THE GUIDE TO NATURE— ADVERTISEMENTS 
XIII 
To Help the Eyes See More and Farther 
— in the Woods, the Air, on Land or Sea 
T HE eyes of man function at compar- 
atively close ranges. Unaided, they 
limit his enjoyment of outdoor life to his 
immediate surroundings and restrict his 
usefulness in many operations. 
But through optics he has gained other 
and far-seeing eyes to help his own. Binoc- 
ulars are made to lift his horizon and 
broaden his landscape, to unveil Nature’s 
inaccessible reaches, to expose hidden 
dangers of the deep. 
On every vessel of our Navy, large or 
small, with our forces on land and our 
heroes in the air, the binocular made an 
unparalleled war record. And we were 
its chief source of supply, meeting our 
government’s crisis with more than twice 
as many binoculars in a week as we for- 
merly produced in a year! 
Now, in the ways of peace, the binocular 
is giving service no less varied and helpful. 
What autoist does not multiply by many 
times the interest of his tours, when ac- 
companied by his binocular? Tourist, 
aeroplanist, sportsman, yachtsman. Nature 
student — all depend upon it to increase 
their vision and their pleasure. 
Nor is this the only optical product which 
adds to the comfort, safety and efficiency 
of life. The microscope, ophthalmic and 
photographic lenses, projection apparatus, 
military instruments and others combine 
to give a service to the world, which we 
are proud to have been developing along 
lines of precision and quality since the 
middle of the last century. 
Write for literature on any optical product in 'which you are interested.
