REPORT OF AN INVESTIGATION OF THE GRASSES OF THE ARID 

 DISTRICTS OF NEW MEXICO, ARIZONA, NEVADA, AND UTAH. 



Eaton, K"ew Mexico, June 6. 



Eaton is at the southern base of tlie Eaton Mountains. The adjoin- 

 ing plains afford excellent pasturage, being well covered with BucMoe 

 dactyloides (Buffalo grass) and Hilaria Jamesii, while in many places 

 Agropyrum glaucum is becoming very abundant, and is said to be in- 

 creasing annually and valued very highly. The latter is occasionally 

 cut for hay, and is everywhere known as " Blue-grass." The higher 

 mesa lands also give good pasturage and are often cut for hay. Agro- 

 pyrum repens (Quack grass), a species of Poa (P. Tracyi), a variety of 

 Festuca ovina, and a species of Garex, apparently muricata, are very 

 abundant, and there is a considerable mixture of Boutcloua oUgostachya 

 (Grama-grass). 



Eain-fall is said to be on the increase. Alfalfa and oats form the 

 leading cultivated hay crops. 



The following notes were taken on the grasses found here : 

 Koeleria cristata. 



Occasionally seen on the sidesof the mountains, and on the mesas. 

 Found at almost every station on the whole trip, but never 

 very abundant. It is known as June grass. 



Festuca ovina, var. 



Very abundant at the top of the mesa, but not yet in flower. It 

 forms a large part of the mesa hay. 

 Bouteloua oUgostachya (Grama-grass). 



One of the most common species on the mesas. 

 Agropyrum glaucum (Blue-joint, Blue-grass). 



Common on lowlands and the sides of the mesa. 

 Hilaria, Jamesii (Black bunch-grass). 



Very abundant on the vegas (meadows) with Buchloc, and said 

 to be increasing. It makes excellent pasture at all times when 

 not covered with snow. 

 Poa pratensis (June-grass, Kentucky blue-grass). 



Seen at one place on the side of the mountains only.
