Deterioration Sugar Beets Due to Nitrates 35 
is very difficult to determine what we should adopt as a standard 
beet. This is a small matter so far as the percentage of sugar is 
concerned because the differences are so great and the average sugar 
content of the beet, as it now grows in the Arkansas Valley, is so 
much lower than it was six and ten years ago that all will agree 
that the beets are poor in this respect whatever standard may be 
adopted. The matter is not so easy when it comes to the question 
of composition. It is evident that, for my purposes, I can scarcely 
take Colorado grown beets, on the other hand foreign beets, viz: 
German beets, grown under entirely different conditions of cultiva¬ 
tion, soil, and climate, can not safely be adopted, even though the 
beets may have been grown from the same strains of seed. We 
shall very largely use German data, because it is the best to which I 
have access, but this will not relieve me from the necessity of using 
certain beets as standards of comparison. I have chosen one sample 
of beets from Michigan, one from Montana and one from the Poudre 
Valley, Colorado, for this purpose. The latter probably represents 
the highest grade of Colorado beets. 
The following German data are taken from an article by K. 
Andrlik, Zeitschrift des Vereins der Deutschen Zuckerindustrie for 
1903, pp. 9°6-937- The analyses are of fresh cossettes.
