to keep the mirror moving so that no part of the 

 nest will be, better illuminated than another. 



So much for the ground builders. The nests 

 placed from one to five feet from the ground are 

 the most satisfactory to work upon. They are 

 easy to get at, generally require but little pre- 

 liminary preparation 

 or arrangement, and 

 they offer, from the 

 nature of their sur- 

 roundings, far better 

 possibilities for fine 

 results than do the 

 ones that are placed 

 either high up in the 

 trees or on the ground. 

 The tripod should 

 be made sufficiently 

 long to elevate the 

 camera from six inches 

 to a foot above the 

 level of the nest and so tilted as to point the 

 lens diagonally downward at it. Should the nest 

 be placed so high up in a bush, too small to bear 

 a person's weight, as to make it impossible to 

 reach it by the aid of the ordinary tripod, sticks 

 must be cut and bound tightly to the legs of the 

 tripod, thus lengthening them to the desired ex- 

 tent. Upon several occasions I have made my tri-
