“The former amount indicates a good, the latter a bad diffusion 
juice." It is further shown in the same article that 92.3 percent of 
the injurious nitrogen and from 70.9 to 80.3, usually 75.3 to 79.9 
percent, of the injurious ash of the beet goes into the diffusate. 
In 1910 I endeavored to obtain beets as standards for compari¬ 
son with ours which we knew to be good beets and which worked 
well in the factory, for these reasons we chose a sample from Fort 
Collins with 18.3 percent sugar and one from Michigan with 15.3. 
We found the injurious ash in the former to equal 2.197 P er 100 
sugar, in the latter 1.945, the injurious nitrogen to equal 0.629 and 
0.513 P er 100 sugar respectively and the ratio of proteid to total 
nitrogen 41.9 percent and 53.7 percent. In the press juice we find 
the albumin nitrogen forming 36.2 and 32.0 percent respectively of 
the total nitrogen. The injurious nitrogen in the beet constitutes 
55.5 and 34.3 percent of the total. The pure ash in the Michigan 
beet is approximately 83.33 percent of that in the Fort Collins beet. 
These are the principal feature in the composition of these beets, but 
it may be permissible in this place to state that the pure ash in these 
beets, 0.6088 and 0.4930, is quite within the range that I find given, 
especially by Andrlik, for Austrian or Bohemian beets. The points 
of interest in these ashes are that the phosphoric acid calculated on 
the fresh beet is fairly high, the potassic oxid is very high, which is 
the case with the magnesic oxid also, while the calcic oxid is low. 
The nitrogen is almost identical with the average found for German 
beets over a period of seven years bv the Experiment Station of 
Lauchstaedt, but according to other figures I find that over 50.0 
percent of the samples fall below 0.2 percent. The chlorin in these 
samples is quite low. 
In 1911 a favorable year, I was fortunate enough to obtain 
through the kindness of Mr. Hans Mendelson of the Great Western 
Sugar Company a sample of beets grown by himself in Montana. 
The variety was a strain of his own production, No. 311, and had 
been siloed for three months or more before it was sent to me. Mr. 
Mendelson has kindly furnished me the following data relative to 
the cultivation of these beets. “The land is a sandy loam, had been 
planted to grain for eight years in succession up to 1909. In 1910 
was planted to field peas, after harvest the field was disced, irrigated 
and sown to rape. This was pastured off in the fall by sheep and 
in the spring handled in the usual manner. The rows were 20 
inches apart and the beets 8 inches apart in the rows. The growing 
crop showed every indication of a lack of nitrogen, still a fertiliza¬ 
tion with 200 pounds of nitrate did not produce the expected in¬ 
crease, indicating some other deficiency, in this case a lack of mois¬ 
ture in the subsoil.” 
These beets were of excellent shape and varied considerably in
