The foregoing two tables show that the average air temperature was 

 above the soil temperature of all depths from April to December inclu- 

 sive, and below it during the months of January, February, and March. 

 While the range of the air temperature was far greater than that of 

 the soils and was above that of the latter throughout the year.
