flowed Silver Creek, a tributary of the Weber. The averag'e altitude of 

 this park is about G,5()0 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 nil 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 (Quercus alba, var.?), wliile the higher slopes are covered by a dense 

 forest of Conifera;, composed of several species {Pinus flcxilis, P. pondcrosa, 

 P. contorta, Abies menzicsii, A. enykmanui, A. douglassi, A. grandls, A. ama- 

 bilis, and Jnniperus viryiniana). The higher portions of the ravines are 

 occupied by shady groves of tall as})ens {Populiis trcmidoidcs), while bordering 

 the lower portions of the streams grow scattered trees of the naiTow-leaf(^d 

 cotton-wood {Populus 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 vegetfvtion, the l)irds were much 

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

 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 {Galcoscoptes caroUnensis) Swainson's Thrush 

 (Turdus swainsoni), Redstart {Sctophaya ruticilla), and White-crowned Spar- 

 row (Zonotrichia leucophrys). A species of the plains, or the Campestrian 

 Province {Calamospiza bicolor), was 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, Hdminthophaya viryinice, Passerclla 

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

 three species of Humming-birds were found, viz : Sdaspliorus platyccrcits, 

 Stcllida calliope, and Trochilus alcxumlri, the flowery meadows of the ujiper 

 portion of the canons being especially attractive to these "feathered 

 gems."
