The astronomical station is situated near Austin, Nev., in the canon through which the road to Belmont piisses. A short distance above the Manhattan Mill, to the east of the station, the land rises rapidly to Mount Prometheus; to the north, there is a slope downward to the valley of the Eeese River. The mountains to the south and west rise to a height of several hundred feet above the station. The weather seems to have been quite fair when the station was occupied; at least, at night. During the day the clouds accumulated about 3 p. in., clearing again at 11 p. m. No detailed meteorological observations were made by the observer. The observations were taken in the same tent used at Carlin and Battle Mountain; the instrument was placed on three pieces of board buried three feet in the ground. The observer, E. P. Austin, was assisted by two soldiers. |
