SPRINGFIELD STATION, ON SOUTH BRANCH OF POTOMAC. 
Measurements of the South Branch of the Potomac are made at a 
point about 2 miles above Springfield, W. Va. Observations were 
begun on June 3, 1894, and continued until October 20, and were 
resumed in the succeeding year. Heights of water were measured by 
a wire gage, which is read by being drawn up along a scale divided into 
feet and tenths, attached to the guard rail of the bridge on the lower 
side. The channel is rocky and gravelly and is well adapted to dis- 
charge measurements, which are made from the bridge.

CUMBERLAND STATION, ON POTOMAC RIVER. 
Observations of river height are taken at the West Virginia Central 
Eailroad bridge, Cumberland, Md., about 200 yards below the dam on 
the Potomac. They were begun on June 11, 1894, and continued 
throughout that year. The gage is a vertical rod 10 feet long, bolted 
to the east end of the abutment of head gates above the dam. The 
channel consists of loose rocks and is not liable to change. The dis- 
charge measurements are made from the bridge.
