Page 188. Bricks. W. H. Wyman has made bricks since 1878 in the southwest quarter of section 20, Hutchinson (north township), about two miles north of
Page 189. the village. In 1879 his product was 100,000, sold at $7.50 to $8 per thousand. These bricks have a light red color. The soil to a depth of six inches is removed, and the stratum occupying the next one and a half feet below, which is a hard, light gray clay, is used for the brick-making, requiring no admixture of sand. This clay continues at least six feet deeper, but in that portion it becomes soft and yellowish, and bricks made from it are cracked by particles of lime. Its first one to two feet below the layer used for the manufacture of bricks is streaked with iron-rust. The locality is a marsh, having only about two acres of the brick-clay.
