and the snow will reflect them. Therefore, in exposing 

 for light objects, the dark ones will be under-exposed; and 

 vice versa, exposing for the darker objects, the sky, ice, 

 and snow will be so much exposed that they will melt into 

 an opaque mass on the negative. To be certain at all, one 

 should have a good dark room, and develop some plates 

 daily to enable him to keep in touch with the quality of light. 

 Films work better than plates, the thinness of the cellu- 

 loid gives less halation and more color values, but the only 

 proper outfit for Arctic photography is composed of iso- 

 or orthochromatic plates to be used in conjunction with 

 color screens of various density. To be prepared for all 

 conditions of work in the Arctic regions a number of lenses 

 from the shortest wide angle to a telephoto attachment are 

 indispensable. 



One of the professors, older than the rest, had fallen 

 behind the advance guard, and joined me. We sat down 



upon a projecting piece of 

 ice, ate our luncheon and 

 drank some of the clearest 

 and finest ice-water imag- 

 inable. I spoke of the sur- 

 passing beauty, the fine 

 color scheme, of the sur- 

 roundings. He, in all 

 probability, paid not the 

 least attention to that, but 

 gave the water on the 

 glacier, the hole in the ice, 

 and other things, their 

 proper scientific names, and 

 was happy in his way. 



According to his aneroid 

 barometer, we had climbed 

 upward of 3100 feet, and 

 estimated that we had 

 walked about five miles 

 A SLIP upon the eternal inland ice, 



which covers all of Green- 

 land. Large nails on the soles of our shoes helped 

 us along considerably, but did not always prevent a
