One of the large lumber projects of E. A. Irvin, son of William, was the "Big Mill" erected in 1889 on site of present tannery. Col. E. A. Irvin ("Col. Irvin", as he was familiarly known) and James Cassidy, owned timberlands "up the river." Logs were floated down to the Curwensville mill, operated by Hoover, Hughes & Co. of Centre County, and bore this name because it was the largest mill of its kind in the state. (George Hoover, of this firm, an uncle of Mrs. Frank C. Mullen.)1008
