tudes, as it does not reach a maximum growth for several years after the seed has been sown. But in mild latitudes, it may be found practicable to introduce it into short rotations, like other alfalfa (see page 135), and on land that is too sandy to grow the common variety in the best form.

Much of what has been said about the preparation of the soil for common alfalfa will equally apply to the preparation of the same for sand lucerne. (See page 137.) But when the latter is sown on sandy or gravelly land, a moist condition of the seed-bed at the time of sowing is even more important than when sowing common alfalfa under ordinary conditions.

The same methods of sowing the seed will be in order as are suitable for sowing common alfalfa in any particular locality. (See page 147.) This will mean that in Northern areas sand lucerne can best be sown in the spring and as early as the danger from frost is over, that the plants may get as much benefit as possible from the moisture in the soil before dry weather begins. It will also mean that if sown southward in the autumn, it may in some instances be necessary to wait longer for the sandy soils on which the seed is sown to become sufficiently moist to sprout the seed than for such a condition. in soils on which common alfalfa is usually sown. The amounts of seed to sow will also be practically the same. (See page 152.)

The adaptation of sand lucerne for providing pasture is as high, if not, indeed, higher, than that of common alfalfa, since it is said that it has less.

tendency to produce bloat in cattle and sheep, and it is not so easily destroyed, at least in Northern areas, by grazing. In providing pasture, its higher adaptation is in furnishing the same for cattle, swine and horses.

With ample moisture, even as far north as Lansing, Michigan, three crops of hay may ordinarily be looked for. At the Michigan Experiment Station, sand lucerne sown in 1897 yielded cured: In 1898, at the rate of 6800 pounds per acre; in 1899, 10,580 pounds; in 1900, 12,310 pounds; and in 1901, 13,839 pounds. The methods of cutting and curing are the same as for other varieties of alfalfa. (See page 170.) The quality of the hay is not far different from that of common alfalfa. If there is a difference, it would, perhaps, be a little against the sand lucerne, owing to the nature of the land producing it. For soiling food, it may be handled in the same way as common alfalfa. (See page 166.)

No further information would seem to be available with reference to the production of seed in the United States than the statement that the efforts to grow it in Michigan had not been altogether successful. The question thus raised has an important bearing on the future growth of the plant, as, if seed is to be imported from Europe when sand lucerne is to be sown, the expense of securing seed is likely to militate against extending its growth. It is probable, however, that this difficulty will be overcome through the more perfect acclimation of the plants in the North, or by growing seed from the

same in Western areas which have shown higher adaptation to the production of alfalfa seed.

The value of sand lucerne in fertilizing sandy and gravelly soils in this country may yet be very considerable. Its value in putting humus into the same may prove equally high. This value will arise chiefly from its greater ability to grow on such soils than various other legumes. When sown primarily for such a use, heavy seeding would seem to be preferable to ordinary seeding.

JAPANESE CLOVER

The United States Department of Agriculture has quite recently introduced a variety of clover known botanically as Lespedeza bicolor. In 1902 small lots of seed were distributed to ascertain the value of the plant grown under American conditions. Sufficient time has not yet elapsed to prove its value, but the indications encourage the belief that it will be of some agricultural value under certain conditions.

This variety of clover is more erect and less branched in its habit of growth than the Japanese variety Lespedeza striata. Under Michigan conditions it was found to grow to the height of 3 feet on sandy soil and to about half that height on clay soil, the seed having been sown about the middle of May. The stalks are about the same in structure as those of alfalfa, and like alfalfa they do not lodge readily. The leaves are ovate in form and of a peagreen tint. The seed is formed in pods resembling those of lentils, only smaller. The seeds are larger

than those of crimson clover and are oblong in shape. In color they are mottled brown, yellow and green. The roots in the Michigan test produced nodules freely and without inoculating the soil by any artificial means. The plants in the same tests were killed to the ground by early October frosts.

This variety, like that grown so freely in the Southern States, is an annual. In the absence of experience in growing it under varied conditions, it would be premature to dwell upon its value. If it should grow readily on sandy land, as the Michigan test would seem to indicate, it would render substantial service in fertilizing such soils. In the grass garden of the Department of Agriculture at Washington, D. C., its behavior has been such as to encourage making further tests.

FLORIDA CLOVER

Florida clover (Desmodium tortuosum) is sometimes grown both for hay and pasture, more especially in the Gulf States. It has been designated botanically Desmodium molle, and is also known by the common names Beggar Weed, Giant Beggar Weed, Beggar Ticks and Tickweed. The name Florida Clover has been given to it because of its prevalence on the light soils of Florida. The name "beggar" has probably been applied to this plant because of its relation to poverty in soils, in which it is more commonly grown, and the name "ticks" from the clinging habit of the seed-pods to surfaces with which they come in contact.

Beggar Weed is an erect and branching plant,
