1."). Nevada Station (June 25, 18G8). — This place was merely a stage- 

 station in the midst of an inhospitable desert, upon which a few stunted 

 grease-wood bushes constituted the only vegetation in the immediate vicinity. 

 The only birds seen about the station were the ever-present Mourning Doves 

 {Zenmhira carolinensis) and a single pair of Sayornis sai/us, the latter having 

 a nest in one of the out-buildings. The former was particularly abundant 

 about a hill of calcareous tufu, containing many caverns, some distance 

 from the house, the Salpinctcs obsoletns being also common there. On the 

 plain, only Eremopliila alpestris, Ampldspiza Ul'meata, and Rliinognjphus aura 

 were found.

 of the desert, containing a nearly circular lake of about a mile in circuit, 

 and with nearly vertical wall's seventy-five, or perhaps a hundred, feet high. 

 Seen from the top of this wall the water appeared very clear, while the 

 bottom was distinctly visible far out toward the center, where the depth 

 seemed to be immense, since the floor of pure white borate of soda ended 

 abruptly, after which the water was a deep, dark blue. Springs of fresh
