tened in trees or on the sides or cornices of barns or sheds. It is needless to say 
that English Sparrows shculd not be allowed to use these boxes. By tying suet to 
limbs of trees in winter, and providing a small board upon which grain, crumbs, 
etc. may be sprinkled, large numbers of winter birds may be fed; of these, prob- 
ably only the Chickadees will remain to nest, if they can find a suitable place. 
How To Study Birds.—This refers, not to the scientific, but to the popular 
study of our birds, chiefly in the field. We can learn many very interesting 
things by watching our birds, especially during the nesting season, and the habits 
and peculiarities of many are still but imperfectly known. One thing to be im- 
pressed upon the student at the start is the need of very careful observation before 
deciding upon the identity of a bird with which you are not perfectly familiar. A 
bird’s colors appear to differ greatly when viewed in different lights, while in look- 
ing up in the tree tops, it is often impossible to see any color at all without the 
aid of a good field glass. By the way, we would advise everyone to own a good 
pair of these, for, besides being almost indispensable for bird study, they are 
equally valuable for use at the sea shore, in the mountains or at the theatre. [We 
have examined more than a hundred makes of field glasses to select the one best 
adapted to bird study, and at a moderate price. We found one that was far super- 
ior to any other at the same price, and was equal to most of those costing three 
times as much. It gives a very clear image, magnifies about four diameters and 
has a very large field of view. It comes in a silk-lined, leather case, with cord for
