REPORT OF AN INVESTIGATION OF THE GRASSES OF THE ARID 
DISTRICTS OF NEW MEXICO, ARIZONA, NEVADA, AND UTAH. 
Raton, New Mexico, June 6. 
Raton is at the southern base of the Raton Mountains. The adjoin- 
ing plains afford excellent pasturage, being well covered with Buenloe 
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 forhay. Agro- 
pyrum repens (Quack grass), a species of Poa (P. Tracyi), a variety of 
Festuca ovina, and a species of Carer, apparently muricata, are very 
abundant, and there is a considerable mixture of Bouteloua oligostachya 
(Grama-grass). 
Rain-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. 
ccasionally 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 notyet in flower. It 
forms a large part of the mesa hay. 
Bouteloua pe peters te (Grama-gra 
One of the most common species on the mesas. 
Agropyrum hicks (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 Buchloe, and said 
to be increasing. It makes excellent pasture at all times when 
not covered with snow. 
Poa pratensis (June-grass, Kentucky blue-grass). 
een at one place on the side of the mountains only.
