Essex, Hertford and Cambridge, but their arrival in these 

 counties was several days later than that of the birds on the 

 western edge in Lancashire and Yorkshire. 



A second large immigration occurred subsequently to this, 

 but lasted only four days ; it was noted in Devon on April 

 the 11th, and in Devon and Hants on the 13th and 14:th. 

 The birds again went north-east, passing through Somerset 

 for over a week, and through AViltshire into Oxford and 

 Nottingham, the eastern ones passing from Hampshire into 

 Surrey and Berkshire. 



By April the 16th Chiffchaffs were reported as paired in 

 Hampshire, and as nesting in Yorkshire on the 21st ; but 

 fiirther immigrants were still arriving in Hampshire on 

 April the 19th and 20th, in Devon on the 23rd, and in 

 Sussex on the 28th. Many of these birds passed throuo-h 

 Somerset and apparently reached Norfolk and Suffolk ; but 

 they must have travelled in a leisurely manner, and were 

 to a great extent overlooked on the way. It seems possible 

 that these later arrivals were on their way to the more 

 noi'thern parts of Europe.
