grass here seemed to be a form of Festuca ovina L. In the canyons 
several species of Poa are common, and afford valuable grazing. 
t Red Rock the valley is narrower and somewhat drier, there 
being no high mountains in the vicinity to furnish moisture as at Lima. 
Only along the creek was there a good growth of 
grass, Near the station there was a fine meadow, 
the principal grass of which was a Blue-grass 
(Poa species), valuable for hay and pasturage. 
At Dillon a much larger portion of the valley 
was under cultivation and irrigation, and some 
fine meadows of native and cultivated grasses 
were to be seen. Among the native species were 
Elymus wios Nutt., Stipa comata Trin. & 
Rupr., Spartina gracilis qu. 4 Agropyron que 
dorepens S. & S., Phalaris arundinacea L., 
Calamagrostis neglecta Giertn. 
BIG HOLE VALLEY. 
The widest part of this valley, 
at least along the railroad, is at 
Melrose, where we were July 5-8 
and August 1. On both sides of 
the river and along its tributaries 
we found good meadows. 
The chief grasses were Poa pra- 
tensis L., Poa nevadensis Vasey, 
Agrostis alba L., Koeleria cristata 
Pers., and Calamagrostis neglecta 
Gertn. In the drier parts of the valley we also found 
Bouteloua oligostachya Torr. rather common. The hills 
were quite barren, scattered specimens of Agropyron 
divergens Nees, Eriocoma cuspidata Nutt. and Stipa 
comata Trin. & Rupr. being most common.

DEER LODGE VALLEY. 
Near Silver Bow the valley is dry and barren, but 
toward the hills to the west, there were some meadows 
watered by mountain brooks. The principal grasses, " 
which made quite an amount of hay in places, were Fic.3.—Slough-grass 
Deschampsia cespitosa Beauv., Festuca scabrella Torr,  Bermannia erw 
Festuca rubra L., and Koeleria cristata Pers. T 
Farther Joib the valley widens, so that at Anaconda itis several 
miles wide. From here to Deer Lodge it is well under eultivation and 
fine farms occur all along the road. At Deer Lodge there are good 
meadow lands, the chief grasses being Festuea rubra L., Poa buckley- 
ana Nash., Poa pratensis L., Agropyron spicatum 8. & 8. Beckmannia 
erucajormis Host. (tig. 3), Bromus breviaristatus Ar o dies
