Two brick yards (Le Sueur) each make about one-half million brick annually, operated by Henry Kruse and H. Dehling. (History of the Minnesota Valley, Including the Explorers and Pioneers of Minnesota, Rev. Edward D. Neill, North Star Publishing Company, Minneapolis, 1882, Page 484)
At Le Sueur, the alluvium of the Minnesota River is favorably exposed along the Omaha Railroad. Soft-mud brick can be produced at the rate of about 10,000 per day. The brick are red in color, and have stood the test of service since 1882 in some of the buildings in Le Sueur. (Clays and Shales of Minnesota, Frank F. Grout and E. K. Soper, The University of Minnesota, Minneapolis, Minnesota, 1914, Page 125)
