WHEAT RESEARCH
POISON" FOUND TN TARES. (By Telegraph—Per Press Association.) CHRISTCHURCH, Nov. 19. 'Flie presence of prussic ackl in tares has been discovered accidentally hv Mr R". E. West, chemist of the Wheat Research Institute. The tares, when dry, give off no odour, but when wetted ,or when coming in contact with moisture in an animal’s mouth or digestive organs, they smell ’ strongly of butter almonds. Mr West has proved that this smell actually comes from hvdro-cyanic acid gas, is volatile, and is given off in baking, so that no harm <■oll come from the consumption of bread baked from flour that is milled from wheat containing tares, but the offals of such flour, if fed to stock, would be harmful. Mr West hopes that bis experiments may he valuable in the production of better stock food. Tests in feeding will be carried out. The discovery was made accidentally. Mr West noted a peculiar odour from a test tube containing tares, and the gas causng the odour was tested, and it proved to be prussic acid.
