noted from Scotland on the l^th and 19th. The population 

 of the eastern counties north of Hertfordshire and Essex 

 seems to have taken a longer time to reach its destination 

 than that of the Midlands and western counties, and it was 

 not until after the 22nd of April that any marked increase was 

 observed in that area. 



The progress northward of the successive arrivals can be 

 traced in some detail by means of the " Chronological 

 Summary," particularly by the western route through Wales 

 and the neighbourinfj border counties. 



Nesting operations had already commenced in Devon 

 by the 21st of April, in Lancashire on the 3rd of May, in 

 Kent and Hertfordshire on the 7th, and in Hampshire, 

 Glamorgan, Warwick and Cumberland on the 13th. Nests 

 with eggs were reported from Radnor on the 19th of May 

 and from Somerset on the 22nd.
