eastward from the ' Continental Divide' and extending north and 

 south over the breadth of Montana Territory/' gives the list of the 

 more important species, '* such as give character and value to the 

 region for grazing purposes," and the Buffalo Grass is not one of 

 them; it was not seen by him. As a noteworthy constituent of 

 grazing ranges, we may therefore exclude it from Dakota and 

 Montana. 



In Nebraska, which seems to be, or to have been, one of its 

 most congenial habitats, it is still common in the central and 

 southeastern regions, but quite rare in the northern and north- 

 eastern parts of the State. Prof. Bessey, in his instructive paper 

 on the ^'Grasses and Forage Plants of Nebraska," says : '* This re- 

 markable grass is disappearing rapidly from the State, and while 

 it may endure in small isolated patches here and there for perhaps 

 many years, it will ere long cease to have any agricultural

interest. 



In Kansas, according to the Agricultural Report of 1870 

 (p. 222), the Buffalo Grass reaches its eastern limits about lOO 

 miles west of Fort Scott, appearing there in small patches at the 

 base of bluffs. It is still common in the western part of the State. 



The authors of the " Flora of Colorado " give the single hab- 

 itat, '' Plains around Denver," which makes it probable that this 

 plant is common in the eastern prairie regions of Colorado, although 

 Dr. Rothrock, in the '* Botany of the Surveys West of the looth 

 Meridian" (p. 32), does not mention it among the "Bunch Grasses 

 of that State. 



It extends to southeastern Wyoming, having been recorded 

 as entering into the composition of the sod of the prairie around 

 Cheyenne. That it is quite rare, if not absent, from the northern 

 and mountainous western parts of this territory is sufficiently 

 obvious from the fact that it does not appear in the *' Flora of 

 the National Park." 



In Texas, according to my own extended observations in that 

 State, the Buffalo Grass is a not inconsiderable element of the 

 grazing ranges of the central and northeastern regions, extending 

 westward to the branches of the Concho River. It does not 

 thrive on the dry, sandy plains of the southwest and is rare beyond 

 the Pecos. I have failed to find it on the southern Staked Plains,
