Glass formats, 1905-1906 and undated

This subseries consists of 50 glass images in two formats. Most are 5x7-inch glass plate negatives of people, a factory, and machinery. Nothing is identified, but the inscribed dates of 1905 and 1906 indicate the images probably depict the construction of the sugar beet factory at Holly (or Lamar), along with people associated with the facility or company. The lantern slides show various wooden structures in a streambed. Materials are retained in the order found, with glass plate negatives listed first and lantern slides next.
