During the preceding year seven varieties of sugar beets have been cultivated on the college farm under the supervision of Professor Foster who has furnished the data concerning the preparation of the soil and the care of the crop. In the spring the ground was manured with well-rotted barn-yard manure at the rate of 100 cubic yards per acre. In May the ground was plowed 9 inches deep without subsoiling. Before the beets were sown the land was thoroughly pulverized by means of the harrow and after sowing the ground was rolled. The beets were not planted in ridges but the ground was left as nearly level as possible. The seed of three varieties, Vilmorin's Improved, Lane's Improved and the White Sugar beet was purchased of J. C. Vaughn & Co., Chicago. The seed of the other four varieties was obtained from the Sioux City Seed and Nursery Co.
