author
1905–1979
A quiet New England writer, he is remembered for a compact but vivid account of local history in action. His best-known book follows the restoration of Baxter's Mill on Cape Cod and captures the pleasure of saving an old landmark by hand.

by A. Harold Castonguay
Born in Enfield, Connecticut, in 1905 and later associated with West Yarmouth, Massachusetts, A. Harold Castonguay is credited with Two men on a mill: The story of the restoration of Baxter's Mill, originally published in 1962. The book centers on the revival of the old water-powered Baxter mill on Cape Cod and reflects a strong interest in local history, practical work, and preservation.
Only a small amount of biographical information is easy to confirm, but the surviving record suggests a writer closely connected to New England places and stories rather than a large public literary career. Today, his name remains linked above all to Baxter's Mill and to a warm, straightforward piece of regional nonfiction that preserves a slice of Cape Cod history.
He died in 1979.
