These bricks in the outer part of the kiln are red, and gradually change to cream-colored in the central part of the kiln, where they were subjected to greater heat, while next to the fires they are greenish yellow.

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.
