural settlements into the interminable recesses of the continent; and herein is a leading explanation of the lack of permanent French influence in America.

WISCONSIN INDIANS.[66]

"All that relates to the Indian tribes of Wisconsin," says Dr. Shea, "their antiquities, their ethnology, their history, is deeply interesting from the fact that it is the area of the first meeting of the Algic and Dakota tribes. Here clans of both these wide-spread families met and mingled at a very early period; here they first met in battle and mutually checked each other's advance." The Winnebagoes attracted the attention of the French even before they were visited. They were located about Green bay. Their later location at the entrance of Lake Winnebago was unoccupied, at least in the time of Allouez, because of the hostility of the Sioux. Early authorities represented them as numbering about one hundred warriors.[67] The Pottawattomies we find in 1641 at Sault Ste. Marie,[68] whither they had just fled from their enemies. Their proper home was probably about the southeastern shore and islands of Green bay, where as early as 1670 they were again located. Of their numbers in Wisconsin at this time we can say but little. Allouez, at Chequamegon bay, was visited by 300 of their warriors, and he mentions some of their Green bay villages, one of which had 300 souls.[69] The Menomonees were found chiefly on the river that bears their name, and the western tributaries of Green bay seem to have been their territory. On the estimates of early authorities we may say that they had about 100 warriors.[70] The Sauks and Foxes were closely allied tribes. The Sauks were found by Allouez
