Numei'ous correlations between both temperature variations and rainfall at the two 

 places are shown. The utilization of observations at the more elevated point in local 

 forecasts is explained.

WATER— SOILS. 



The fruit soils of Virginia, W. B. Alwood ( Virgima Sta. Bui. 

 98,2>p- ^9-1^,1, map 1). — This is a compilation of available information 

 on this subject, including the author's observations, and deals mainly 

 with the economic phases of the question. In discussing the subject 

 the State is divided into 6 natural divisions, viz: Tidewater, middle 

 Virginia, Piedmont, the Blue Ridge section, the valley, and Appalachia. 

 A map showing the extent of these different divisions, and the location 

 of areas known to be adapted to pippin orchards, accompanies the 

 article. "It is hoped that this publication will mark the beginning 

 in the near future of a more critical study of certain phases of this 

 all-important subject to fruit growers."
