to the day's credit, eleven of them being new for the year. Of this 112, 

 twenty-one were warblers and fifteen of them were singing — the songs of 

 four of them being heard for the first time in the writer's experience. 



Comparing the list of species with that of last year it is found that 

 eight species on last year's list were not seen, while eighteen not seen 

 last year are on this year's list. Of the eight not seen five were cer- 

 tainly in the county and probably all were. There can be little doubt 

 that these eight, with several others as well, would have been found had 

 it not been necessary to cut the day short on account of the heavy roads. 

 The return home across country instead of the return to the electric 

 lines must certainly have resulted in more records. But there are other 

 years coming ! 



That the list of species recorded this year is so much larger than last 

 while the weather was so unfavorable and but one person was at work 

 the larger part of the time, is probably due to three causes : First, the 

 migrations were far more crowded than last year, due to the late contin- 

 uation of wintry weather and the three weeks of summer temperature 

 which followed ; Second, to greater activity in the field for weeks previ- 

 ous to the day appointed, during which the localities where the more 

 uncommon breeding species might be surely found were carefully noted ; 

 and Third, to the eight power Bausch & Lomb Zeiss field glasses. Their 

 contribution to the day's record could not be easily over estimated. 

 They are invaluable where quick, precise, all-distance work must be 

 done. They save many steps and no end of exasperation. 



This list illustrates what may be in store for him who may be so 

 fortunately situated that not one but every spring day may be wholly 

 given to study of the birds. He might then hope to compare one day 

 with another, determining the fluctuations which undoubtedly occur in 

 the whole bird movement as well as the fluctuations of the individual 

 species. Such work is greatly needed today. In the list which follows C 

 following the name of a species indicates that it was common on that da)'.
