In photographing nests it is neces- 

 sary to use small stops in order to 

 bring all planes into sharp Focus. 1 

 usually use U. S. 32 or 64 and give 

 long exposures, from five to ten or 

 more seconds, of course depending 

 upon the light and conditions. Wind 

 is the great bugbear in this work and 

 I have spoiled many plates on ac- 

 count of it. 



The nest and eggs of the downy 

 woodpecker were discovered in an old 

 stump near my home. I found it 

 while the old birds were digging out 

 the hole. By the use of a small mir- 

 ror inserted in the hole I was able to 

 see when the first egg was laid. I 

 then cut out a square piece on a level 

 with the nest. This was nailed in 

 place, and by taking it out at an}' 

 time I was able to watch the pro- 

 gress. Five eggs were laid w r hich, in 

 the course of time, hatched out into 

 five young woodpeckers. I was un- 

 able to get the fifth one out of the nest 

 without hurting it. 



The nest and eggs of the sparrow 

 hawk were found in an old nest of a 

 flicker. The sparrow hawks have oc- 

 cupied this nest for several years. 



A Plea For More Extensive Photog- 

 raphy of Living Fishes.

I Listor} goes to show that the writer is 

 an long the very firsl few who have been 

 successful in the matter of scientific 

 photography of living fishes in aquaria. 

 A full report upon the subject, with 

 many half-tone reproductions, appeared 

 in Volume XIX of the Bulletins of the 

 United States Fish Commission for 

 [899 (Washington, Government Print- 

 ing Office, 1901), and since then in 

 various foreign and domestic maga- 

 zines devoted to photography and nat- 

 ural science. To all these the reader 

 is referred for the technique of this 

 class of work. After the Fish Com- 

 mission had published my contribution 

 along these lines, a number of well- 

 known scientific photographers came 

 into the field who undertook similar 

 experiments, and it was not long before 

 the elegant results of such men as 

 Dugmore and Spencer of New York 

 Aquarium began to appear in our best 

 magazines and various reports devoted 

 to such subjects. 



All this occurred a number of years
