ECONOMIC AND ORNAMENTAL GRASSES. 
Agropyron caninum R. & S. Bearded Wheat-grass; Awned Wheat-grass; Fibrous- 
rooted Wheat-grass. 
A 1 cr slender, upright grass, 2 to 3 feet high, with bearded nod- 
r spikes resembling slender heads of wheat. This grass is more 
or less iiic in the northern parts of the United States, ranging from Maine 
to South Dakota. Bearded Wheat-grass is closely related to the more common 
and better known Couch-grass ( 4. repens), but differs markedly from that spe- 
eies in having no creeping rootstocks, and in the longer beards or awns to the 
spikelets. No attempts have been made to introduce this grass into general cul- 
tivation, bat its Dabi; of growth asd 8 character indicate that it may

Azropyron divergens Nees. Wire Bunch-grass; Apache Blue-grass (New Mexico); 
Wiry Wheat-grass 
A slender, usually N tufted grass, 1 to 2 feet high or more, with very narrow, 
spreading leaves, and bearded or beardless spikes. The beards or awns, when 
present, are widely spreading or divergent. This grass is common in the Rocky 
Mountain and Pacific Slope regions, extending westward to the coast. On rich 
lands it often grows to the height of 3 feet, but npon the dry bench rte it 
rarely exceeds a foot or 18 inches in height. On dry lands the stems ome 
wiry with age, and are avoided by stock; but the grass is considered validi 
by the ranchmen for winter grazing. Samples of this grass receiv some 
points in the West, particularly from Washington, indicate that it possesses 
much agricultural value when grown upon good soil, and as it will thrive in 
the semiarid regions of the 8 its cultivation may prove desirable. 
Propagated readily by seed, which ean be easily gathered.

A grass abundant every where in the Eastern and Middle States, growing in the open 
fields, and in many places it has become one of the worst o Often the 
chief labor in managing hoed crops consists in subduing this pest. When once 
established, it is hardly less difficult to eradicate than the well-known Johnson- 
grass of the Southern States. It is, however, a valuable hay grass, and for two 
or three years the yield is large, but, like the Western Blue-stem, it “binds 
itself out," and the sod requires breaking in order to restore the yield. It is
