very similar to that about Coolidge, but more sandy and barren. The 

 nearest ranch where good water can be had is 25 miles to the south- 

 east, and there are no others besides that within 50 miles. On the 

 sandy plains about here is a scant growth of Bouteloua oligostdchya 

 (Grama-grass), with a smaller amount of Buchloe dactyloides (Buffalo- 

 grass), the whole insufficient to afford range now (June 23), even if water 

 could be had. Along the river, which is strongly alkaline, DisticMis 

 maritima (Salt-grass), is almost the only species, and is eaten somewhat. 

 After frost, stock live mostly upon White sage (Atriplex), and "saleratus 

 weed " (Salicomia herbacea), which grows quite abundantly on soils too 

 alkaline for other plants. This plant is quite abundant about Salt Lake 

 City, the only other locality where it was observed on the trip, and is 

 valued highly there for winter feed. 



In the San Francisco Mountains, 50 to 70 miles southwest of here, 

 Black bunch-grass (Hilaria Jamesii) is very abundant, and regarded as 

 the most valuable species. Bouteloua oligostachya (Grama-grass) is also 

 common there, and in the pine woods "Pine bunch-grass'' (Festuca, 

 an undetermined species) is the main reliance for winter range. Wild 

 peas (Yicial) grow abundantly, and are very highly prized for sheep. 



Flagstaff, Arizona, June 24. 



Flagstaff is in the dense pine forests of the San Francisco Mountains, 

 at an elevation of 6,886 feet. Excellent grasses are abundant, but 

 owing to the total absence of living streams very little stock is kept. 

 The more common grasses are a Pine bunch-grass" (Festuca — — -), 

 Bouteloua oligostachya, Andropogon scoparius, and Agropyrum glaucum. 

 The latter is often cut for hay, but is not valued as highly for that pur- 

 pose as is the Bouteloua oligostachya. 



The following notes were token on the grasses found here :• 



Poa Californica. 



Somewhat common on the hill-sides. 



Stipa avenacea, var. 



Occasionally seen on the hill-sides. 



Stipa Pringlei. 



Common at the edge of the lava bed. 



Agropyrum glaucum (Blue joint, blue-grass). 



Very common, and sometimes cut for hay, but not valued highly. 

 Stock do not eat it when other grasses can be had, but it be- 

 comes an important item of feed when other grasses are cov- 

 ered with snow. 



Koeleria cristata. 

 Common.
