24 PHOTOGRAPHY FOR BIRD-LOVERS. 



advantage here is that the camera may be left en 

 tirely untended and only returned to at intervals, so 

 that the plates may be changed for fresh exposures. 

 This method, however, leaves too much to chance ; 

 the photographer has no idea of the position 

 of the bird when the picture is taken, and, as 

 nearly all the pleasure and excitement of the work 

 are lost, this method is only to be recommended 

 for emergencies. Worked by the hidden photo- 

 grapher by means of a push button, such an 

 appliance, being truly instantaneous over any 

 distance, is valuable, its chief drawback being 

 its somewhat heavy weight. 



Of other items not much need here be said, as 

 minor fitments used less often will be dealt with 

 as they occur, but it may be mentioned that the 

 camera-case should not only be really waterproof, 

 but stout enough to withstand the corners of rocks 

 and snags of branches which will at times assail it. 



A stout line of good quality is a constant friend, 

 not only for hauling the camera up trees or lowering 

 it down cliffs, but in endless other ways besides; a 

 deep-sea line in two or three pieces of about sixty 

 yards each is just the thing.
