plenty of water, and that beets grown on light and sandy lands are 
more susceptible to the influence of this condition than those grown 
on heavier lands. It is possible that the lightness of the land on 
which the beets of Analysis XX were grown may have detrimentally 
influenced their composition, but it was not due to a scarcity of 
water. The injurious nitrogenous substances for each ioo pounds 
of sugar in these samples were respectivey 7.5 and 10.72, the latter 
of which is a larger quantity than we find in the beets grown with 
fertilizers which show 9.46 and 9.55 parts as maxima. While the 
injurious nitrogen in the beets grown on the fertilized plots is un¬ 
doubtedly high and was probably increased by the fertilizers used, 
it is not safe to conclude that these beets were lower in quality than 
beets grown on other lands without the application of fertilizers, for 
this seems not to be the case. The total nitrogen in the analyses so 
far given, made to include the nitric nitrogen, is not high. The 
total nitrogen in Analysis XXX may be considered as exceptionally 
low and neglected, still the total nitrogen in the other samples is not 
high; On the contrary it is lower than the analyses quoted from 
Andrlik and, as a rule, lower than the few determinations of total 
nitrogen that I have found given for beets in general. So far I 
have given twenty-one analyses of Colorado beets, in only five has 
the total nitrogen amounted to 0.2 percent and the maximum is 
0.252 percent. Of the five samples showing 0.2 percent or more of 
nitrogen only one was a good beet, i. e., the one grown near Fort 
Collins, the others were all poor beets. These twenty-one samples 
of beets were grown both with and without the application of fertil¬ 
izers. The total nitrogen in these samples is low rather than high 
and the ratio of the proteid nitrogen as determined by Stutzer s 
method, to the total nitrogen is often quite low, though the proteid 
nitrogen given by this method is apt to be too high. In the samples 
quoted from Andrlik, we find this ratio higher. It is as follows 
for the six samples given:

Andrlik makes no 
comment on 
the quality of these beets ex 
cept to say that No. 5 is a bad beet while No. 6 is a good one. The 
data here given do not agree exactly with Andrlik’s. He gives for 
the injurious nitrogen 0.930 instead of 0.828 and 0.37 instead of 
0.409. Concerning the intermediate beets he makes no classifica¬ 
tion so we are left to determine where the dividing line between good
