h. Biff-Bend of the TnicJcee (altitude, 3,9dr)feet; July 24-August 18.) — 

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

 the Truckee River bends abniptly 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 nairow valley 

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

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

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

 few birds characteristic of the desei't could e.xist npon 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 eartli-walls. Along the bank of the river, and 

 surrounding the sloughs connected \\ith the stream, were e.xceedingly 

 dense willow -jungles, the sloughs themselves being filled with rushes, 

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

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

 of beautiful sun-flowers (Ilrliantlius ffifjantcus), studded with tine lai'ge 

 cotton- wood trees {Popidus monUifera and P. trichocarpa), which were here 

 and thei'e grouped into delightful groves, sometimes unincumbered, but 

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

 [Shcpherdia rrn/entea) was conspicuous. No birds, excepting IMourning Doves 



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

 on the lOtli of November.
