Some of the cloud effects were, however, especially 

 beautiful. Photographs of clouds are, as a rule, very un- 

 satisfactory, but many of those taken on this trip show 

 cloud scenery with a beauty rarely equaled. The lights 

 and colors on the clouds seen in the long twilights of 

 those high latitudes, although longer in duration were not 

 more brilliant than in lower latitudes. 



Rose and crimson clouds sometimes lingered in the 

 northern sky during the whole interval between sunset 

 and sunrise. They were very brilliant in Bering Strait 

 during the short bright night of July 11-12. 



As to the color of the sky itself, it was never dark blue 

 north of latitude 55 or 56 always a lighter blue than 

 we have on clear days in middle and lower latitudes. It 

 was deeper blue than the sky along the eastern coast of 

 North America in the same latitudes, but not so deeply 

 blue as in the warmer regions we are more familiar with. 



The colors of sunsets and sunrises were not so varied as 

 at home. This applies both to the sun-glows in the clear 

 sky along the horizon just after the sun's setting, and to 

 the red or crimson colors of the clouds later, and there 

 was little to distinguish them from those of our home 

 experience, either as to shade or intensity of color. The 

 disk of the sun, before setting, was never reddened, but 

 had varying shades from white brightness to golden yel- 

 low. Although the disk never reddened, the afterglow 

 in the sky, near the horizon, was often rose-colored, sal- 

 mon and even orange. Sunrises came so inconveniently 

 early that few observations were made. 



Now and then we had a mirage over the water, when 

 the air was temporarily still enough and the temperature 

 right for them to form, but they were neither so striking 

 nor so frequent as along the coast of Labrador in the same 

 months. Nevertheless, there were one or two which were 

 beautiful for a while, and which linger in the memory.
