Industry in Great Valley, 1875 (another use for the trees cut in the area, not every tree was floated down the Allegany River). The reference in the title to "the last block factory" we believe, relates to the shoe block factories. This was submitted by Great Valley historian, Marilyn Eddy Siperek. Clarification would have to be sought through her. For more information about the shoe block factories check what Town of Ellicttville. Historian, Mary Elizabeth Dunbar has written about those businesses in Ellicottville.
