INTRODUCTORY. 
PREVIOUS WORK OF THE STATION ON SUGAR BEETS. 
§ 1. This Station has already published nine bulletins on the 
subject of sugar beets, seven of which have been devoted to the 
demonstration of the fact that remunerative crops of sugar beets can 
be grown in the irrigated sections of this State up to altitudes of 7,800 
feet. The earliest experiments recorded, 1888, show a trifle over 
12 per cent, of sugar as the maximum per cent, present in any of 
the varieties experimented with. The only object aimed at in the 
experiments of that year seems to have been to determine whether 
the beet could be successfully cultivated under our conditions. The 
results were most encouraging, both in regard to the percentage of 
sugar present in the beets and also the tonnage, which ranged from 
24 to 30 tons per acre. This yield was estimated from the product 
of an average row 450 feet long. 
§ 2. The experiment of 1888 was not continued in 1889, but 
another line of work was undertaken, namely, to study the effect of 
various soils upon the composition of the ash, the percentage of the 
sugar, and on the feeding value of the beets. The results of this 
investigation were published in 1890 as Bulletin 11. 
* Part I., forming Bulletin 46 and issued in 1898, is out of print. Most of the reports of 
l he Station have something about sugar beets. Of the bulletins treating of sugar beets, none but 
36, 51 and 57 can be supplied, except to libraries. Those printed are as follows :
