to have passed through Mid-Wales on May the 3rd, and to 

 have reached North Wales and Yorkshire on the 4th, while 

 the eastern ones reached Oxford on the 3rd, Berks and 

 Suffolk ou the dth, and Norfolk on the 5th. 



On May the 4th a second series of immigratory waves 

 commenced, lasting in an intermittent way until the 17th, 

 and extended, for the first time, to the east of Hampshire. 



On May the 4th and 5th Sand-Martins arrived in Dorset 

 and Hants, on the 6th in Devon and Hants, on the 8th in 

 Hants and Kent, on the 9th and 10th iu Hants, on the 11th 

 in Devon, on the 12th in Kent, on the 15th in Hants and 

 Sussex, and on the 17th in Devon. 



The western birds, as before, passed through Somerset 

 and Wilts into Stafford, Derby, and Mid- Wales, and thence 

 northward cither into Lancashire, or through the Isle of 

 Man to more northern breeding-haunts. 



Many of the eastern birds doubtless stayed in the 

 south, but there was abundant evidence that they also passed 

 northward through Berkshire, Surrey, Essex, Middlesex, 

 and Hertfordshire into Suffolk, Cambridge, Norfolk, and 

 Lincoln. It was doubtful whether any of these birds left 

 the east coast for more northern summer quarters. 



The eighth and final immigration arrived in Hampshire 

 in the early morning of May the 26th, and was noticed 

 at the lighthouses. The birds passed on through Wiltshire 

 and Berkshire into South Wales, Buckingham, and Hertford- 

 shire, and some could be traced into North Wales, whence 

 they doubtless continued in a northerly direction.
