are ready to offer a handsome reward to any one- who will free 

 their lands from this species. It has strong, underground stems, 

 which grow deeply, taking the soil completely. This habit 

 makes Johnson-grass exceedingly difficult to eradicate, for the 

 least fragment of these underground stems, if left in the soil, 

 serve to produce a new plant. Unless we wish to give the land 

 up forever to this grass, we should not think of cultivating it. 



Andropogon Virginicus, Linii. — Broom Sedge, Broom-grass, Vir- 

 ginia Beard-grass, Sedge-grass. 



There is probably no native grass better known 

 to our farmers than this, and, although when 

 quite young it affords excellent grazing, it is, 

 on the whole, one of our worst weeds, rendering 

 the formation of permanent meadows almost 

 impossible. Constant tillage seems to be our 

 only means of keeping this grass from occupy- 

 ing our land. 

 Annual Meadow-grass — Poa annua.

Antlioxanihum odo 



ratum. 



Vernal-grass. 



A low, slender perennial with a close, narrow 

 "head." This grass has been introduced from Eu- 

 rope, and is valued on account of its earliness 

 and sweet odor when dry. It can only be recommended in mix- 

 tures for pasture. 

 Arabian Millet, or Arabian Evergreen Millet. — Sorghuin Halapense. 



Aristida dichotoma, J//V/^;ic:.— Poverty-grass. 



A low and much branched annual, common in dry, sterile 

 soil, or open fields. Wholly worthless. 



Aristida purpurascens, Poir. — Beard-grass. 



Allied to the last and growing in similar situations, but taller 

 and much less branched. Of no value. 



Arrhenatherum avenaceum, Beauv. — Tall Oat-grass, False Oat- 

 grass, Tall Meadow-Oat-grass, Evergreen-grass, Oat-grass, 

 Grass-of-the-Andes, French Rye-grass. 

 A highly valued grass, both for winter grazing and for hay. 

 It has been introduced into this country from Europe, where 

 it is regarded as one of the best fodder grasses. As it stands in 

 rather loose tufts, it is best to mix the seed with those of other 

 grasses in order to thicken the sward. It grows rapidly, blooms 

 early, and when cut, dries out readily, and when dry, keeps 

 well. It is not regarded as a suitable grass for moist soils.
