and 5.7 parts injurious nitrogenous compound per 100 parts sugar. 
While this is lower in sugar than our adopted standards with 15.3 
and 18.3 it is almost as low as the lower one of them in injurious 
nitrogen. Analysis XVIII indicates a decidedly poor beet, while 
analyses XIX and XX are decidedly poorer still, particularly 
analysis XX, which is both low in sugar and rich in injurious nitro¬ 
genous substances, 10.7 parts per 100 sugar. 
It appears from these samples that excellent beets can be pro¬ 
duced in widely separated sections of the state but as a fact our soils 
do not uniformly, even under favorable conditions, produce beets of 
good quality, but on the contrary some of them are of decidedly bad 
quality. In regard to the different forms of nitrogen present we 
observe that the nitrogen precipitated by Stutzer’s reagent, even 
though we know that it may carry down some amids, is low, whether 
we calculate it on the fresh beets or on the total nitrogen. The am¬ 
nionic, amid and amino nitrogen appears to have very nearly the 
same ratio to the total nitrogen as I find given by others for German 
beets. The nitric nitrogen, however, is present in all of the analyses 
in noticeable quantities. As already stated this form of nitrogen 
has been found in some abundance in French beets. The maximum 
which I have found is in an analysis quoted from Ed. Urban by 
Ruempler in which 25.25 percent of the total nitrogen was present in 
this form. Ruempler further states that Bresler found only from 
1.6 to 2.35 percent of the total nitrogen in the form of nitric nitrogen 
and that Herzfeld found in general only traces. We have in the Colo¬ 
rado and Michigan beets adopted as standards 0.46 and 1.4 percent 
of the total nitrogen present as nitrogen in the form of nitric 
acid; in analvsis XI we have it corresponding to 2.8 percent of the 
total, in XIII we have 6.0 percent and we find it increasing in the 
series of samples till in analysis XX it amounts to 18.0 percent of 
the total. None of these samples were grown on manured or fer¬ 
tilized land except XVIII and XIX; these had received ten tons of 
stockyard manure per acre, which had been plowed under to a depth 
of ten inches. Analysis XIX shows the presence of nitric nitrogen 
equivalent to 9.3 percent of the total. Perhaps Analyses XVIII 
and XIX should have been omitted from this list, but they represent 
a check plot, in our experiments with nitrates of which they received 
none, but owing to the peculiar results obtained with samples from 
this ground, Sample No. XX was taken, as already explained as a 
further control. 
We conclude that under favorable soil conditions the Colorado 
beet grown without the application of fertilizers is as good a beet as 
the beets of the other states or countries, that is that it contains as 
much sugar and as little injurious nitrogen. Concerning the injur¬ 
ious ash we are not so certain, for I have nowhere found any definite
