After this date no further arrivals took place in the west, 

 but in the east they again began to come into Sussex on the 

 14th ; a very heavy immigration took place into Hampshire 

 on the 16th, and the long migratory wave terminated on 

 the 18th with the advent of sn)aller numbers in Hampshire 

 and Kent. 



The birds composing this immigration seem to have followed 

 much the same course as the preceding one of May the 4th, 

 and as each component detachment arrived its course was 

 ascertained to be in a northerly direction. The western 

 birds were noticed first in Somerset and Wilts, whence 

 they spread gradually day by day through South Wales 

 and Stafford, Mid- Wales, Shropshire, and the western 

 Midlands, into North Wales, Derby, and Cheshire. Some 

 of the more western birds then departed from North Wales 

 and continued their course northwards through the Isle of 

 Man, while the remainder spread across Lancashire and West 

 Yorkshire into Westmoreland and Cumberland. 



The course of the eastern birds could not be traced as far 

 north as that of the western, but it was evident that they spread 

 mainly through Surrey into the counties across the Thames, 

 viz., Berks, Bucks, and Herts, and thence into Essex, 

 Suffolk, Cambridge, and Lincoln ; and it is possible, though 

 there is at present no direct evidence of it, that, like the 

 Wheatear, many leave this country again by the east coast. 

 By the time this extensive movement was over, the reports 

 which began to come in showed that the earlier arrivals had 

 settled down and commenced incubation, a nest and eggs 

 being reported from Wiltshire on May 18th. On the 15th 

 Whitethroats were nesting in Berkshire, and on the 20th and 

 21st in Yorkshire and Northumberland. 



The last immigration took place on May the 21st, when 

 small numbers arrived in Devonshire, followed by similar 

 arrivals in Hampshire on the two succeeding days, but beyond 

 their place and date of arrival nothing further was recorded 

 of their movements.
