the country, counties being populated where the species had 

 not hitherto been recorded. By the 16th these immigrants 

 reached north Wales and on the 17th, 18th and 20th 

 Lincolnshire, Shropshire and Yorkshire respectively. 



The third immigration, also a large one, occurred between 

 the 23rd of April and the 2nd of May, the larger proportion 

 of the birds landing to the west of Hampshire. The course of 

 these birds could also be traced north in the same manner as 

 the last, especially through Wales and the western Midlands. 

 Their influence on the numbers already present in the 

 eastern counties was, however, but slight, as was to be 

 expected considering the area of their arrival. 



A single bird taken at St. Catherine's light on the 5th/6th 

 of May probably indicated the conclusion of the immigration 

 of this species, though passage movements on a reduced scale 

 were traceable through the country up to the third week of 

 the month. 



Nests with eggs were found in Somersetshire on the 

 7th of May, in Kent on the 16th, in Gloucester and Shrop- 

 shire on the 18th, and in Surrey and Radnor on the 21st. 

 There seems to have been a very general opinion that the 

 inclement weather caused a great mortality amongst the 

 earlier arrivals, and Chiffchaffs were reported as being very 

 scarce in certain parts of Devonshire, Kent, Somersetshire, 

 Berkshire, Surrey, Carmarthen, Monmouth, Gloucester, 

 Staffordshire, Nottingham and Yorkshire.
