The eastern wing, liowever, clung for some time to the 

 south, thus Suffolk was not reached until April the 15th, 

 the day on which the bird was recorded as numerous in 

 Lancashire ; and Cambridge, not until the 21st corres- 

 ponding to the arrival in Westmoreland, while the birds 

 of this movement were not recorded from Norfolk until 

 the 22nd, two days after they had spread in numbers over 

 the whole of the rest of England and Wales. 



Records, however, for further years will be necessary 

 before this unaccountable retardation in the east can be 

 considered as normal. 



It is, however, to be noted that a similar retardation in 

 the eastern counties was observable this year in one or 

 two other species. 



At the end of April and during the first week of May 

 the records show that Willow- Warblers were again arriving 

 on the south coast, but these migrants were apparently 

 birds of passage, and passed rapidly northwards through 

 the country. 



There is evidence of the departure of these birds from 

 this country in at least two places, namely, the north 

 coast of Wales in the west, and the coasts of Norfolk and 

 Suffolk in the east. 



As regards the former we have direct evidence of their 

 departure during the last week of April from the records 

 of land-observerSj and with regard to the east coast there 

 are numerous records from the lights between April 28th 

 and May 7th, and it is extremely unlikely that these should 

 represent an immigration, since in the previous movements 

 only a very few birds struck these eastern lights. 



These records, therefore, taken in conjunction with the 

 facts — 



(i) That the birds struck these lights at a com- 

 paratively early hour of the night ; 



(ii) That they were noted at these lights on the 

 days following their arrival on the south coast ; 



(iii) That no corresponding increase was observable 

 by recorders inland ; 



(iv) That whenever the direction of the flight was
