Inscription. "In October 1877, Bench Mark "A" was cut on the water table of the recently rebuilt courthouse in Hagerstown, Maryland", reads the report of the coast and geodetic survey to President McKinley. This was the beginning point of a transcontinental level line which by way of Williamsport and then along the C&O Canal reached Hancock in one month but it was not until 1904 that the line extended from the Atlantic to Pacific Oceans.

Bench Mark "A" is not just of historical interest, but has been included in leveling surveys conducted in 1931, 1941, and 1979. It has remained very stable in relation to other nearby marks. This mark was chosen to be part of a releveling project completed in 1988.
