The above species is very abundant in Montana, where it is said to have caused the death of a very large number of sheep. There is some question whether the animals are killed by a poisonous constituent of the plant or merely by tympanites. The seeds of all the lupines are probably dele- terious in the raw state. In Europe, however, the seeds of Lupinus alius, after the bitter taste has been re- moved by steeping and boiling, are eaten by human beings as well as by cattle. POISONING BY LUPINES (lUPINUS LEUCOPHYLLUS ; L. SEPvICEUS ; L. CYANEUS). These plants are commonly known by the names blue pea, blue bean, and wild bean. They are coarse, silky-haired perennial herbs, with blue flowers arranged in conspicuous terminal racemes, which blossom in June and July, with long-stemmed leaves, which are divided into from seven to eleven leaflets radiating from a common point. The fruit is a hairy, several-seeded pod, and the seeds are small and somewhat flattened. As a rule these plants do not occur in the flat river bottoms. They occur most abundantly on the foothills and mountain ranges at moderate elevations. During the season of 1900 the lupines in Montana began to bloom about May 20th, and the first full pods were collected on June 5th. Lupines are not very extensively eaten by sheep during the spring and summer, except when they are unusually hungry or are being driven from one range to another. Lupines are more often eaten by sheep in summer on the mountain sides, and in the fall and early winter after R.
