The period covered by the experiment was from May 1st to 

 Nov. 1st, with thermometers placed in the soil to the depths of 1, 

 3, 6, 9, 12, 24 and 36 inches. 



The location of the thermometers was in open field (near hygro- 

 meter No. 2) in the tract of land assigned to the Station for 

 expermiental purposes and devoted to farm experiments. The 

 character of the soil is regarded, therefore, as representative of 

 that on which the field experiments by the Station are carried on. 



A summary of results by monthly averages is given in the 

 annexed tables.
