Report of the Spring Migration of 19 17. 



COMPILED BY WITHER STONE. 



Forty-seven schedules were returned by D. V. 0. C. Migra- 

 tion Corps for the year 1917 as may be seen from the appended 

 list of observers. Additional recruits are particularly desired 

 especially from stations within the ten-mile radius in order to 

 keep this valuable piece of investigation fully up to the standard 

 of past years. Names of competent observers may be sent to 

 Dr. Witmer Stone, Academy of Natural Sciences, Logan 

 Square, Philadelphia, and schedules and instructions will be 

 forwarded at once. 



We should again urge all observers to study more carefully 

 the suggestions contained in the 1914 Report, a copy of which is 

 enclosed with each blank schedule for 1918, in order that they 

 may familiarize themselves with the normal time of arrival of the 

 various species. An unusually early record always suggests a 

 possible error in identification and should be accompanied by 

 notes as to the circumstances of the observation and the 

 methods employed to insure accuracy. Unless such circum- 

 stantial evidence accompanies the record it may be omitted 

 from the printed list. The same conditions apply also to rare 

 and unusual species.
