SPRING MIGRATION, continued 



The date of spring arrival, May 7, for eastern Massachusetts is obtained 

 by selecting the earliest dates, as contributed during a series of twenty years, 

 1886-1905, by twenty observers located in thirteen different towns in Mass- 

 achusetts east of the Connecticut river. No measurable difference can be 

 noted in the time of arrival at Springfield and at Boston or in the intervening 

 districts. Treating the notes from these thirteen towns as if they had been 

 contributed from one locality, the record of the first one seen is so uniform 

 that it will be given in full. All the dates of the first one seen are in May 

 and are for consecutive years, beginning with 1886: May 8, 7, 6, 9, 8, 11, 

 7, 7, 10, 7, 4, 7, 8, 6, 9, 6, 7, 9, 4, 5, average xMay 7. If the average date 

 of the first one seen had been calculated for each town separately and then 

 an average made of the resulting averages, the date of May 9 would have 

 been obtained for the final average instead of May 7. 



FALL MIGRATION 



The average date of the first one seen in the fall in southern Mississippi 

 is September 14, and at Raleigh, N. C, September 5. The first was noted 

 at Lexington, Ky., September 3, 1905; St. Mary's, Ga., September 13. 

 1905; Tallahassee, Fla., September 11, 1904; northern coast of South 

 America, October 5, 1900; central Brazil, November 4, 1882.
