At Le Roy not many brick have been made. The Caswell House and the school house at that place are built of brick made at Le Roy. The quality of the LeRoy brick is as good as any seen at Austin. (The Geological and Natural History Survey of Minnesota, The Third Annual Report, For The Year 1874, N. H. Winchell, St. Paul Press Company, St. Paul, 1875, Page 186)
Red brick can be made at almost any place in the county. This has been demonstrated at Austin, Lansing, Le Roy and Frankford. At present there is no great demand for brick, and several establishments that were started have suspended operations. The Mower county court house, just finished, is one of the finest in the state. It is built of red pressed-brick from St. Louis, but red brick from Austin were used in the inner walls. (The Geological and Natural History Survey of Minnesota, Volume I, 1872-1882, N. H. Winchell and Warren Upham, Johnson, Smith & Harrison, Minneapolis, Minnesota, 1884, Page 366)
Abandoned brick yards were noted near Frankford, High Forest, and Leroy (Mower County), where common brick were made from the glacial drift and the loess. (Clays and Shales of Minnesota, Frank F. Grout and E. K. Soper, The University of Minnesota, Minneapolis, Minnesota, 1914, Page 135)
