THE HOUSE-MARTIN. 



Chelldon urh'ica (L.), 



The jirst immigration o£ this species arrived in Cornwall 

 on the 13th o£ April. During the previous week a few 

 isolated stragglers had been observed in the southern counties, 

 but nowhere in any numbers. The bulk of the birds passed 

 straight onwards, and were recorded as far north as Dumfries 

 on the IGth ; but a small portion took a more easterly 

 route, and spreading through the eastern counties probably 

 passed on to the continent. 



The second immigration was not a very large one. It M'as 

 first noted in Devon and Hampshire on the 18th ; a second 

 arrival took place in Devon on the following day, and a third 

 in Dorset on the 23rd, most of the birds passing northwards 

 through the western counties. 



A third small immigration landed on the same stretch 

 of coast on the 25th and 26th. These birds took a more 

 easterly course than their predecessors, and spreading through 

 Sussex, Kent, and the eastern counties, apparently passed 

 out of the country. 



On the 26th the /b?/r^/i and main immigration of this species 

 commenced. Numbers were recorded from Glamorgan on 

 the 30th, and as the}' were not observed in Devon or Somerset 

 on either that or the preceding day, it seems evident 

 that they first landed on the south coast of Wales. This 

 immigration was followed by an increase in Wales and 

 Wiltshire. On the 4th, 5th, and 6th of May House-Martins
