During May 30 and 31, and June 1 and 3 steady cold north 

 or northeast winds prevailed and during the two latter days 

 with such force that only on the southern edges of woodland 

 could warblers be found. At this time the trees were quite 

 generally leaved out, furnishing an abundance of insect life. 

 Thus confronted by favorable present conditions and those 

 adverse for migrating the birds were disposed to linger. A 

 feeling of contentment seemed to reign among them. They 

 became extremely fat in marked contrast to their previous 

 half-starved condition and the tree-tops resounded with their 

 songs. The cold weather continued till the 9th of June and 

 the migrants remained in considerable abundance during 

 most of that time. However, a noticeable thinning out of 

 their numbers occurred gradually till the 9th was reached, up- 

 on which date they vanished completely. In sum'ming up it 

 can be said that the warblers became common from the date 

 of their main arrival, May 12th, and continued here in 

 abundance till June 2nd and were even fairly common till 

 their departure on the 9th of June. This period of long 

 duration is a singular fact in itself, but it is even more re- 

 markable when the abundance of the miigrants during their 

 entire stay is considered. If the count is made from the time 

 when the first stragglers arrived. May 8th, their continuance 

 here embraced more than a month, — 33 days. 



The extreme lateness of the season is clearly shown by the 

 following migration table and in lesser degree by the table 

 showing a comparison between the condition of certain 

 flowers, trees and shrubs for this year and for the spring of 

 1906:
