clear and brilliant, and the tints have a more decided 

 suggestion of blue or violet in the red. During the time 

 of greatest intensity of color, the rosy tints pass through 

 what might be called peach-blow color rather than pure 

 rose-color. They were also more brilliant and of very 

 much longer duration. At times they seemed almost blaz- 

 ing with color, as if self luminous. Then, too, when the 

 shadows of other peaks were projected on such sunlit 

 snowfields and crept up the slope, gradually quenching 

 its color, the contrast between the rosy illumination above 

 and the bluish-gray shadow below was much stronger 

 than I have seen elsewhere. The shadows themselves 

 were bluish gray, and the blue tinge was at times very 

 perceptible. Attractive as these phenomena are wher- 

 ever found, I have never seen them anywhere else so 

 fascinatingly beautiful in their contrasts of color, nor so 

 prolonged in the display. 



On July 6th the western sky was cloudless when the 

 sun set behind very snowy mountains on the Alaska Pen- 

 insula. The illumination was exactly the reverse from 

 that which produces the i Alpine Glow.' Before the sun 

 touched the horizon the snowfields directly beneath the 

 disk and stretching along the ridge either way, glowed 

 with wonderful brightness. They gleamed brighter and 

 brighter like flame itself as the disk neared the hori- 

 zon and slowly sank beneath it. The glow was then 

 quenched with a suddenness that seemed almost start- 

 ling. The air was probably at that height very dry, 

 and too pure and moteless to be of itself as luminous 

 as is common along the horizon beyond which the sun 

 usually sets. Hence the suddenness with which the 

 brilliancy ceased when the sun was actually out of sight 

 and the scanty afterglow in the sky near its place of 

 setting. It was one of the most striking sunsets I ever 

 beheld.
