good stund thus secured. If a press drill is used the ground is left level and in good condition for the mower. The depth of seeding has but little effect on the root system of Sudan grass. It seems to he a characteristic of the grass that the root system begins near the

surface of the soil, regardless of the depth at which the seed is placed. The best depth, everything considered, is about 1 inch, but where the soil does not become packed the plant will force itself to the surface even from a depth of 3^ to 4 inches.

In the semiarid regions for hay, and in any locality for seed pro- duction, better results are obtained by seeding in rows far enough apart to allow cultivation. This can be accomplished with a grain drill by stopping up a sufficient number of the holes so that the rows will be the desired distance apart. If only the ordinary corn culti-

vators are available for the work it is best to place the rows 36 to 42 inches apart. (Fig. 7.) If a beet cultivator or some similar tool is available, larger yields can be obtained from rows 18 to 24 inches apart. Twenty-four inches is perhaps as close as practicable, unless horses especially trained to walk between the rows are to be had. Otherwise much of the stand will be destroyed by trampling in rows less than 24 inches apart. Against any difference in favor of the cultivated-row planting over the broadcasted field will have to be charged the cost of cultivation. A better quality of hay is produced from the broadcast stand, owing to the finer stems. The grass grown in cultivated rows is likely to be coarse and therefore not so desirable for market hay. For home feeding the coarseness will be of little
