two easteru grasses, Oryzopsis juncea and 0. asperifolia. Near the 

 railroad occurred two forms of Poa n evade ns is, and Bromus pumpilHa- 

 nus, both of u more western range. On a wooded hill, together with 

 the tliree common Stipas, S. spartea, S. comata, and 8. viridula, grew a 

 fourth, iS. rich<(r(lsonii, of a more western range, and also DantJionia 

 spicata, from the East. 



But the most peculiar feature of this region is the damp atmosphere. 

 The Harney Eange differs in that respect from the Northern Hills. On 

 account of this dampness, and difterently from mountain regions in 

 general, the Harney Eange abounds in lichens, liverworts, mosses, and 

 ferns, es])ecially on the north side of the crags, where the rocks in many 

 places are literally covered by lichens and the base and crevices lined 

 by mosses and ferns. Tlie lichens and mosses were collected only inci- 

 dentally, but a good collection of ferns was made. My list contains the 

 following from this region:

LIiMESTONK DISTRICT. 



The Limestone District is a high table-land, running from south to 

 north, on the Wyoming line. It is separated from the Harney Eange 

 and tlie otlier hills by a valley. This table-land is the watershed of the 

 Black Hills, giving rise to Spearlish, Eapid, French, and Eed Canyon 

 creeks on the east side, and Eed Water, Inyankara, and Beaver creeks 

 on the west side. The ]»lateau is 1,800 to 2,000 meters high, the highest 

 point, Crooks Tower, being, next to Harney Peak, the highest in the 

 hills. The surface is made up of pine-covered ridges running north and 

 south. The valleys between these ridges are composed of excellent 

 hay land. The region resembles much some parts of Sweden. The 

 l)ine-covere(l hills were here, so also the meadows with the knee-deep 

 grass, and the flowers were in greater profusion and greater variety of 

 color than 1 have seen elsewhere in America. The Swedish species 

 were seldom present, but they had their counteri)arts: Hieracium, 

 Scofzonera, iiudMypocIi<jeris were matched hy Rudheelda liirtu, Gaillardia 

 aristata, and HeUanthus maximiliani; Lathyrns and yicia by Jjupinus 

 parrijhrns and /.. .scriveus; Geranium .sylvatieKm by Geranium riehard- 

 sonii; Chrysanthemum leucanthcmum by Aster ptarmicoides; and Sol- 

 idago virgaurea by ^olidago missouriensis. In the border of the woods 

 the same ohl Epilohium angnstifolium ])resented itself. 



The only trees seen in the district were the pine and the quaking 

 aspen.
