bull's U^t in 1869, aiul contains a vast amount of original matter. 

 The first accounts of the summer hinls of the Pennsylvania mount- 

 ains are contained in Dr. Warren's re|)ort, but owing to the large 

 amount of popular matter that was necessarily incorporated in it, 

 many records of great scientific importance are passed with but cas- 

 ual mention. Many statements are also made on the authority of 

 correspondents in various parts of the State, which have since proved 

 erroneous. 



In 1891 appeared Stone's Summer Birds of Harvey's Lake, the 

 first [)aper dealing exclusively with the birds of the Pennsylvania 

 mountains, followed the next year by Dwight's Summer Birds 

 of the Crest of the Pennsylvania AUeghanies, a much more ex- 

 tensive treatise on the same region. Todd's Summer Birds of 

 Indiana and Clearfield Counties (1893) is the first extensive paper 

 on western Pennsylvania birds, and Jacob's Summer Birds of Green 

 Co. (1893) is another valuable contribution to the ornithology of the 

 same section. 



But few local lists of New Jersey birds have appeared. Scott's 

 Birds of Long Beach (1879) and Laurent's Birds of Five-mile 

 Beach (1892) are the most important, and are both extremely val- 

 uable contributions. Shick's Birds of Seven-mile Beach (1890), 

 which was never completed, is the only other paper on the coast 

 birds. Tiiurber's Birds of Morris Co. (1887) is an excellent list, 

 but unfortunately appeared only in a newspapei'. Stone's Summer 

 Birds of tiie Pine Barrens (1894) summarizes our knowledge of the 

 breeding birds of this region to date. The only other extensive list 

 of the birds of the State is Nelson's Birds of New Jersey (1890), 

 which is unfortunately very unreliable, being practically a reproduc- 

 tion of Dr. Abbott's 1869 list without corrections and with some ad- 

 ditional errors. 



The following list contains all the important publications relating 

 exclusively to the birds of Pennsylvania and New Jersey, arranged 

 chconologically.
