Grordon ; Relative Humidity in Death Valley, by A. G. McAdie ; and Tornado in 

 Western Montana, by R. F. Young. 



Meteorological reports, C. C. Geobgeson (Alaska Stas. Rpt. 1912, pp. 89-96), — 

 This is a summary in the usual form of observations on temperature, precipita- 

 tion, and weather conditions at the different Weather Bureau stations in 

 Alaska. 



Meteorological observations at the Massachusetts Agricultural Experi- 

 ment Station, J. E. Ostbander and E. K. Dexter (Massachusetts Sta. Met. 

 Bills. 295, 296, pp. 4 each). — Summaries of observations at Amherst, Mass., on 

 pressure, temperature, humidity, precipitation, wind, sunshine, cloudiness, and 

 casual phenomena during July and August, 1913, are given. The data are 

 briefly discussed in general notes on the weather of each month. 



Meteorological record (New Hampshire Sta. Bui. 163, pp. 39-64)- — Sum- 

 maries are given of daily observations at Durham, N. H., on temperature, pre- 

 cipitation, direction of the wind, and cloudiness for each month from July, 

 1910, to June, 1912, inclusive, as well as a summary by months for the period 

 from July, 1895, to June, 1912, inclusive. The average annual temperature for 

 that period was 45.4° F., the rainfall 40.76 in., the number of rainy days 98, 

 the depth of snowfall 55.4 in. 



Ohio weather in 1911, J. W. Smith and C. A. Patton (Ohio Sta. Bui. 249, 

 pp. 805-898, figs. 72). — The temperature and precipitation throughout the State 

 during each month is shown in 72 charts. The usual summai-y tables show 

 temperature and rainfall at Wooster and throughout the State (1SS8-1911). 

 For the first time tables of rainfall at the district test farms at Strongsville, 

 Germantown, and Carpenter are included in this summary. 



The mean temperature for the year at Wooster was 50.8° F., for the State 

 52.6° ; the highest temperature at the station was 101°, July 4, for the State 

 107°, July 4; the lowest temperature at the station was —11°, January 4, for 

 the State —19°, January 4. The annual rainfall at the station was 47.15 in., 

 for the State 42.65 in. The number of rainy days at the station was 142, for 

 the State 127. The prevailing direction of the wind was northwest at the

The water resources of the coastal plain of North Carolina, L. W. Stefhen- 

 soN and B. L. Johnson (N. C. Geol. and Econ. Survey [Rpt.], 3 (1912), pp. 

 ^lSS-483, pis. 14, figs. 5). — This is an extended discussion by counties of the 

 character of the surface and underground water supplies of this region, taking 

 up in considerable detail the question of artesian water. Analyses of many of 

 the principal waters accompany the report. 



Water (Bien. Rpt. Utah Conserv. Com., 1 (1913), pp. 106-131, pis. 6).— This 

 calls attention to the extent of irrigable land in Utah and reports on Carey Act 

 and private irrigation projects, and on the available ground and run-off water. 



Parm water supplies, with special reference to dairy farms, S. C. Peescott 

 (Amer. Jour. Pub. Health, 3 (1913), No. 9, pp. 892-902) .—Attention is directed 

 to the many sources of pollution of rural water supplies, especially surface and 

 shallow supplies, and a brief review is given of chemical and bacteriological 

 methods of analysis. Of 202 water supplies examined by the author from 

 dairy farms in a region " rather superior hygienically to rural districts of most 

 of the country " 29 were badly polluted and 10 gave evidence of immediate 

 danger of contamination. Various means of reducing the chances of infection 

 of farm water supplies are discussed.
