The downy brome-grass or slender chess (B. tectoruM L.) oc- curs in the northern part of the State, and is liable to become a bad weed. It may be known by its weak stem and somewhat one- sided downy panicles. The lower empty scale is but 1-nerved whereas in cheat it is 3-nerved. Remedies the same. 9. Agropykon bepens L. Couch-grass.

Stems several, 1-3 feet tall, from a long jointed running rootstock; sheaths smooth; leaves flat, rough above. • Spike 2-8 inches long, not branched; spikelets in 2 rows, 3-7 flowered, the scales glabrous, acute or short-awned. Seeds slender, i inch long, 5-7 nerved and short-awned at tip. (Kg. 24.) A perennial grass, sometimes cut for hay but in most places a vicious weed, occurring in grain fields, spreading by its large, strong creeping rootstocks and crowding out the grain. June- Sept. T-he rootstocks run just be- neath the surface and are so strong and unyielding that they have been known to push their way through a Remedies: (a) in culti- vated fields, shallow plowing in early autumn, then harrowing to work the rootstocks free from the soil, followed by raking and burn- ing, or if too wet, throwing them into heaps and allowing them to rot. A second and deeper plowing, har- rowing and raking will often be necessary to thoroughly remove the deeper growing stocks. Such fall plowing, followed by thorough cul- tivation the next season, will usually clean out the weed, (b) Shallow plowing and harrowing in hot dry weather, (c) Plowing under. Fig.
