The average weight per beet of all samples analyzed is found to 
be 1.76 pounds, and the average fresh green tops 44.2, from 42 deter¬ 
minations of 12 samples each. The average yield of 19.8 tons will 
thus produce 8.75 tons of fresh green tops. 
The loss of weight in thorough air drying or curing has not been 
determined, but it is believed that one-eighth of the green weight 
would be a reasonable estimate. Calculating the green tops at 44.2 
per cent of the net weight of beets the relation of tons per acre and 
tops would be as follows:

Note— Tops on Plats 2 to 5 were allowed to remain on the ground from three 
to five days after topping. 
The data given in Table 15 was obtained by gathering and 
weighing all the tops of a known area, with yield of beets, from one 
to five days after topping. A considerable per cent was lost in this way, 
being impossible to gather. There was also considerable loss in 
weight from evaporation in those last gathered. It will be seen that 
the percent of tops from Plat 1 with an excessive amount of leaves 
by actually gathering all the tops, is greater than the figure obtained 
from the sample beets, the sample showing forty-one per cent and the 
gathered leaves fifty-one per cent of the beets harvested. 
Data in Regard to Maturing Period of Sugar Beets.—The data 
given in Tables 16, 17 and 18 was obtained in cooperative work with 
the Bureau of Chemistry, Department of Agriculture, Washington, 
D. C. All the analyses of 1902 were made by the Bureau, and that of 
other years in the laboratory of the local sugar factory by the courtesy 
of Mr. Booraem. 
The samples were taken every week beginning with the last week 
in September and continuing until the beets were all harvested or 
until prevented by freezing of the ground. The manner of taking 
the samples consisted of digging all the beets from a fifty foot row, 
each successive digging adjoining the other, counting, cleaning, par-
