past when Oology was in the forefront. In our opinion Oology 

 as such and such alone will never be able to stagger to its feet 

 again. As a part of Ornithology in the broad sense it has its legiti- 

 mate and necessary place, but as a distinct science it has and ever 

 will prove a failure, for the very simple reason that it does not 

 possess within itself the elements of a separate science. L. J. 



The Birds of the Rockies. By Leander S. Keyser. 



In this large octavo there is a sympathy of the author with his 

 mountain surroundings and of the artist, Louis Agassiz Fuertes, 

 with the conception of the book, that one rarely finds. No three-color- 

 process colored pictures here, but finely executed colored engravings, 

 full-page half-tone and sketchy marginal engravings. A good, clear 

 and clean type makes easy reading of an entertainingly written ac- 

 count of a bird-lover's experiences in the Colorado mountains. If 

 the author possesses any fault of execution it lies in giving himself 



too fully to the enamoring influences of the mountain environment. 

 The price of the book, reduced to $1.50, will make it appeal to 

 every lover of outdoors. L. J.

I will quote the following as worthy of special mention: "During 

 the summer the Turkey Vultures (Cathartes aura) were unusual in 

 their northern flight. They have been seen as far north as Wil- 

 liamsport, and a few at State College, Center county. * * * During 

 the fall a Cardinal (Cardinalis cardinalis) was seen by us in Center 

 county. * * * I have evidence that the American Crossbill (Loxia 

 curvirostra minor) nests in the central part of Pennsylvania, in the 

 fact that during the middle of the summer of 1902 a pair of old 

 birds accompanied by four of their young were seen for two days 

 upon the State College campus, in Center county, feeding upon the 

 mites of the cockscomb elm gall. During the winter, which was 

 unusually long and severe, there was a decided immigration of 

 northern birds into our State. Especially remarkable among these 

 were the Pine Grosbeak (Pinicola leucura), the Crossbills (both 

 specius of the genus Loxia), the Snowflake (Passerina nivalis), 

 and the Pine Siskin (Spinus pinus). The severity of the winter 

 resulted in killing most of the Quail (Colinus virginianus) of our 

 State, many of the Wild Turkeys and some of the Ruffed Grouse. * 

 * * * During the early portion of this spring (1904) there has been 

 an unusual flight of the aquatic birds. In the vicinity of Harris- 

 burg, gunners have shot several species of Wild Ducks, the Hol- 

 bcell's Grebe, several specimens of the Whistling Swan (Olor co- 

 lumbianus), and one specimen of the Trumpeter Swan (Olor 

 buct inator). We have been fortunate in securing speciments of these
