G. W. Dunton has just finished burning a kiln of fine brick, which he will dispose of cheap for cash. Now if you want brick go and see Mr. Dunton, at John Boyn’s farm. (The Princeton Union, Mille Lacs County, Minnesota, Wednesday, August 21, 1878, Volume II, Number 35, Page 8)

Bricks. G. W. Dunton has made bricks since 1876 in the N. E. 1/4 of sec. 21, Princeton, nearly two miles north of the town and about a half mile west of Rum river. His product in 1879 was 400,000, selling at $7 per thousand. These are red bricks of good quality. Sand is mixed with the clay for tempering in the proportion of one to three. The section of the well at this brickyard, 24 feet deep, is horizontally laminated clay, yellowish to a depth of 16 feet, and dark bluish for the next 8 feet; water rose four feet from sand and gravel at the bottom.
