being present. The main question at issue in this work has 
been the effect of commercial fertilizers and stable manure upon 
the manufacturing value of the beets, with especial reference 
to the possibility of depressing the quality of beets by growing 
them on land to which stable manure has been freshly applied. 
A determination of the percentages of sugar and of the 
coefficients of purity has been the means of judging of the 
quality of the beets grown. No determination has been made 
of the character of the non-sugars present in the juice. If beets 
may be standardized as to quality by the proportion of sugar 
in them, together with the coefficient of purity, then the conclu- 
sions to be drawn from the data herewith presented are plainly 
indicated. Attention is directed to the figures of the preceding 
tables but more especially to the general summary in Table

The data here presented are strikingly opposed to what is 
regarded as the orthodox method of manuring sugar beet land. 
It so happens that, with the exception of the crop of 1901, not 
only does the stable manure fail to depress the quality of the 
beets, but the crops grown where it was applied in the spring 
show a higher percentage of sugar than where commercial ferti- 
lizer was used or where no manure was applied. In 1901 the 
percentage of sugar was but little lower but the coefficient of 
purity appeared to drop. In this case the stable manure was 
used in an excessive quantity.
