While yellow clover is not the equal of the small white clover in adaptation to our conditions, it would seem that there are no reasons why it should not be sown to a greater extent than it is sown under American conditions. A plant that is so hardy, that provides a considerable quantity of reasonably good pasture, that stores nitrogen in the soil, and that, moreover, does not stay in the soil to the extent of injuring crops that follow the breaking up of the pastures, should certainly be encouraged to grow. SAND LUCERNE Sand Lucerne (_Medicago media_), sometimes designated _Medicago falcata_, is probably simply a variety of the common alfalfa (_Medicago sativa_). Some botanists, however, look upon these as two distinct species. Others believe that _Medicago sativa_, with blossoms ranging from blue to violet purple, and _Medicago falcata_, with yellow blossoms, are two distinct species, while _Medicago media_, with blossoms ranging from bluish and purple to lemon yellow, is a hybrid between these. The name Sand Lucerne has doubtless been given to this plant because of the power which it has to grow in sandy soils. Sand lucerne is so nearly like common alfalfa in appearance and habits of growth, that until the blossoming season, careless observers cannot distinguish between the plants. (See page 114.) Sand lucerne, however, has a more spreading habit of growth than common alfalfa, the seed-pods are less coiled and the seeds are lighter. The root system is strong and the roots are probably more branched than those of ordinary alfalfa. Under Michigan experience, given in Bulletin No. 198 of the Michigan Experiment Station, it has shown considerably higher adaptation to light, sandy and gravelly soils than the former. The feeding properties of sand lucerne would not seem to be far different from those of common alfalfa (see page 119), but it is claimed that the former is considerably less liable to produce bloat in cattle and sheep than the latter. Sand lucerne is probably native to Europe and Asia. Some attention is given to growing it in Germany, the principal source from which comes supplies of seed at the present time. It was introduced into Michigan by the experiment station of that State in 1897, and its behavior in several trials made to grow it on sandy and gravelly soils in various places, has, on the whole, been encouraging. Since this variety, like the Turkestan, being considerably hardier than common alfalfa, can undoubtedly be grown further north than the latter, there would seem to be no reasons at the same time why sand lucerne would not grow satisfactorily on sandy soils that lie far south, but this does not seem as yet to have been proved by actual demonstration. It is possible, therefore, that this plant may render considerable service to areas scattered over considerable portions of the United States and Canada, in which the soil is light.
