not only the published records of Bendire, Belding, Anthony, Mearns, 

 Merrill and others, but of the unpublished observations of a number of 

 observers residing in different parts of the State, but mainly, naturally, 

 west of the Cascades. These records are wisely given on the authority 

 of the observer who made them, for while in most cases doubtless thor- 

 oughly trustworthy, the particular subspecies to which, in some instances, 

 they purport to relate seems open to question, as in the case of some of 

 the finches and sparrows. The arrangement and nomenclature of the 

 A. O. U. Check-List have been adopted, but in respect to recent changes 

 in the latter the later 'Supplements,' appear to have been overlooked. 

 The List was prepared as a thesis for the degree of M. S. in the Oregon 

 Agricultural College. It forms an excellent basis for further detailed 

 work, and will doubtless prove not only a great convenience but a stimulus 

 to future workers. — J. A. A. 



Proceedings of the Delaware Valley Ornithological Club.' — The fifth 

 annual report of the proceedings of the Delaware \'alley Ornithological 

 Club appears under the title ' Cassinia : An Annual devoted to the Orni- 

 thology of Penns^'lvania and New Jersey,' and forms a well printed 

 brochure of 60 pages and two plates. The frontispiece is a full-length 

 portrait of John Cassin, and the first article is, very appropriately, a bio- 

 graphical sketch of this eminent Philadelphia ornithologist, by Mr. 

 Witmer Stone. His brilliant career as an ornithologist is traced briefly 

 and sympathetically by one upon whom, at least ofiicially, the Cassinian 

 mantle has fallen. 



Mr. Francis R. Cope, Jr., gives an annotated list of the summer birds 

 of parts of Clinton and Potter Counties, Pennsj'lvania, numbering 76 

 species, observed June 21-28, 1900. Several pages of introductory 

 remarks relate to the changes in the fauna and flora of the Pennsylvania 

 mountains through the removal of the original forest. "Wherever, 

 indeed," says the author, "the original forest is disappearing under axe 

 and fire, especially in those sections where the hemlock and other conifer- 

 ous trees are being cut away, there just as surely we may look for the 

 disappearance of most of our boreal birds and plants." Again, "where 

 those forests still exist in large tracts, as, for example, they did a few 

 years ago on North Mountain, there we find a very strong, if not a pre- 

 dominating, tinge of the Canadian fauna. On the other hand, where 

 they have been entirely destroyed or broken up into isolated patches, 

 those birds which may be regarded as typical of the Alleghanian fauna 

 are in the majority." 



Mr. William L. Baily describes his successful attempt to photograph a 

 Nighthawk's nest and young, and an accompanying plate gives views of 



' Cassinia, A Bird Annual : Proceedings of the Delaware Valley Ornitho- 

 logical Club, No. V, 1901. 8vo, pp. 60, pll. 2. April, 1902.
