ii2 The Colorado Experiment Station 
in the Valley during the past eight years. This was carried out on 
a sufficiently large scale to show what we had actually accomplished 
in this direction. The beets were treated in all respects just as they 
are in any factory, sliced, subjected to diffusion, a thin juice pro¬ 
duced, which was treated with milk of lime, carbonated, etc., and 
finally evaporated to a thick juice; but none of the samples were car¬ 
ried farther than this point except as will be given later. The dried 
cossettes and these thick juices were subjected to examination with 
the following results, which were kindly furnished me by Mr. W. H. 
Baird, at that time the General Superintendent of the American 
Beet Sugar Company. The analytical work was done by Dr. 
Potvliet. The designation of the fields is the same as in the preced¬ 
ing tables.

The technical results agree very well with those obtained by the 
analysis of our field samples. Field No. 6 was intended to be a 
check field but as elsewhere stated it failed us. The technical re-
