-^ Photography by Day and by Night 



pictures record new facts in natural history. In my first 

 book, for instance, there is a picture of a lioness making 

 off with her tail raised high in the air in a way no artist 

 would have thought of depicting, and no naturalist have 

 believed to be characteristic. 



In the course of my labours I had to overcome every 

 description of obstacle, and had constantly to be making 

 new experiments. By the time I had got things right 

 I had so small a stock of materials left at my disposal 

 that I ought to congratulate myself upon my subsequent 

 success. The number of good pictures I secured was far 

 less than I had originally hoped for, but on the other 

 hand it far surpassed what, in those moods of pessimism 

 which followed upon my many failures, I had begun to 

 think I should have to be contented with. 



Among my successful efforts I count those which record 

 the fashion in which the lion falls upon his prey, first 

 prowling round it ; and those which represent rhinoceroses 

 and hippopotami, leopards and hyenas and jackals, 

 antelopes and zebras making their way down to the water- 

 side to drink ; those also which show the way in which 

 hyenas and jackals carry off their spoils, and the relations 

 that exist between them. But a point of peculiar interest 

 that my photographs bring out is the way in which the 

 eyes of beasts of prey shine out in the darkness of night. 

 I have never been able to get any precise scientific 

 explanation of this phenomenon. I have often seen it for 

 myself in the wilderness. Professor Yngve Sjostedt, 

 a Swedish naturalist, who has travelled in the Kilimanjaro 

 region, tells us that he once saw, quite near his camp,
