COLLECTING AND PREPARING BIRDS, NESTS, 



AND EGGS. 

 BY VBBNON BAILEY. 



Collecting Birds. Our present knowledge of birds and their 

 classification has come from a study of specimens, of the dead bird 

 in the flesh, of crops and stomachs, stuffed skins, and skeletons ; 

 and without this foundation the study of birds would not have its 

 deep interest and meaning nor its practical bearing on the economy 

 of our lives. Even our enjoyment of the birds in life, their beauty, 

 song, and friendship, would be far less than it is without the un- 

 derlying knowledge of their life history, the place they fill, and 

 their importance to us.
