The amount of moisture which is shown in the 

 table was determined at the end of 6 3/4 days for plat 

 22a, 9 3/4 days for plats 1, 4, 2, 3, 5, and 23, and at 

 the end of 13 days for plats 7, 10, 16, 19, 22, 25, and 9. 

 By inspection of the table it will appear that the selec- 

 tion of the points for which the calculations were made 

 was slightly arbitrary. It would seem probable that the 

 level was reached in some cases between the dates at which 

 the data was taken. But the closeness of agreement^ the 

 per cent^ moisture as calculated from this data with the 

 moisture in the field July 9th. when the moisture was 

 supposedly about the optimum indicates^ that this is a 

 fairly dependable method at ^tUW- in this soil, not- 

 withstanding its variations, for the determination of the 

 optimum moisture content. After the loss continued on 

 the "fairly uniform level" for some time the rate of loss 

 began to decrease slowly at first, then rapidly. The 

 moisture in the soil just before the most marked fall 

 occurred is calculated and showij in Table " J" .
