 (Quiscalus q. quiscula) this spring, and the comparative 

 scarcity of Robins (Planesticus m. migratorius) , Bluebirds 

 (Sialia s. sialis), and Redwings {Agelaius p. phoeniceus) at

 savanna), March 16, near Leonia, N. J. 



The first paper of the evening was given by Mr. Norman 

 Taylor of the Brooklyn Museum, and was entitled ''The 

 Effects of Temperature on Our Local Flora. ' ' Some interesting 

 correspondences were pointed out between the distribution of 

 plants and the duration of time between the last killing frost 

 in the spring and the first killing frost in the fall. A few 

 colored lantern slides of northern flora were exhibited. 



Mr. Robert Cushman Murphy read the second paper of 

 the evening, entitled "A Historical Review of Bird Migration." 

 The speaker gave an excellent presentation of the phenomena 

 of migration, and the various theories for them which have 

 been advanced.
