The southern boundary strikes the river twenty-two miles below La Crosse. If I were to go down there and turn my steps due west, I might walk two hundred and sixty-four miles along the Iowa line before reaching the southwestern corner of the State. The western side is the longest, and if I were to start from the southwestern corner and travel due north, I should have a journey of three hundred and sixty miles to accomplish before reaching the northern boundary,--the line between the United States and British America. Starting from Pembina, at the northwest corner of the State, on the Red River of the North, and travelling due east eighty miles, I should reach the Lake of the Woods; sailing across it sixty miles, then entering the river leading to Rainy Lake, I might pass through the wonderful water-way of lakes and rivers reaching to Lake Superior,--a distance of about four hundred miles. The eastern boundary formed by the Mississippi, St. Croix, and Lake Superior is more irregular. Its general outline, as we look at it upon the map, is that of a crescent, cutting into Minnesota, the horns turned eastward. The area within the boundaries thus described is estimated at 84,000 square miles, or 54,760,000 acres. It is a territory larger than Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, and Connecticut combined. Here, upon the Mississippi, I gaze upon bluffs of gray limestone wrought into fantastic shape by the winds and storms of centuries and by the slow wearing of the river; but were I to climb them, and gain the general level of the country, I should behold rolling prairies dotted with lakes and ponds of pure water, and groves of oak and hickory. All of Minnesota east of the Mississippi is a timbered region. Here and there are openings; but, speaking in general terms, the entire country east of the river is a forest, which through the coming years will resound with the axe of the lumberman. When we go up the Mississippi eighty miles above St. Paul to St. Cloud, we shall find the Sauk River coming in from the west; and there the Mississippi is no longer the boundary of the timbered lands, but the forest reaches across the stream westward to Otter-Tail River, a distance of more than one hundred miles. The Sauk River is its southern boundary. All the region north of the Sauk, at the head-waters of the Mississippi and north of Lake Superior, is well supplied with timber. A belt of woods forty miles wide, starting from the Crow-Wing River, extends south nearly to the Iowa boundary. It is broken here and there by prairie openings and fertile meadows. The tract is known throughout the Northwest as the region of the "Big Woods." There are fringes of timber along the streams, so that the settler, wherever he may wish to make a home, will generally find material for building purposes within easy reach. In this respect Minnesota is one of the most favored States of the Union.
