flowctl Silver Creek, u tributary of the Weber. The average altitude of 

 this park is about 6,500 feet, while some of the neighboring peaks of the 

 main range rise 4,000 feet or more higher, and on whose bare, rocky sum- 

 mits spots of snow linger all the summer in the sheltered places. The 

 general character of this park is that of a luxuriant meadow, parts of it 

 under cultivation, the hill-sides being covered with a thick scrub of dwarf- 

 oaks (Qiiercus alba, var.?), while the higher slopes are covered by a dense 

 forest of Cofliferae, composed of several species (Pimis flexiUs, P. jionderosa, 

 P. contorta, Abies menziesii, A. englcmanni, A. donglassi, A. grandis, A. ama- 

 b'dis, and Jimiperus virginiana). The higher portions of the ravines are 

 occupied by shady groves of tall aspens {Popidiis tremtdoides), while bordering 

 the lower portions of the streams grow scattered trees of the narrow-leafed 

 cotton- wood (Popidus angusti folia), and luxuriant shrubbery, of varied species. 

 Indeed, the desert character of the country to the westward of the Great 

 Salt Lake was here almost entirely wanting. As a natural consequence of 

 increased prevalence and luxuriance of vegetation, the birds were much 

 more numerous than we had found them at any previous camp, and while 

 we found eastern trees and shrubs replacing their western representatives, 

 or added as new elements to the western sylva, we also found many birds 

 of the Eastern Region as common here as at any point in the Atlantic States. 

 Such species were the Cat-bird {Galeoscoptes carolincnsis) Swainson's Thrush 

 (Tiirdiis sivainsoni), Redstart (Setophaga ndidlla), and White-crowned Spar- 

 i-ow {Zonotrichia leucophrys). A species of the plains, or the Campestrian 

 Province {Calamospiza bicolor), Avas also here met with for the first time, 

 while several birds characteristic of the Rocky Mountains proper were 

 more or less common, as Turdus auduboni, Helniinthophaga virginice, PassereUa 

 schistacea, Junco caniceps, and Cyanura macroloplia. In this beautiful park 

 three species of Humming-birds were found, viz : Selasphoms platyccrcus, 

 Stcllula calliope, and Trochilns alexandri, the flowery meadows of the upper 

 portion of the canons being especially attractive to these "feathered 

 gems."
