A communication was also read from Mr. Plarry Gordon White, of

October 20, i8go. — Six members present. 



Mr. Stone read a paper on the "Spring Migration of 1890, at Phila- 

 delphia," which consisted of a general summary of the work done by 

 the members, with suggestions as to the probable lines of flight of 

 migrating birds in the Delaware Valley. The paper was based upon a 

 careful study of individual records taken at the following stations dur- 

 ing the spring : Tinicum, Delaware Co., Pa., J. Harris Reed ; Haddon- 

 field, N. J., Samuel N. Rhoads ; Haverford, Delaware Co., Pa., Charles 

 J. Rhoads ; Wynnewood, Montgomery Co., Pa., William L. Baily ; 

 Germantown, Philadelphia, Pa., Witmer Stone ; Olney, Philadelphia, 

 Pa., George S. Morris. Charts were also exhibited showing a method 

 by which the so-called "bird waves" could be illustrated in a graphic 

 manner. [See The Auk, 1890, p. 298, and 189 1, p. 194.] 



December i, i8go. — Six members present. 



Mr. S. N. Rhoads read a communication from Mr. Caleb S. Cope, 

 recording the occurrence of the Wild Pigeon {Ectopistes migra tonus) 

 in Washington, which seems to be the first mention of this species from 

 west of the Rocky Mts. [The Auk, 1891, p. 310.] 



A letter was also read from Mr. Pfluger, of Portland, Oregon, re- 

 garding the introduction of German Song Birds at that place. He 

 stated that about 600 of these birds, including Chaffinches, Goldfinches, 

 Linnets, Song Thrushes and Siskins had been Hberated in the spring, 

 md that all the species were seen during the following autumn, the 

 inches having increased in numbers. They did not wander far from 

 Portland during the winter, and a later communication stated that they 

 vere busy nesting in the parks and surrounding country in the spring of 

 1891. Next year another importation, including Blackbirds and Night 

 ngales, will be liberated.
