The winter being quite mild, a fair growth was made. Samples taken April 2 gave the following results: Average weightoi beets dug, ounces; yield per acre, tons; sugar in beets, per cent; purity .co-efficient, per cent. These are probably as good results as could ordinarily be expected from seed sown on the earliest practicable autumn date. At the close of the year 1899 bulletin 31 was issued giving the result of the year's work. The averages from ten plats sown during January and February, 1899, were as follows: Yield per acre, tons; per cent sugar in beets, ; purity, 77,7; avail- able sugar per acre, 2010 pounds. The most important of the conclusions from the work of the year was that winter-sown beets are not benefited, and may be injured, by early irrigation, pro- vided the soil has been thoroughly irrigated previous to seeding. The indications were that the most advantageous time to begin irrigating is when the beets are two to three months old. A plat sown December 26 and first irrigated April 1 gave the following results: June 15. July 1. July 11 July 30. The yield upon the latter date was tons per acre, giving an approximate yield of available sugar per acre of 4050 pounds, the highest yield yet obtained from any of the experimental plats during the past four years. This yield of sugar per acre evidently remained about constant during all of June and July, the increase in the percentage of sugar being just about counterbalanced by a decrease in the purity coefficient. Only a tenth of an inch of rain fell upon the plat from the time of seeding until the first irriga- tion over three months later, during which period they made an excellent growth. This result was accomplished by a thorough irrigation of the soil previous to seeding. A plat sown January 23 and first irri
