But one other factor remains to be noticed in regard to 
the ripening of the crop. All of the beets in northeastern 
Colorado were grown from seed imported from Germany. 
The experiments conducted at Lehi, Utah, make it probable 
that by using seed grown in the United States at five thous- 
and feet altitude the ripening of the crop is hastened from 
a week to ten days. 
In view of all the foregoing statements, we have a right 
to conclude that whenever a factory is actually built in 
northeastern Colorado, it will find beets ready for manu- 
facture soon after the middle of September. 
After what has been said of the ripening of beets in 
northeastern Colorado, there need be but little said con- 
cerning the other portions of the state. The same principles 
govern the ripening everywhere. On the Divide, south of 
Denver, where beets are grown without irrigation, the crops 
matured somewhat later than in the valley of the Platte, 
with irrigation. The content of sugar reached thirteen per 
cent by the first of October, but the purity was then too low 
for manufacturing purposes. By the middle of the mxOnth 
the beets were all right for the factory. 
The Arkansas Valley is one hundred and fifty miles 
south of that of the Platte and as a natural result frosts hold 
off late and the beets are late in ripening. Had a factory 
started up October 15, it could probably have found beets 
enough to keep it running, but the bulk of crop was 
hardly in marketable condition before the first of November. 
On the other hand, the winters here are so open and mild 
that there would be little trouble in a factory running all 
winter or until the crop was all handled. 
The analyses from the valley of the Grand show that 
the crops were easily ready for the factory by the first of 
October and probably several days earlier. The bulk of 
the crop was ready at least a week or ten days earlier than 
that of the valley of the Platte. The climate of the valley 
of the Grand is a little warmer than that of the Platte and 
hence it would be supposed that the crop would ripen later 
rather than earlier, ddie cause of this result must be due 
either to better care, or to different seed, and is probably 
due to both these causes, d'he farmers in this valley have 
been experimenting in the raising of sugar beets for several 
years, and many of them have made a careful study of the 
subject. Hence their fields were better cared for, the qual- 
ity of the crop was better, and it ripened earlier. 
The remaining section of Golorado is the San Luis val- 
ley. The analyses from this section are so mixed that it is
