316 EXPERIMENT STATION RECORD. 



icrritocy siirroundiiic; lli(> (Jrc;it Lnkes whore :i( ncnr-Iiy pdiiils llio lonsth of the 

 frostless season may differ by from 25 to r»0 days. Also along the Atlantic 

 coast in southern Now Enf^land, over I.onjj; Island, and in the vicinity of Chesa- 

 peake Bay the growing season is as long as in Tennessee, hundreds of miles to 

 the southward. 



" Likewise may be seen the increased probability of frost and the consequent 

 shortening of the growing season on the elevated level plateaus, notably in the 

 Berkshire Hills of New England, over the plateau of western New York and 

 north-central Pennsylvania, in the Cumberland Plateau, and in the highlands 

 of Wisconsin and northern Michigan." 



Meteorological record {ISleiv Hampshire Sta. Bui. 151, pp. }f9-'12). — 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, 1908, 

 to June, 1910, inclusive. 



Division of meteorology, N. Helme (Rhode Island Sta. Rpt. 1910, pp. 

 366-383). — -Daily observations at Kingston on temperature, precipitation, wind, 

 and cloudiness for each month of the year ended June 30, 1910, are summarized 

 in tables and notes. The mean annual temperature was 48.6° F. ; the maximum 

 93°, August 8, 1909; the minimum — 7°, January 5 and February 7, 1910. The 

 annual precipitation was 43.71 in., the number of clear days 158, and the pre- 

 vailing direction of the wind west. The year was characterized by very dry 

 weather in July and August, 1909. The last frost was observed June 5, 1910. 



Bulletin of the Mount Weather Observatory ( U. 8. Dept. Agr., Bui. Mount 

 Weather Observ., 3 (1911), pt. 5, pp. 275-346, figs. 36, charts 6).— This number 

 contains the following articles: On the Relation Between Atmospheric Pres- 

 sure and Wind (illus.), by J. W. Sandstrom ; and Free Air Data at Mount 

 Weather for October, November, and December, 1910 (illus.), by W. R. Blair. 



Meteorology, practical and applied, J. W. Moore (London, 1910, 2. rev. and 

 enl. ed., pp. J,92 ; rev. in Lancet {London^, 1910, II, No. 26, pp. 1837, 1838).— 

 This is a second revised and enlarged edition of this well-known treatise, which 

 in its new form is thoroughly up-to-date. 



The South's rainfall and temperature in relation to southern agricultural 

 monopolies, W. A. Withers (Tradesman. 65 (1911), No. 11, pp. Jf4, -'i5). — The 

 relation of rainfall and temperature to the production of cotton, tobacco, rice, 

 sweet potatoes, sugar cane, and peanuts in the South is discussed. It is shown 

 that conditions of rainfall and temperature are especially favorable to the 

 production of these crops in different parts of the South. 



The climate of Hungary, S. Rona (Met. Ztschr., 28 (1911), Nos. 1, pp. 

 16-28; 2, pp. 5.5-66).— This is a summary of a large work in two volumes on 

 this subject published in the Hungarian language. 



Underground water papers, 1910 (U. >Sf. Oeol. Survey, Water-Supphj Paper 

 No. 258, pp. 123. pis. 2, figs. 32). — This paper contains a series of short articles 

 rejiorting the results of special or subordinate investigations as follows: 



Drainage by wells, M. L. Fuller (pp. G-22). — The emptying of sewage and in- 

 dustrial wastes into drainage wells is condemned, but the drainage of most 

 ponds and swamps into wells is considered unobjectionable. 



The freezing of wells and related phenomena, M. L. Fuller (pp. 23-31). — It is 

 shown that the freezing of wells is due to access of air to the pipe at consider- 

 able depths and not to transmission of cold outside air through the casing, and 

 that methods of protection which do not recognize this fact fail. 



Occurrence and composition of well waters in the slates of Maine, F. G. Clapp 

 (pp. 32-39). — Investigations reported show that plenty of excellent water can be 

 found in most of the metamorphic slates of Maine, generally at depths of from 

 200 to 300 ft. The deeper wells are safer from pollution.
