DESORIFTION OF CAMPS. 365 



the Sharp-tailed Grouse {Ped'mcetes columhianm) was very abundant. The 

 principal species met with along this creek were, besides that above-named, 

 the following: — 



Turdus guttatus One specimen. 



Tarus septeutrioualis Rare. 



Zonotricbia intermedia Abundant. 



Juueo oregouus Abundant 



Passerculus alaudinus Abundant. 



Empidonax obscurus Common. 



Sphyrapicus nuclialis Bare. 



Pious harrisi Rare. 



Melo.spiza fallax Abundant. Picus gairdneri Rare. 



Melospiza liucolui Abundant. \ Autrostouius uiittali . Common. 



Pipilo cliloi urus Common. 1 



81. Clover Mountains (September 19, 1868). — On the above date, a 

 trip was made to near the summit of the main peak of this range by follow- 

 ing Trout Creek from our camp up the canon to its head, returning by 

 another canon to the southward. The summit of this peak is very lofty, 

 rising considerably above the timber-line, or to an altitude of near 12,000 

 feet. Large fields of perpetual snow lay in the ravines and behind masses 

 of rock, and in several places below the bare summit were quite extensive 

 pine woods. Nothing of interest, ornithologically, resulted from this exceed- 

 ingly laborious day's work, however, only the usual species being observed. 

 The commoner species of the alpine woods were Sitta canadensis, Parns 

 montamis, and Junco oregonus, while at the head of one of the cations, where 

 pines and aspens were intermingled, Canace obscura was very abundant. 



32. Holmcs\s Creek, near Thousand Spring Valley (September 22-26. 

 Altitude, about Q, 000 feet). — Observations at this camp were confined chiefly 

 to a small valley nestled among a range of low hills separating the valley 

 of the upper Humboldt from Thousand Spring Valley. Around a spring, 

 which supplied the camp with water, grew a thicket of tall willows and 

 aspens, while along the rivulet from this spring grew willow bushes. Else- 

 where, only the ordinary sage-brush plants flourished. In the thickets 

 above mentioned, Bendrosea townsendi, Sphyrapicus nuchalis, and Nyctale 

 acadica were obtained. 



33. ''City of Rocks,'' "^ Southern Idaho (October 2, 1868).— The hills 



'This locality derives its name from a remarkable valley among the mountains 

 close by, where immense piles of granite, rising from the floor of the valley, vaguely rep- 

 resent a city of castles, domes, and mosques.
