be 3 or 4 per cent too high, but the figures represent very closely condi- 

 ditions at Chillicothe. 



The data for Bard were taken from the Weather Bureau records for 

 Yuma, Ariz., which is only 7 miles distant and is practically the same ele- 

 vation as Bard. 



The data as given for Chula Vista, Cal., are taken from the Weather 

 Bureau records at San Diego, Cal., which is 12 miles from Chula Vista and 

 similarly located in respect to its proximity to the ocean. 



There were no complete weather records for Puyallup, Wash., at any 

 point nearer than Tacoma, Wash., 8 miles distant, but since these two 

 places are very similarly located, it is believed that the data from Tacoma 

 represent conditions at Puyallup closely enough for the purposes of this 

 study.
