NOTICE. 



When \ve undertook the task of recording 1 the Life- 



D 



Histories of the Birds of Eastern Pennsylvania, we felt sure 

 that the scope of our subject would not carry us beyond 

 the limits of a second volume. In this we have been dis- 

 appointed. The many new facts which have been brought 

 to light through patient study and diligent field-researches 

 since the issuing of our first volume, have so considerably 

 augmented our stock of information as to preclude the 

 possibility of embracing the whole within the limits of a 

 second volume, without making it largely disproportionate 

 m size to its companion. Besides, we had, from the first, 

 contemplated ending the work with a few critical essays 

 upon the songs, changes of habits, and migration of 

 birds. This additional matter would have still further en- 

 hanced the limits and value of the book beyond the expec- 

 tations of the author and his publishers. We have there- 

 fore wisely concluded to reserve the remaining material 

 for a third volume, to commence with the Graffa fores, or 

 Wading Birds.
