inch long, and from one-eighth to one-quarter of an inch wide, 
standing at right angles like a small flag floating in the breeze. 
Where — grazing prevails, however, these flowering stalks 
are eaten down so much that only the mats of leaves are

more closely, and under favourable circumstances forms a pretty

is sometimes cut, making a very light erop. Under the most 
favourable cireumstances the product of this grass is small, 
compared with cultivated grasses. It is page etree highly 
nutritious. Stock of all kinds are fond of it, and eat it in 
preference to any grass growing with it. It "ane s and cures on 
the ground so as to retain its nutritive picperios in the winter. 
No attempt is made by stockmen to feed cattle in the winter ; 
they are expected to “rustle around,” as the phrase is, and find 
their living ; and in ordinary winters, as the fall of snow is light, 
they are enabled to subsist and make a pretty good appearance in 
the spring ; bnt in severe winters there are losses of cattle, some- 
times very heavy ones, from want of feed.
