An exhibit of photographs taken by UC Cooperative Extension's first farm advisor in Marin County will be on display at the Marin County Fair June 30 ­– July 4.

M.B. Boissevain, who became a UCCE advisor in 1920, took approximately 500 photos of Marin agriculture and its people during his 30-year career. Ellie Rilla, UCCE advisor in Marin County, and David Lewis, UCCE director and advisor in Marin County, have written a book about the agricultural history of the county based on Boissevain’s photos and farm reports.

The 126-page book “Marin Agrarian Roots” contains 82 images photographed by Boissevain.

The book will be available for purchase at the fair for $25. It also will be available at Book Passage, Toby’s Feed Barn, Point Reyes Books, Tomales Regional History Center and Jack Mason Museum of West Marin History.
