As the largest population center in Vermont, it’s to be expected that Burlington would have more than one post office to serve its population. According to Vermont Postal History: The Branches, Stations & CPO of the Green Mountain State (Abajian, Granger, 2000), Burlington has had 32 subsidiary offices since the late 1890s.
In their 2000 listing, Abajian and Granger noted that six of the offices had no known postal cancels: Station No. 1 (Elmwood Ave.)(1897-1939), Station No. 2 (1899-1920s), Station No. 2 (Andersons) (1951-1960), Station No. 3 (1916-1927), Station No. 4 (1901-1927), and Station No. 5 (1902-1918).
We can now show a postal marking from Station No. 4, which was located at 1 Church Street.
Stations such as this probably had no postmarking devices but rather generic Burlington postmarks. However, they did need red concentric cancels for use on official documents, registered mail and other such uses.
