and prevents them from making seed. If not thus clipped, they would frequently injure the crop more by shade and crowding than would a nurse crop. The mulch thus made through clipping back the plants is in many instances quite helpful to them, because of the check which it gives to the escape of ground moisture. There is some difference in the view held as to whether close clipping is preferable, but the balance of authority is in favor of reasonably close clipping. Alfalfa is usually sown alone, but in some instances it maybe advantageous to sow more or less of some other kind or kinds of grass or clover along with it. When grown for hay it is usually preferable to sow the seed without admixture. But there may be instances in which medium red or alsike clover may improve the crop the first year or two that it is mown for hay. But where red clover grows much more vigorously than alfalfa the first season, it should not be thus sown in any considerable quantities, or the clover plants will injure the alfalfa plants by crowding and overshading. Nevertheless, alfalfa may frequently with profit form a considerable factor in clover grown as pasture. Where the main purpose of sowing alfalfa is to provide pasture, various grasses and clovers may be sown along with it, and in varying quantities, according to the attendant conditions. The choice of the variety or varieties to sow along with the alfalfa should be based on the needs of the stock to be pastured, and on the degree of the vigor with which these grow and maintain themselves in the locality. In the Northern States and Eastern Canada timothy and Russian brome grass (_Bromus inermis_) may be chosen. In areas with Southern Illinois as a center, red top and timothy should be satisfactory. In the Southern States, the claims of orchard grass and tall oat grass would probably be paramount. In areas with Iowa as a center, nothing would be more suitable, probably, than Russian brome grass. In the mountain States, with Wyoming as a center, timothy and alsike clover would be suitable. In the dry upland country in Washington and Oregon, Russian brome grass or tall oat grass would answer the purpose. In many areas the plan of sowing clover chiefly with the alfalfa is a good one, providing the alfalfa is cut for a year or two, and is then grazed, as by that time grasses indigenous to the locality, or which grow well in the same, come in to such an extent as to form a very considerable proportion of the pasture. Blue grass frequently behaves thus in the North, and crab grass in the South.
