THE BIRD PHOTOGRAPHER'S OUTFIT 95 
ful when conditions do not permit one to work in 
front of the camera. 
A device which might be arranged on the princi- 
ple of a trap, the trigger to be sprung and exposure 
made when the bait is taken, would doubtless cap- 
ture some interesting pictures. An apparatus con- 
nected with an automatically fired flash-light, has 
been employed by Mr. G. A. Shiras, of Pittsburg, in 
photographing deer at night, with phenomenal suc- 
cess. The connection with the camera shutter was 
so made that the deer, in walking, touched a cord 
which exploded the flash-light, and, at the same mo- 
ment, made the exposure. The light weight of most 
birds, however, requires a much more delicate appa- 
‘atus, While an even greater difficulty is found in 
the movement caused by the release of the trigger, 
which startles the bird just as the exposure is 
made. 
Thus far in my experiments I have been unable 
to overcome these objections, but I trust some other 
bird photographer will be more successful. 
Those who are ambitious in the direction of cliff 
photography I would refer to the Keartons’ admi- 
rable treatise on the subject in their Wild Life at 
Home, for a description of the paraphernalia needed 
and the manner in which it should be used. My 
own experience in this line is limited, and I confess 
to the utter absence of a desire to increase it!
