periment were excellent, the average weight per beet of the 200 sam¬ 
ples being twenty-seven ounces, or 1.7 pounds. 
The sugar content and purity of the beets analyzed were in gener¬ 
al satisfactory, and about as high as the average of the district this 
season (1905). Both the sugar content and yield of sugar beets were 
somewhat below the average of previous seasons in Northern Colo¬ 
rado and elsewhere, largely due to the late spring and copious rains in 
the earlier part of the growing season, which caused a more luxur¬ 
iant growth of tops or leaves than usual, but which proved rather un¬ 
favorable to the production of a proportionate increase in weight of 
the sugar beet crop. 
RESIDUAL OR AFTER EFFECTS OF MANURES AND FERTILIZERS 
Experiments on Field F, 1903-4-5. —From the plats on Field F, 
to which manures and fertilizers were applied in 1903 , the data of 
which is given in Table 5, the beets were harvested separately and 
other data secured in the following two years in order to determine 
the residual or after effects of the manures and fertilizers used. Some 
very interesting facts were disclosed, that data being given in Table 
11 .
