. Weeds of the farm and ranch [microform]. Sols; Weeds; Tillage; Mauvaises herbes. •• Dkfastmxitt ov CORN COCKLE-Agrottemma QUhago, L. CoBW AWD Cow Cockle.—Those two plants are not native*, but are becoming rapidly abundant in the grain fields as troublesome weeds, and their seeds have formed the principal part of the screenings at some points in Saskatchewan re- cently. The seeds of the first men- tioned are extremely difficult to i»ep- ! arate from wheat. The pois-«nou8 constituent in each is saponin, the action of which is antagonised bv the extract of digitalis, a powerful poison. The most dangerous part of cockle is the seed, and care should be exercised that it may be removed from wheat before milling, and from food for stock. Chronic poisoning may be induced, resulting in diar- rhoea and gradual depression, with death. Acuic poisoning is indicated by vomiting, headache, nausea, ver- tigo, diarrhopa, hot skin, pains in back, difficult locomotion and de- pressed breathing. Coma is some- times present and is followed by death.* "^ FLAX—Linum sp. Lakge-Flowerk,, Yellow Flax grows on our prairies, although not conspicuous. It has been experimented with in the States and proved poisonous to sheep. Blue Flax (L. usttat{ssimum)—In Europe the cultivated flax has caused poisoning sometimes in the pig, cow, sheep, and in poultry'; this IS due to acrid narcotic poison (linine) contained in the sep^^ D«..rtm«nt of iUricul'tur.
