5. Big-Bend of the Truchee {altitude, 3,995 /cf^- July 24-Auo-ust 18.)— 

 After emerging from its deep,narrow gorge through the Virginia Mountains, 

 the Truckee River bends abruptly to the left, and flows toward the north- 

 west into Pyramid Lake, about thirty miles distant. The vicinity of our 

 camp at this place proved a rich locality for birds, for the naiTOw valley 

 of the river was very fertile, supporting a rich and varied vegetation, while 

 the arid sage-brush plain stretched off on one side to the Humboldt Desert, 

 and in the opposite direction to the Virginia ]\Ionntains. Only the very 

 few birds characteristic of the desert could exist upon the surrounding 

 sandy wastes, and, as a consequence, the fertile valley was rich in the 

 number of species and individuals crowded within the narrow limits 

 embraced between the steep earth-walls. Along the bank of the river, and 

 surrounding the sloughs connected with tlie stream, ^vere exceedingly 

 dense willow -Jungles, tlie sloughs tliemselves being filled with rushes, 

 flags, and other acpuitic plants; but most of the valley consisted of 

 meadow-land, interspersed with velvety swards of "salt-grass" and acres 

 of beautiful sun-flowers (Ilclianthus giganteus), studded with tine large 

 cotton-wood ti-ees {Popuhts monilifera and P. trichocarpa), which were here 

 and there grouped into delightful groves, sometimes unincumbered, but 

 generally with a shrubby undergrowth, amongst which the "buffalo-berry" 

 {Shepherdia nrgentea) was conspicuous. No birds, excepting Mourning Doves 



' A single specimen of wbat was probably this species was observed, flying over, 

 on the 19th of November.
