An Invaluable 

 Companion for 

 Nature Lovers 



The inner circle of the accompany- 

 ing illustration shows the field of view 

 of an ordinary type of Field Glass 

 The outer circle shows in comparison 

 the fie'd of the well known 



BAUSCH & LOMB-ZE1SS 



STEREO PRISM BINOCULARS 



These wonderful glasses give a field of view nine times as great as 

 that of the ordinary Galilean glass, with even illumination and clear definition to 

 the edges. 



The stereoscopic effect enables one to get a better idea of distances 

 and the relative position of objects in a landscape. 



Furthermore, the prism type of construction renders the glass light and 

 compact enough, even in some of the higher powers, to be easily carried in 

 the pocket. 



These binoculars are great favorites with 

 Nature enthusiasts and all lovers of the out- 

 doors. There is a model to meet every 

 need. Send today for attractive illustrated 

 booklet on complete line.
