After passing about a league beyond the Montreal, the voyager reaches a curve in the lake shore, at which it bends to the north and northwest. This curve is observed to extend to the De Tour of the great bay of Fond du Lac, a computed distance of the _voyageurs_ of thirty-six miles, which, as before indicated, is about one-third overrated. The immediate shore is a level plain of sand, which continues to Point Chegoimegon, say eighteen miles. About two-thirds of this distance, the Muskeego[58] River enters through the sandy plain from the west. This is a large stream, consisting of two primary forks, one of which connects it with Chippewa River, and the other with the River St. Croix of the Mississippi. The difficulties attending its ascent, from rapids and portages, have led the French to call it Mauvaise, or Bad River.[59] [58] From _Muskeeg_, a swamp or bog, and o, the sign of the genitive. [59] MUSKEEGO, or MAUVAIS RIVER.--In 1831, the United States government placed under my charge an expedition into the Indian country which ascended this river, with a view to penetrate through the intervening region to the Mississippi. Indian canoes were employed, as being best adapted to its rapids and portages, which were managed by _voyageurs_. A detachment of infantry, under Lieut. R. Clary, was added. The tribes in this secluded region were then meditating the outbreak which eventuated the next year in the Black Hawk War. This expedition ascended the river through a most embarrassing series of rapids and rafts, which often choked up its channel for miles, into a long lake, on its summit, called Kagenogumaug. From the northwest end of this, it passed, from lake to lake, to the Namakagun fork of the River St. Croix of the Mississippi, descended that stream to Yellow River, then retraced the Namakagun to a portage to Ottowa Lake, a source of Chippewa River, then to a portage into Lac Chetac, the source of the Red Cedar, or Follavoine River, and pursued the latter to the main channel of the Chippewa, and by the latter into the Mississippi, which it enters at the foot of Lake Pepin; thence down the Mississippi to Prairie du Chien, and through the present area of the State of Wisconsin, by the Wisconsin and Fox Rivers, to Green Bay; thence through Lakes Michigan and Huron to Sault de Ste Marie.
