0.02138. Injurious ash per 100 sugar was 3.4164, and injurious 
nitrogen 0.6384. The beets grown in a part of the same field in 
1911 were much better in every respect except that the phosphoric 
acid yras much lower. This difference was not due to the date of 
harvesting, for the one was gathered on 11 Oct., the other on 12 
Oct. When we pass to ordinarily good land in the Arkansas Valley 
and consider the quality of the beets grown on such land without 
any fertilizers we find low percentages of sugar and dry substances, 
high ash, low phosphoric acid, often high chlorin, high potash 
(alkalis), variable total nitrogen, high nitric nitrogen and large 
amounts of injurious ash and nitrogen per 100 sugar. Analyses 
XX and XXVII represent beets grown on good land but of sur¬ 
prisingly poor quality. This land was a sandy loam; the water 
supply in 1910 was good throughout the season and the cultivation 
was also good. The beets suffered some from leaf-spot, no fer¬ 
tilizers used. The percentage of sugar in the sample taken 3 Nov. 
was 12.7 percent; of dry substance 20.0, pure ash in beet 0.7176, 
phosphoric acid 0.03825, chlorin 0.03342, sodic oxid 0.17585 after 
deducting enough to combine with the chlorin present, total nitro¬ 
gen 0.25215, nitric nitrogen 0.04537, injurious ash per 100 sugar 
3.703 and injurious nitrogen per 100 sugar 1.07246. There is neither 
seepage nor alkali, as we usually use this term, in this land. The 
beets did not suffer from drought nor were they injured to any ex¬ 
tent by the leaf-spot and yet the contrast between these and good 
beets is marked in every respect. I do not know the variety of these 
beets. Compared with either one of the samples, especially with 
the Montana beets, they yield very interesting results. The figures 
for the Montana beet are given first; sugar 18.24-12.7; dry matter 
25.37-20.00; pure ash in beet 0.4909-0.7176; phosphoric acid 
0.08117-0.03825; soda 0.01312-0.17595 ; total nitrogen 0.10494- 
0.25215; nitric nitrogen 0.0000-0.04537; injurious ash per 100 
sugar 1.67240-3.7030; injurious nitrogen per 100 sugar 0.16722- 
1.07246; ratio proteid nitrogen to total nitrogen in press juice 53.0 
percent—20 percent. We can almost exchange these figures for 
the Colorado sample throughout for those obtained in the case of 
beets grown with the application of 750 pounds of nitrate per acre— 
in other words, the results are not only identical in character but 
almost identical in.extent. 
We have just placed in juxtaposition the results obtained with 
the very best beets that I have analyzed and a very poor sample of 
beets grown on good land and under favorable conditions—the one 
factor, the presence of leaf-spot, excepted. We look upon the re¬ 
sults obtained by defoliating the beets as having already eliminated 
this. We can, however, eliminate it still more effectively and at 
the same time show that we have other recourse than the compari-
