SCN 1984

     In the middle of the 19th century Charles Bontemps, a French engineer, experimented with pneumatic technology for the transmission of the mail. The earliest pneumatic postal networks were in London, Paris, and Berlin in the late 1860's. The system in Paris was begun in 1865-1867. The Seven Weeks War (1866) and the Franco-Prussian War (1870) prevented full scale development.
     Non-continuous air flow through one-way tubes was used to propel "trains" of carriers at 15 minute intervals. The system continued to expand in the period from 1871 to 1918. In 1907 over nine million items were transmitted. By 1982 the number fell to less than 650,000 and the system was closed in 1984.
     The stamp may reflect the actual system at some point in its history, or a part of that system, or it might simply be an impression of the principles..
