a week ; but it is perfectly clear from a study of the Time- 

 table, and by noting the successive increases and decreases 

 at different points, that wave after wave of birds arrived 

 along the south coast and swept due north throughout the 

 country. 



Some appear to have left the north coast of Wales and to 

 have travelled north through the Isle of Man, while others, 

 taking a north-easterly direction, left the east coast by 

 Norfolk and Lincoln. 



There seems to be no doubt that the bulk of our own 

 breeding-birds arrived with the earlier part of this movement 

 and during the previous immigrations. By April the 28th a 

 nest with eggs was reported from Devonshire, and by the end 

 of this last immigration the Willow- Warbler was reported as 

 resident in its full numbers from several parts of the country. 

 After April tlie 22nd there was a lull in the migratory 

 movements until the 25tl), but from that date onwards till 

 May the 4th there was another large immigration in successive 

 waves. The records show that these waves arrived on the coasts 

 of Hampshire and Kent on the 25th, in Devon and Dorset 

 on the 2Gtb, Hampshire on the 27th, Hampshire, Sussex and 

 Kent on the 28th, Hampshire on April the 30th and May 

 the 1st, Cornwall and Hants on May the 2nd, and Hampshire 

 and Dorset on the 4th. 



As was the case in the latter part of the last immigration, 

 the records show that these birds did not stop, but continued 

 travelling in a northerly direction, and by means of the 

 annexed Time-table the routes can be traced with very fair 

 accuracy. It should again be noted that we have evidence 

 on May the 10th of birds having passed through the Isle of 

 Man and on the 14th of others having left the east coast. 



From May the 7th to the 16th a third series of immigratory 

 waves rea hed the south coast, the birds arriving in Devon 

 continuously between those dates. On the 8th they arrived 

 in Cornwall and Dorset, on the 10th in Sussex, and on the 

 11th and 12th in Hampshire. On the 15th a very large 

 wave arrived in the last-named county, and on the 16th in 

 Dorset.
