Climatology of Oklahoma (Bicn. h'lil. Okla. Bd. Agr., 1 (1907-8), pt. 8, 

 pp. 8). — Observations on temperature, dates of Ivilling frosts, precipitation, 

 cloudiness, and prevailing winds from IStO.S to 190S are summarized by the 

 director of the State weather service. 



Report of meteorologist, N. Helme (Rhode Island Sta. Rpt. 1908, pp. 325- 

 S-'fl). — Observations at Kingston on temperature, precipitation, prevailing 

 winds, and general character of the weather are given for each month of the 

 year ended June 30, 1908. The mean temperature for that period was 48.5°, 

 the precijiitation 53.75 In., and the number of clear days 158. 



Meteorology (Imp. Dcpt. Agr. We.st Indici, Rpt Agr. and Bot. Dcpts. Bar- 

 hadoH. 1898-1 907 . pp. 31-37. dgnis. 2). — This report gives observations on pres- 

 sure, temperature, rainfall, and wind made at the botanic station, Barbados, as 

 well as rainfall returns for the island for the year 190(5, with tables showing 

 averages of the general meteorological observations for the past 10 years and 

 the average rainfall of the island for GO years (1847-1906) as related to the 

 crop of sugar exported each year during the same period. 



An attempt is made to show the relation between rainfall and sugar produc- 

 tion by means of diagrams. The rainfall curves show distinct evidence of 

 ].eriodicity in jirecipitation and that there were wet years around 1853, 18(34-65, 

 1879, and 1895, while the dry periods centered around 1858, 1871, 1883-84, and 

 the ])resent time. The sugar croj) curves show no direct relationship between 

 la infill I and sugar production. The curve of production runs from its lowest 

 point in 1X47 to its highest point about 1889, and since that year has decidedly 

 decreased.
