 570). — Tables are given showing tridaily readings at Geneva. N. Y., of standard 

 air thermometers for each month of the year; daily readings of maximum and 

 minimum thermometers at 5 p. m. foi' each month of the year ; a monthly sum- 

 mary of maximum, minimum, and standard thermometer readings; average 

 monthly and yearly temperatures since 1SS2; monthly and yeai'ly maximum 

 and minimum temperatures from 1883 to 1909, inclusive; and rainfall by months

Weather summary, L. R. Waldkon (North Dakota Sta., Rpt. Dickinson Bub- 

 sta. 1910, pp. 83-85). — Tables give data for the Dickinson substation as to evapo- 

 ration and pi-ecipitation during the growing seasons of 1907 to 1910, the monthly 

 precipitation and temperature 1906 to 1910, and dates of early and late frosts 

 during the same period. 



Meteorolog'ical summary for 1909, C. A. Patton (Ohio Sta. Bui. 220, pp. 

 6-'il-659). — This summary includes as usual notes on the weather of each month 

 of the year and tabulated daily and monthly records of observations at the sta- 

 tion at Wooster, Ohio, on temperature, precipitation, cloudiness, and direction 

 of the wind, and for comparison, similar data for 22 pi'evious years (1888- 

 1909) at the station and for 27 years (1883-1909) in other parts of the State. 



The mean temperature for the year at Wooster was 50° F., for the State 

 50.7° ; the highest temperature at the station was 90°, September 14, for the 

 State 97°, July 30; the lowest temperature at the station was — 11°, January 

 13, for the State —20°, December 30. The annual rainfall at the station was 

 44.22 in., for the S-tate 42.32 in. The number of rainy days at the station was 

 144, for the State 124. The prevailing direction of the wind was southwest at 

 the station and for the State. 



Moisture studies in corn and wheat plats, L. R. Waxdeon (North Dakota 

 Sta., Rpt. Dickinson Substa. 1910, pp. 60-76, dgms. 7). — The moisture content 

 under corn and wheat grown on spring-plowed, fall-plowed, summer-fallowed, 

 and cropped soils was determined at different dates from November, 1909, to 

 October. 1910. 



Summer fallowing increased and continuous cropping decreased the moisture 

 content of the soil. Spring-plowed soil contained less moisture than fall-plowed, 

 but no very definite relatiou between yields and moisture content was estab- 

 lished. The moisture content to a depth of 10 ft. was nmch smaller in the 

 wheat plats than in the corn plats. 



The amount of water used by corn crops during 4 years plus the amount 

 found in the soil at the end of the period was about 41 in. The amount used 

 by the wheat crop under like conditions was 46 in. As the rainfall during the 

 period was about 80 in., the loss of water was from 55 to 60 per cent, the loss 

 being greater in the case of the corn plats than in that of the wheat plats. The 

 greater loss in the case of the corn was due to the sinking of the water to a 

 greater depth than 10 ft.
