Climatological data for the United States by sections (U. S. Dept. Agr., 

 Weather Bur. Climat. Data, 2 (1915), No. 13, pp. hOk, pls. 2, figs. 47).— This is 

 a summary of climatological data of each State for the year 1915. The data 

 are tabulated in detail and the principal weather conditions are summarized 

 for each month and for the year. 



Climatolog-ical data for the United States by sections (C7. S. Dept. Agr., 

 Weather Bur. Clbnat. Data, S (1916), Nos. 1, pp. 236, pis. 2, figs. 6; 2, pp. 236, 

 pis. 2, figs. 6). — These numbers contain brief summaries and detailed tabular 

 statements of climatological data for each State for January and February, 

 1916, respectively. 



Rainfall data of Berkeley, California, W. G. Reed ( Univ. Cal. Pubs., Engm., 

 1 (1915), No. 5, pp. 69-81). — Data for amount, frequency, and Intensity of rain- 

 fall at Berkeley, Cal., are summarized for the period from 1887 to 1915. 



Rainfall data of Berkeley, California, II, W. G. Reed and M. K. White 

 (Univ. Cal. Pubs., Engin., 1 (1916), No. 6, pp. 8S-116, pi. 1, fig. 1).— Supple- 

 menting the above report on rainfall observations, this paper summarizes 

 incomplete data obtained from a recording rain gage maintained by the depart- 

 ment of civil engineering of the university since 1911 for the purpose of study- 

 ing the water supply of the university. The data are discussed with special 

 reference to the frequency and intensity of the rainfall. 



It is shown that the maximum intensity for the place and period of obser- 

 vations was at the rate of 3.5 in. per hour for 5 minutes and 0.5 in. per hour 

 for 60 minutes. " A statistical and graphic study was made of all 12-hour pe- 

 riods for which intensity records are available. From this study the following 

 indications have appeared: (1) When 0.8 in. falls in 12 hours there is a chance 

 that the maximum rate for 1 hour exceeds 0.5 in.; (2) when 0.8 in. falls in 

 12 hours it is probable that 0.3 in. in 1 hour has been exceeded; this rate is 

 half the maximum shown by the Grunsky curve and has been assumed as the 

 lower limit of intensity of practical importance; (3) when 0.8 in. falls in 12 

 hours there is a chance that 0.15 in. in 5 minutes has been exceeded ; this is the 

 maximum given by the Grunsky curve for 5 minutes; (4) when 0.8 in. falls 

 in 12 hours it is probable that 0.07 in. in 5 minutes has been exceeded ; this 

 has been assumed as the lower limit of intensity of practical importance; it 

 is half the maximum given by the Grunsky curve." 



California earthquakes during 1915, A. H. Palmeb (Bui. Seismol. Sac. 

 Amer., 6 (1916), No. 1, pp. 8-25, figs. 4).— A complete record is given. 



Meteorological observations in Panama (Bol. Estad. Panama, No. 26 (1915), 

 pp. 2-7).— Observations on pressure, temperature, humidity, precipitation, 

 cloudiness, and winds during 1913 are summarized in tables. 



Annual report of the weather bureau, 1914 (C7. S. Dept. Int., Ann. Rpt. 

 Weather Bur. [Philippine Islands], 1914, pts. 1 and 2, pp. i^O). —Part 1 of this 

 report contains brief statements regarding the stations, personnel, and work of 

 the Philippine Weather Bureau. Part 2 gives tabular summaries of observa- 

 tions at the Central Observatory of Manila during 1914 on pressure, tempera- 

 ture, relative humidity, vapor pressure, clouds, and direction, velocity, and 

 frequency of winds. 



Is rainfall decreasing? (Agr. Gaz. N. 8. Wales, 27 (1916), No. 4 p 246) — 

 The average rainfall of twelve towns in New South Wales by 10-year periods 

 from 185&-1915 Is tabulated and compared with the average for the whole 

 period. The data are considered too limited to permit of definite conclusions,
