The Blacksher family owned part or all of several Alabama logging companies. Blacksher-Miller, based in Brewton, is represented by a skinny-gauge Mogul in Locobase 12119. As noted in that entry, David Blacksher left that company to join his family operations at Magazine, Ala (Locobase 12584).
The oldest of the Blacksher enterprises was the one at Uriah in Monroe County owned by James Uriah Blacksher. The Blacksher Home account says that at one point, Blacksher owned more than one hundred thousand acres of land and a large lumber industry. He also owned a bank, a store, and railroads." Uriah was named for the man who had "a big impact on the the settling of southwest Alabama and the development of Monroe County."
Agnes was a typical small wood-burning logging Consolidation. Her specification included a "long and low" tender "so Engineer can see while backing" and a Radley & Hunter spark-arresting stack.
