Short-leafed Eatonia ( Eatonia nitida). 
r Found occasionally in the eastern part of North Dakota. The forage is of good 
f quality, but the grass is too rare to be of much importance. 
Sisyrinchium angustifolium. (See Blue-eyed grass.) 
Slender Beak-rush (Rhynchospora capillacea). 
Rare and too small to be of any importance as a forage plant. 
T Slender Cord-grass (Spartina gracilis). 
E Much like the common Cord-grass, but smaller and of less importance agriculturally. 
E It occurs in moist saline soils, and, to a certain extent, replaces the larger species 
in the western part of the Dakotas. 
Slender Fescue (Festuca octoflora). 
d A slender annual found on dry, rocky knolls. It adds more or 
importance agriculturally. Its chief value lies in the fact 
that it thrives on soils upon which few other grasses will 
grow. 
Slender Wheat-grass (Agropyron tenerum). 
This is one of the best of the wheat-grasses. It is not so aggres- 
sive as some of the other species, as it does not spread b 
receive more attention from farmers and stockraisers. (See 
Slough-grass ( Beckmannia eruceformis). 
Abundant in sloughs and wet places. While young itis much 
relished by stock, and often forms a considerable amount of 
t UE 
important grass in localities where better species can not be 
grown (fig. 8). 
Small Panic-grass (Panicum scribnerianum). 
Not uncommon in rather dry upland meadows, furnishing a small amount of nutri- 
tious forage. 
Smooth Brome-grass ( Bromus inermis). 
An introduced species, which is rapidly becoming one of the most important forage 
plants of this region. Its hardiness, heavy yield of both forage and seed, 
and m ease with which a good stand can be egt make it a very desirable 
r permanent meadows and pastures. It is not a good grass to use in 
Short Ein as the very characters which render ite so hardy and so desirable 
for permanent fields enable it to persist in the soil, and hence it may become a 
weed under such conditions. 
Sorghum ( 4ndropogon sorghum vars.). 
The saccharine sorghums are often cultivated for the manufacture of molasses and 
also for forage. For the latter purpose they are usually sown broadcast or in
