The numerous American native species are of considerable value on the ranges, many of them being eaten readily both by sheep and cattle. Some danger attends the feeding of this hay, to sheep, owing to the pres- ence of a poisonous alkaloid in the seed. [Consult Vol. III.] The cultivated lupines have been tested at many of the American experiment stations, mostly with decidedly unsatisfactory results. Only on the Pacific coast have the cultivated lupines appeared at all promising as green-manure crops, and even there other legumes are more satisfactory. Up to the present time, none of the species has become espe- cially valuable in the United States. It is not at all unlikely, however, when it shall become prof- itable to build up some of the sandy soils in the West, that one or more of the European species may prove valuable. One of the species, native to California (L. affinis), has been grown there as a green-manure crop and compares favorably with the European species. Culture. Soil.—A sandy, well-drained soil is essential, as the plants will not grow on wet land, and are par- ticularly averse to limestone soils. Their greatest value is on poor, sandy soils that will not grow anything else. On the other hand, it was found at the California station that lupines would tolerate much more lime on clay soils than on sandy soils. It is said that the large blue lupine (, var. ccendcus) and the pink lupine (L. pilosus, var. roseus) are adapted to limestone soils. Fertilizers.—Potash salts give the most benefici
