91°. . . . The amount of rainfall is large, and it seems to be somewhat larger at 

 Hamilton and Ireland Island than at St. George's. According to Lefroy's tables, 

 covering 11 and 16 years, respectively, it was 54.66 in. at Ireland Island and 48.61 in. 

 at St. George's. The amount near Hamilton in later years usually varied between 58 

 and 63 in., 'but in 1898 was only 48.19, and in* 1900 it was 67.05 in. The rainfall is 

 usually pretty well distributed throughout the year, but is generally greatest in Octo- 

 ber and November and least in the summer months, when droughts are not uncom- 

 mon, but seldom very prolonged. Usually more or less rain falls (m from 190 to 

 207 days; and on at least half of the days of all the months from November to April. 

 But in many cases the rains ai'e mere showers of very brief duration, . . . and in 

 the summer time [the air] is often nearly saturated with moisture, so that it is very 

 oppressive to many persons." 



Fogs and hailstorms are rare. Thunderstorms are very common and sometimes 

 violent. High winds are frequent, and destructive hurricanes sometimes occur. 

 Frost, ice, and snow have been observed only a few times in the history of the islands, 

 and no great damage has ever been done by them. 



Meteorological observations for 1902 {Colorado Sia. lijjt. 190:i, pp. 153-199. 

 206-213). — Tallies prepared 1)y R. E. Trimble give daily and monthly summaries of 

 observations during 1902 on temperature, pressure, ijrecipitation, dew point, relative 

 humidity, terrestrial and solar radiation, direction and movement of wind, and 

 occurrence of frost at Fort Collins, Colo. ; monthly summaries of similar obser- 

 vations at Rockyford and Cheyenne Wells; and monthly summaries of observations 

 on temperature and precipitation at Long's Peak House near Estes Park (elevation 

 about 9,000 ft.), Gleneyre (elevation about 8,000 ft.), and Cowdrey (formerly Pink- 

 hampton), North Park (elevation 8,400 ft.). 



Tables are also given which summarize the monthly and annual precii^itation at 7 

 different places in the State and show the monthly and annual rainfall at Fort Col- 

 lins for the period from 1872 to 1902 with the normals for tliat period. The follow- 

 ing is a summary of the principal meteoi'ological data reported for Fort Collins: 

 Mean temi^erature (i maximum and 5 minimum), 47.4° F. ; maximum, 99.6°, 

 August 1; minimum, — .'}1.4°, January 6; precipitation, 18.43 in. ; snowfall, 24.6 in.; 

 mean relative humidity, 67 per cent. The normals for this place are, temperature, 

 46.6° F. ; precipitation, 14.66 in.; mean relative humidity, 65.3 per cent.

 and bright sunshine during 1901 (Jour. Roy. Agr. Soc. England, 63 {1902), j/ji. 

 457-469). — 01)servations on temi:)erature, rainfall, sunshine, etc., in Great Britain 

 during 1901 and preceding years are reported and the general weather conditions 01

The cereal and other crops of Scotland for 1902, and meteorology of the 

 year relative thereto, A. Buchan {Trav^. Iligldaiul and Agr. Soc Scotland, 5. ser., 

 15 {1903), pp. 319-350). — A summary is given of observations on pressure, tempera- 

 ture, rainfall, cloudiness, direction of wind, etc., during the year, with notes on the 

 general weather conditions during each month and crop and live stock reports from 

 a number of different localities in Scotland. 



Variations in rainfall at Hawkesbury Agricultural College, C. T. Musson 

 {Agr. Gaz. New South Wales, I4 {1903), No. 4, pp. 345-348, pis. 2).— The results of 

 observations with a series of 50 rain gages are reported, which show considerable 

 variations in rainfall over a very small area. " Even in the case of heavy falls the 

 two edges of an acre of ground, of a scfuare form, might receive rain varying by 20 

 per cent or more. An accumulation of such variations would mean an important 

 factor in the fortunes of the plant inhabitants, which would l)e em^jhasized in cases 

 of where plant water requirements were low with heavy rain or high with least rain, 

 or where soils varied much in texture and in relation to water-carrying capacity."
