The best preventive is to not allow the cattle to become too hungry. We get, on an average, three cuttings a year, averaging 1 to 1¹⁄₂ tons per acre each, and have pasture for five or six months. For hay, we mow when in full bloom, rake as soon as possible, and let stand in windrows until the stems are about half dry; then put in the cock for two days, and stack in large ricks of about 80 to 100 tons each. If put up damp or green, it will mold. The seed is harvested, usually, from the second crop, when the pods turn black and can be shelled out by rubbing in the hand. It is cut, raked in windrows, and allowed to stand until thoroughly dry. I used, this season, a J. I. Case separator, and threshed and cleaned 6000 pounds of seed in three days. An ordinary yield is 100 pounds to the acre, and the cost of cutting and threshing is 3 cents a pound. The total cost of the hay in the stack is about $3 a ton on $50 land, with 15 cents an acre for irrigation. The average selling price for hay is $4 a ton, and for seed, 10 cents a pound. With proper care, alfalfa will last time without end, and improve each year, and it is difficult to kill it out, as it makes more or less seed every crop. An open soil, free from hardpan, is best for it. CALIFORNIA _Henry Miller, San Mateo county._--Since 1871, we have gradually increased our acreage of alfalfa, until we now have about 20,000 acres. This is on reclaimed swamp and upland, under a complete system of irrigation, with the exception of a little light, loamy soil, with water near the surface and no irrigation. On the latter ground the plant is short-lived, on account of the gophers. The depth at which well water is found varies from 10 to 40 feet, and, with irrigation, it is immaterial whether the soil is naturally moist or dry. The preparation for seeding consists of deep plowing and cross plowing, and the depth for planting is not over two or three inches. For light, loamy soils, 12 pounds of seed to the acre is ample, while for hard, rough, new land, from 16 to 20 pounds is required to insure a good stand. Seeding may be done here after the cold season, and when danger of heavy frost is past, but in time to take advantage of the spring rains, which are very essential. During the first season, the weeds should be mowed as they require it, without regard to returns of alfalfa, and after they are subdued it is well to let the first year’s growth go to seed and allow it to be trampled into the soil by young stock, but if there is a full stand this is not necessary. We irrigate from streams, applying water as soon as the spring opens and every time a crop is cut, the quantity of water needed depending on the quality of the soil. Drainage is very necessary, especially when irrigation is done in warm weather. After the first irrigation, less water is needed at an application than at first. Winterkilling seems to be effectually prevented by watering in the fall.
