INTRODUCTORY. 
By the Director. 
Since 1889 the Colorado Experiment Station has issued ten 
bulletins relating to sugar beets, eight of which have been devoted 
entirely and two partially to the study. Nearly all of these bulle¬ 
tins are now out of print, but demands still continue for the infor¬ 
mation contained in them. It is not desirable to reprint these 
bulletins, yet man}^ of the investigations and conclusions are still 
pertinent, and it is believed that a summary of these bulletins to 
render the results accessible will be of much use, and incidentally 
serve to maintain the credit of the Station for the pioneer work on 
this subject which it has done in this State, the extent of which is- 
realized by few. The bulletin places the facts developed in the pub¬ 
lished reports of this Station in compact form, and while attempting- 
to summarize our own publications referred to, it does not attempt 
to summarize the work of the other stations or of the Department of 
Agriculture on the same subject. 
This early and continuous work of the Station carried on since 
1888, and supported in 1898, as it has been, by various interests, 
especially of the Denver Chamber of Commerce and the C. & S. It. R., 
has been an important factor in the location of the industry in Colo¬ 
rado on a firm foundation. These investigations have given the 
data necessary in order that sugar beet factories should be justified. 
At this time three factories (Grand Junction, Rockyford, and Sugar 
City) are in operation in the State. Another (at Loveland) is in ac¬ 
tive construction, and several more are in contemplation for 1902.. 
The industry has every promise of being of much importance to the 
State, and especially valuable as it does not interfere with any other. 
The results already reached show that it finds in Colorado, as has- 
been indicated in the early reports of the Experiment Station, a 
state well adapted to the industry.
