The H. C. Knowles Lumber Company began as the Henderson-Knowles Lumber Company in 1935, according to Fred McKenzie. The operation was referred to as the “Knothole.” Located in a pasture once owned by an individual named Johnson, behind the old Baptist Church, the company ran as a partnership until the beginning of World War II. E. C. Henderson sold out and moved to Marshall. Knowles continued the sawmill until 1947, when he sold his planer to M. L. “Bud” Felker, Jr. Henderson dismantled the remaining portion of the sawmill and moved it to Pyland community.
