upper part is set in the ground, leaning against a huge bowlder, and 
is held in that position by wire, well tightened. The highest point of 
the bowlder is marked with a black cross, and is G.815 feet above the 
11-foot mark. Measurement was made from gaging box suspended 
from cable placed across just above the gage. The channel is sandy 
and shifting. 
SAN MARCIAL STATION, ON THE RIO GRANDE. 
This station is located about one-half mile south of San Marcial, 
IS. Mex., at the bridge of the Atchison, Topeka and Santa Fe Kailroad. 
It was established by Mr. Arthur P. Davis on January 29, 1895. The 
observer is Mr. Bert Halseth, San Marcial, ¥. Mex., whose house is 
about one-half mile distant. The gage is of hard pine timber, 9 by 5 
inches by 25 feet, anchored and bolted to the east end of the second 
pier from the south. It is inclined and painted white. The distance 
between the footmarks is 1.6 feet. The 13-foot mark is level with the 
extension of the pier, to which the gage is anchored. The 15-foot 
mark is level with the top of the capstone on which the bridge truss 
rests. The shifting channel is of sand and mud. Measurements were 
made from the same bridge. On August 8, 1889, a station was estab- 
lished near San Marcial, and a measurement was made which gave 
a discharge of 19 second-feet. Soon after this date, however, the river 
gage was destroyed and the locality was abandoned until 1895. 
EL PASO STATION, ON THE RIO GRANDE. 
This station is located at the pump house of the smelting works near 
the station "Town," on the Atchison, Topeka and Santa Fe Railroad, 
1£ miles above Old Fort Bliss. It was established on January 24, 
1895, by Mr. Arthur P. Davis. The observer is Mr. 0. T. Pelham, of El 
Paso, Tex. The distance from the gage to the pump house is about 50 
feet. The gage is of 4 by 6 inch timber, inclined, bolted to solid rock; 
is 24 feet long, and is continued upward on a 2 by 4 inch by 12-foot 
piece. The distance between the footmarks is 2.9 feet. The bench mark 
is an iron core in the center of the masonry monument that marks 
the corner of the smelter company's land, on a rock knoll just above 
the gage. It is 8.04 feet above the 11-foot mark on the gage. Measure- 
ment was made from a cable just below the gage. 
The first river station on the Rio Grande near El Paso was at Old 
Fort Bliss, about 1,500 feet above the Mexican dam. Observations and 
measurements were made here from May 10, 1889, until the end of June, 
1893, except at times when the river was dry. Later, during a sudden 
flood, the gage was deeply buried in mud, and on the abandonment of 
Old Fort Bliss the river rods and equipment were stolen, necessitating
