The Colorado Experiment Station 
stood at a hight of 36 inches on 8 Aug., and were erect because they 
were so abundant that they could not spread out. The color was 
a bluish green. The yield according to the factory returns was 
14.14 tons per acre. We took three sets of samples, 39 individual 
samples in all. The analytical results are quite consonant in the 
indications relative to the quality of these beets throughout the sea¬ 
son. We will again use the Montana beet as standard because we 
consider it the best beet that we have analyzed and is the only one 
that we have found entirely free from nitric nitrogen, though a 
Fort Collins standard beet contained only 0.0009, a ver y small 
amount. The following tabular statement presents the principal 
features in the composition of these beets:

These results are identical in kind with those produced by the 
sodic nitrate but much greater in degree, but not at all in proportion 
to the amount by which the nitric acid in this soil exceeded that 
applied in our experiments with the nitrate. We find that we 
reached our maximum effect with 1,000 pounds of nitrate applied 
in four portions. One thousand pounds nitrate applied per acre 
would add but 83 p. p. m. of nitric nitrogen provided it were uni¬ 
formly mixed with the surface six inches of soil which we here 
consider as weighing 2,000,000 pounds. We have as a matter of 
fact on 22 June, 70 p. p- m. in the top four inches of the soil in the 
best part of this field, and 405 p. p. m. on this date in the worst por¬ 
tion of the field taken to the same depth. The best portion of these 
plots reaches a hight of 18 feet above the worst portion. The beets 
from the first section of the check, the best section, have a composi¬ 
tion very similar to that of those grown with 750 pounds of nitrate 
applied in three portions which corresponds to 62.5 p. p. m. nitric 
nitrogen, calculated on the top six inches of soil. We place these 
results side by side that the similarity may be easily seen. The fig¬ 
ures are all calculated on the fresh beet or on 100 of sugar.
