stream not far distant. In fact, as a s|iecitic character, nil., i- in this faniilv seems to ))e at its h,wa«t 

 value. 



The character of the hottoni and water itself has much tu do with this, and I remember to have 

 (ished in a small rivulet on one of the suVjalpine meadows not far from Mount Whitney, whose slug- 

 gish waters flowed over a bottom of dark mud, in which the color of the trout simulated very closely 

 its hue; they had lost nearly all the flashing iridescent tints characterizing the same species ciiijlt 

 but a few hours before in another stj-eam, and had become dull and somber-hued. Acci'Ihiimh i ml: 

 this change of color was a correspondingly noticeable difference in habits and motions, and the sev. r.i 

 dozen trout caught that evening for supper were taken out by the hook with the display at very little 

 more gameness than would be noticed in so many horned pout. On the contrary, in the clear, rapi^l 

 current of the mountain stream a flash of sunlight is scarcely quicker than the gleam of gold and silver 

 seen for a single instant as the whirling waters are cut by one of these trout as he makes a rush from 

 his lurking place for some chance morsel which is being borne past him. The western trout are 

 rarely as shy as their relatives of eastern waters, and because of their numbers and the consecjuent 

 scarcity of food are apt to be less fastidious; yet, even when most abundant, due caution must be used 

 if one would be successful, and not every one can catch trout, even in the West. AVith the proper 

 care in concealing oneself, a pool may be almost decimated ere the alarm will be taken, and I have- 

 seen 15 fair-sized trout taken from a single small pool in quick succession. 



The species was named for Agna-Bonita Falls in Volcano (.'icck. iinder the 

 erroneous supposition that the tj'pe came from that creek.
