Analysis XX 
represents 
beets grown on a 
favorably 
r located 
piece of land, a rather light sandy loam. 
This land lies immediately 
west of that on w 
hich we made the experiments 
with sodic nitrate 
and the sample was taken less than 200 feet west of the west end of 
our experimental fields. The sample was taken, because the sam¬ 
ples taken from our check field on 23 Sept, and 11 Oct. revealed the 
fact that they were not consistent with themselves and that our sec¬ 
ond sample from Field 5 and first sample from Field 6, though taken 
about 54 feet apart, agreed much more nearly than the two samples 
from Field 5, which were taken within 27 feet of one another and 
had received 1,250 pounds of sodic nitrate per acre, whereas Field 
6 had received none. 
We attempted to determine the nitric nitrogen in Field 6 at 
stated intervals throughout the season. the field was reported 
flooded on 6 July and so wet on 10 Aug., eleven days subsequent to 
the last preceding irrigation, that samples could not be taken. I 
feared that the results obtained with the samples from Field 6, 
which lay a little lower than Field 5, might have been due to acci¬ 
dental causes whereby the beets might have been supplied with 
nitrates carried from the adjacent, higher-lying portion of Held 5- 
This may not have been the case but the results led me to fear that 
it might be, so I took the sample represented by Analysis XX, which
