The original plat of Mason, by Charles Noble, was acknowledged Feb. 6, 1838, and recorded June 23, 1838. The only clew given by the plat to its location is the statement thereon that "Mason is situated on sections Nos. 8 and 9 of town 2 north, or range No. 1 west." The original town was laid out in thirty-one blocks, the western boundary being near the east side of Sycamore Creek.

The "Consolidated Plat of the Village of Mason," including the old plat, Pease & Smith's, McRobert & Sackrider's, Holt & Steel's, Barnes', Condon's, and Price's additions, was conveyed by Louis D. Preston, and acknowledged Dec. 26, 1866. Smith & Pease's addition had been laid out April 20, 1865; Congdon's addition, by R. D. and Richard Congdon, June 4, 1866; Steele & Holt's addition, Sept. 21, 1866.

Additions have since been made as follows: Griffin's addition, by R. F. Griffin and others, acknowledged Dec. 7, 1869; Pratt's addition, by Alex. Bush and others, Nov. 10, 1873; Darling & Barnett's addition, by Nathan Darling and William S. Barnett, May 2, 1873.
