Table 70 shows that the average temperature of all the soils was 

 highest in summer and was followed in order by autumn, spring and 

 lastly by winter. The temperature of all the different soils was some- 

 what different at the various seasons, with the greatest variation occur- 

 ring in the spring and the least in the winter. In the spring and sum- 

 mer seasons the soil with 3.32% organic content exhibited the highest 

 temperature at both depths, with the soils containing 2.08, 5.47, 0.95, 

 1.81% and peat came next in order. In the fall season, with the excep- 

 tion of the soil with 1.81% organic matter, the temperature was prac- 

 tically the same for all the other soils. For the winter season the soil 

 with 1.81% organic niattor had the lowest temperature and the peat 

 the highest, while the temperature of the soils with 2.08, 3.32, 5.47 and 

 6.95% organic matter was intermediate and about the same for all of 

 them. When the averages for the year are examined, it is found that 

 the temperature of the soil with 1.81%. organic matter and that of peat 

 was almost the same but less than that of the soils with the intermedi-
