 daily range, 22.1. Humidity. — ]\Iean dewpoint, 40.2; mean relative humidity, 73.5. 

 Precipitation. — Greatest annual, 1897, 57.05 in.; least annual, 1894, 32.64 in.; mean 

 annual, 46 in. Wind. — Mean annual movement, 51,566 miles; maximum pressure 

 per square foot, 43 lbs., September 11, 1895. Weather. — Mean cloudiness observed, 

 52.4 per cent; total cloudiness recorded by the sun thermometer, 22,400 hours, or 50.3 

 per cent ; number of cloudy days, 1,444. Bright sunshine. — Number of hours recorded,

 vations during 1898 and 1899 on temperature, humidity, precipitation, snowfall, dew- 

 ])oint, days of frost or dew, cloudy and stormy days, and direction of the wind at 

 Fort Collins, Rockyford, and Cheyenne Wells, and on temperature, precipitation, 

 snowfall, and stormy days at Estes Park (at base of Longs Peak, elevation 9,000 ft. ), 

 Pinkhampton (elevation 8,400 ft. ), and Gleneyre (elevation 8,000 ft. ). The monthly 

 and annual rainfall at Fort Collins (1872-1899) and at 7 additional places in the 

 watershed of the Cache la Poudre River is also reported. Observations during 13 

 years (1887-1899) on the evaporation from a water surface are tabulated. 



Meteorological svtmmary, J. S. ^Ioore {Mississlp]ti Sta. Rpt. 1899, pp. 4^-47). — 

 Tables are given which show the daily and monthly precipitatioji with departures 

 from normal, monthly temperatures with departures from normal, cloudiness, and 

 direction of the wind for the year ended June 30, 1899. The most remarkal)]e fea- 

 ture of the weather during this ]>eriod was the extreme low temperatures of February 

 11-14, 1899, during which the temperature fell to —8° F., and the continued cold 

 and wet weather of ]\larch and April. 



Summary of temperature, rainfall, and sunshine, E. F. Ladd {North Dakota 

 Sta. lipjt. 1899, p. 14). — Tables give the maxima, minima, and mean temperatures for 

 each month of 1899; al'^o the total rainfall, monthly and yearly, for 1899 and 7 pre- 

 ceding years, and the hours of sunshine. The rainfall during 1899 was 21.21 in.; the 

 mean annual rainfall for 8 years (1892-1899) Avas 19.87 in.
