ence upon the physical condition of the soil, causing it to show a 
decided tendency to puddle and become hard. Whether this was 
due to the nitrate itself or to other salts formed from the nitrate as 
has been suggested I do not know. The number and size of the 
leaves on the nitre beets was larger than it is usual to find on sugar 
beets, besides, owing to the fulness of the foliage it was erect and 
not spreading or prone as we sometimes see it. The nitre beets 
did not seem to be so seriously attacked by the leaf-spot as the beets 
on adjacent land, but on counting the dead leaves on quite a number 
of beets to determine this point, I doubt whether there is any greater 
resistance shown toward the attack of the*' leaf-spot by nitre beets 
than by others. These beets were sprayed five times with standard 
Bordeaux mixture but I could see no conclusive evidence of benefit 
therefrom. The shape of the beets produced on these plots showed 
a decided modification of their form—as one effect of the nitrate. 
The beets became shorter and broader at the top as the nitrate ap¬ 
plied increased. The photographs of some of the piles as they lay 
in the field at harvest time show this effect. I do not think that the 
shape of the beet was modified in this way by the hardness of the 
soil, for I have seen well shaped beets dug from harder soil than 
any of this, still the hardness of the soil may have had some influ¬ 
ence, but I think that the full, excessive foliage and abnormal nutri¬ 
tion produced this effect. We have shown some photographs of 
beets grown on the College farm with excessive foliage and but 
seven tons of topped beets per acre. The following plates, Plates 
II and III, show some piles of beets as they lay on Field 2, 3, 5 and 
6. The differences are evident without further description. Field 
6 received no nitrate, fields 2, 3 and 5 received 500, 750 and 1,250 
pounds respectively. These fields form one continuous piece of 
land. We shall discuss the ashes and juices of these beets in subse¬ 
quent paragraphs. 
The plates representing beets grown with and without the appli¬ 
cation of nitrates show very marked differences, but the beets as 
they were harvested and lay in the fields showed the differences even 
more markedly than the photographs of these piles. The variety 
of beets represented is the Original Kleinwanzlebener and there is 
no question of varietal differences. There were some variations in 
the quality of the soil but the differences in the shape of the beets 
varied with the amount of nitrogen applied and not with these. The 
cultivation, irrigation, spraying, etc., has been given in sufficient 
detail and as may be seen were essentially the same. 
In order to present the extreme effects of nitre-impregnated 
land upon the shape of the beet I have introduced Plate IV. The 
lower photograph represents beets grown near Fort Collins, whose 
composition is given in Analysis VIII. The upper figure represents
