exposed surface. This last has also retarded the former devastations by 

 prairie fires. This wooded portion is on the eastern edge of the "big 

 woods" of Minnesota, or bois fort, well and long known as one of the great 

 physical features of the surface of the state. The underlying causes for 

 this difference of surface and drainage features will appear in the descrip- 

 tion of the drift and geological structure. 



Water-powers. Several valuable water-powers have been improved in Bice county. These 

 are chiefly in the valley of the Cannon river, viz: 



Northfield mills. Jesse Ames' sons, Northfleld; in the oldmill the present capacity is 80 bar- 

 rels per day; 3 run of stone (two for feed) , nine feet head; one 45-inch and one 35-inch Leffel wheel, 

 two 27-inch Huston wheels and one 34-inch Huston wheel (one is fora machine shop); the 35-inch 

 Leffel wheel has 20.7 horse-power, and the 34-inch Huston has 21 horse-power. The new mill has 

 a capacity of 400 barrels; 9 feet head; two 54-inch Victor wheels, each having a rated capacity of 

 80 horse-power; one 35-inch Leffel wheel with 21 horse-power; twenty double rollers; three single 

 rollers; Gray patent of Allis' roll; three flour buhrs. 



Dundas mills. E. T. Archibald & Co.; Dundas, on the Cannon river; partly run by steam; 

 full capacity 600 barrels per day; 10 feet head; two 48-inch Leffel wheels; four buhrs; 37 single 

 rollers of Gray's Allis' patent. This mill is about half built of Trenton limestone, and the old 

 Archibald mill, on an island in the river, now dismantled, is wholly of this stone. Another mill 

 at Dundas is run wholly by steam. 



Cannon Valley roller mill. S. E. i sec. 8, Cannon City, on the east side of the Cannon river; 

 owned by R. II. Scott and sons; seven feet head, four Leffel wheels, all 48-inch, and one La Croix

 Allis rollers; one of Stevens single, smooth rollers; three buhrs (one for feed, run by the La Croix 

 wheel); full capacity 130 barrels in twenty-four hours. 



There is a fine water-power at Faribault in the Cannon river, between the railroads, owned 

 by Mr. Mattison, where the mill was lately burned. The fall here is about six feet and will fur- 

 nish several hundred horse-power. 



Tlie Polar Star mills, Faribault, owned by F. A. and S. L. Bean, on the south side of the 

 Cannon river; run partly by steam; head eight to eleven feet, according to the season; one Amer- 

 ican, or Dayton, 75-inch turbine wheel, two Leffel wheels, one flfty-six and the other forty-eight 

 inches; at eleven feet head these Leffel wheels produce, one, ninety and the other fifty-three horse 

 power, and the American wheel one hundred and forty horse-power; in summer, however, steam 

 is necessary to run the mill; rollers are made by Allis (Gray's), Cosgrove, Noye, and Dalton; three 

 double smooth rollers, and five single smooth, seven sets of corrugated single rollers; full capacity 

 375 barrels in twenty-four hours. 



The water-power mill at Morristown is owned by C. H. Hershey; head of water seven feet; 

 Case turbine wheel, fifty-four inches, twenty-seven horse-power. Two buhrs (one for feed); full 

 capacity thirty-eight barrels in twenty-four hours. 



The mill at the outlet of Eoberd's lake, N. W. J sec. 22, Wells, owned by T. G. Scott, is 

 known as the Roberd's Lake mill. In high water it has a head of sixteen feet, but in ordinary 

 stage of water only twelve feet; one Small's turbine wheel of forty-eight inches and sixty horse- 

 power (under twelve feet head); one double set of Allis' make of Wegmann's patent rollers; three 

 buhrs (one for feed); capacity for wheat fifty barrels each twenty-four hours. 

 The following mills are on the Straight river :
