				Bancroft Ranch House
				
				Adobe built about 1850 by A.S. Ensworth. Home of Capt. Rufus K. Porter and family. Curved timbers brought from the "Clarissa Andrews", famed coaling hulk formerly of the Pacific Mail Steamship Co. Historian Hubert Howe Bancroft later owned this estate and here wrote a part of his monumental history of California.
