The latter is a prairie grass which is excel- lent for pasture but may be classed as a weed when found in grain fields. Careless broaking and neglect of the headliinds is largely responsible for its appearance in cultivatpd lands. The treatment recommended for the eradi- jation of these grasses is shallow ploughing during hot, drj- weather, folIowe<l by frequent cultivation. BARLEY GRASS—Hordeum juhatum. L. Also called squirrel-tail, skunk- tail, wild barley and fox tail. This well known native grass which is rather a weed of the hay- field than of the p-ain crop is a source of much injury to horses, cat- tle and sheep. Tho boarded heads when taken into the mouth break up, adhere to and penetrate tho mucous inembrane. They also work in be- tween tho teeth and under the ton- gue causing inflammation and ulcers which eventually affect the jaw bones. It grows most abundantly on alkaline soils whore the conditions nre not so favourable for the growth of better grasses. There is no diffi- , . , culty in eradicating it from anv land which can be ploughed, as the usual method of breaking in .Tune will destroy it. It gives most trouble, however, by growing on waste places where it ripens its seed, which is spread abroad by wind and water It grows freely about the edges of hay sloughs on'the prairie and is generally ripe before any hay is cut. The remedy in this case would be cutting before the seeds are formed. In a wet season, probably a second cutting wonld he necessary to prevent any seed ripeni
