large increase in the nitric nitrogen, ten times, a very decided in¬ 
crease in the injurious ash and nitrogen per 100 of sugar, 3.205 f° r 
the former and* 0.6822 for the latter. The diffusion juice from 
these beets showed a considerable reduction in its percentage of 
nitrogen and yielded a thick juice of 88.29 purity. 
With the application of 750 pounds of nitre per acre, the results 
were bad, crop 14.94 tons, sugar in beets 13.4, dry substance 20 
against 22 with 250 pounds, pure ash in fresh beets greatly in¬ 
creased, 60 percent, phosphoric acid reduced from 0.0375 to 0.03588, 
the alkalis increased, potash to 0.30088 and the soda to 0.18359, the 
total nitrogen increased from 0.14485 in the beets grown with 250 
pounds of nitre to 0.29610 in the beets, and 0.27065 in the juice, and 
the ratio of the proteid nitrogen to the total was very greatly de¬ 
pressed, to 16.9 percent in the juice, the nitric nitrogen increased 
from 0.00144 in the beets grown with 250 pounds, of nitre, to 
0.04 t 43. The real coefficient of purity of the thick juice produced 
from these beets was 86.66. 
The results obtained by the application of 1,000 pounds in four 
portions did not show a further reduction in the yield but the per¬ 
centage of sugar and dry substance in the beets were reduced to 11.0 
for the sugar and 17.6 for the dry matter; the pure ash in the beet 
was quite high, 0.7444, the phosphoric acid fell still further to 
0.02373, the total alkali was nearly 0.46 and the soda . rose to 
0.23728, the total nitrogen was high both in the beets and juice, the 
proteid nitrogen was low and the nitric nitrogen in the beet rose to 
0.06285 and the real coefficient of purity of the thick juice was 86.37. 
For some reason, as stated more in detail elsewhere, the plot 
which received 1,250 pounds in five applications and our check plot 
which lay alongside of it, gave us unexpected and discordant results. 
The general results, however, with 1,250 pounds per acre, were the 
same as those with 1,000 pounds, low percentages of sugar and dry 
substance, low percentage of phosphoric acid, high alkalis, especially 
soda, high total nitrogen, low ratio for proteid nitrogen, high nitric 
nitrogen, high amounts of injurious ash and nitrogen per 100 sugar, 
4.04 for the former and 1.115 1 f° r the latter. The real coefficient 
of purity of the juice from these beets was 86.43. Though, the re¬ 
sults obtained on our check plot, probably due to a flooding in eaily 
August which also involved a part of the field which had received 
the application of 1,250 pounds of nitrates, were altogether unsatis¬ 
factory, still the real purity of the thick juice from these beets was 
88.26, which is at least one point lower than it should be and stdl 
we see that the effect of 1,000 pounds of nitrate of soda per acre 
was to depress the coefficient of purity of the thick juice by 1.89 
points below this and hereby probably increased the molasses, which 
these beets would produce by from 3 to 4 percent on the weight of
