The direction and velocity of the wind at Fort Conger was observed and recorded hourly. The direction was noted only to eiglit points of the comi)ass, and is in all cases true. The velocity is given in miles per hour, having been recorded in rriiles actually blown in each hour, as shown by a Robinson anemometer and registered by an electro-circuit, as is customary at Signal Service stations. 'I'he velocity of the wind was measured by a Robinson anemometer, which was situated 31 feet [;'] above the ground, and 50 feet [15'"] above the sea, where it was exposed to the full force of all winds. The large wind vane, 50 feet [15'") above the ground, and 71 feet [z2"'J above the sea, although carefully mounted, was occasionally so interfered with by frosf work, that the vane did not swing with very light winds, consecjuently the electrical record of directions was not always reliable, and was never used. The observer noted the direction, not only of the large vane, but also of a light vane, wliich, 10 feet [3'"] above the ground and 60 feet fig'"] above the sea, was situated near the instrumen*: shelter, and at some distance from the house. The two vanes generally accorded, but in difference the direction was determined by the light vane. The country, as will be observed from the accompanyinfi; map, is particularly open from S. to WSW., and moderately so due E. of the station. In other directions the land rises to an elevation of 1,500 t'' 1,800 feet [450 to 550'"] within i or 2 miles of the station. The configuration of the fiords, valleys, and straits adjacent to Fort Conger is frequently such that the wind blows, as a rule, only from two
