EXAMPLE OF THE MANNER OF USING THIS BOOK. 
Suppose you meet with an owl in the woods. It is 
larger than a crow, and must therefore be on Plate I. or 
II. On Plate I. there is no bird like it, on Plate JI. 
there are three owls resembling it. The first, No. 21, 
the great horned owl, is so much larger than this bird, 
compared with the crow on the same plate, that it cannot 
be the one you want. Nos. 22 and 23 are alike in size 
and color. One has larger ears than the other, but you 
may not be able to see Beek in your owl on the tree. 
The long-eared owl, No. 22, has the feathers of the belly 
barred, ‘that 18, the spots run in bars crosswise of the 
feathers ; while the short-eared owl, No. 23, has the breast 
and belly streaked, that is, the spots run lengthwise of 
the feathers. Which is like your owl?
