Red bricks were also made during several years from the till on the south side of Rush creek at Rush City, by Archibald Peers. Only about a third part of these could be used, the remainder being crumbled by lime particles. (A Report on the Geological and Natural History Survey of Minnesota, Volume II, 1882-1885, N. H. Winchell and Warren Upham, Pioneer Press Company, St. Paul, Minnesota, 1888, Page 424)
At Rush City a plant operating for several years made red brick from till. (Clays and Shales of Minnesota, Frank F. Grout and E. K. Soper, The University of Minnesota, Minneapolis, Minnesota, 1914, Page 87)
