nitrogen supplied gradually diminishes — in this case from .40 to 
.20 pounds per inch of rain. 
Table II is a monthly record of precipitation and it presents a 
few noteworthy features. 
There is a gradual increase in the number of inches of precipi- 
tation from October, with .50 inches, to June, with 4.60 inches 
for the first half of the month. 
Beginning with February, there is a gradual increase of total 
nitrogen in parts per million — .699 to 1.134. This, with the in- 
creased amount of rain in inches, furnishes an increasing supply 
of nitrogen per acre to the soil during the main growing season. 
The increase in pounds per acre during this period is from .3057 
in November to 1.3078 in June. 
The 45 inches of snow supplied 13 per cent of the total 5.2790 
pounds of nitrogen per acre, or .6911 pounds. The rain supplied 
87 per cent, or 4.5879 pounds per acre. The rain is thus found to 
be richer in total nitrogen content than the snow. 
The work of Messrs. F. T. Shutt and R. L. Dorrance, mentioned 
above, has been of assistance in summarizing results.
