FIELD GLASSES FOR BIRD 
STUDY 
or equally good for the mountain, sea shore 
or theatre, or wherever a large, clear image 
of an object is desired. 
We carefully examined more than a hun- 
dred makes of field glasses, to select the 
ones best adapted for bird study. 
We found one make that was superior to 
any other of the same price and equal opti- 
cally, and nearly as well made as those cost- 
ing three times as much. 
They magnify about three diameters, and 
have an unusually large field of vision or 
angle of view, making it easy to find a bird 
or keep him in sight. Price $5.00 postpaid.
