"Lawrence Moffat's Grist Mill located at West Stockbridge Village, just below "Shaker Mill Pond", was built in 1805 by . E. W. Thayer. This mill site is one of the oldest in the town, having been originally bought of the Indians by Elijah Williams, in 1763, the sale being in the form of a lease for 999 years, upon payment of one barley corn per year, if demanded. Here, Mr. Williams erected a forage selling it to E. W. Thayer, who erected the mill. From Mr. Thayer's hands the mill passed into the hands of the Tyringham Shakers, hence the name of "Shaker Mill". Mr. Moffat has owned the mill since 1867, having in partnership with him, Isaac M. Rees, until his death, in July, 1882."
