Neglecting the first scattered arrivals, which were noted 

 during the last week of March, we find the Swallow 

 first arriving in numbers on the coast of Dorset on April 1st 

 and again at Kingsbridge in Devon on the 4th. These 

 flocks soon split up and made their way northwards through 

 Somerset into Wales, and even as far as Lancashire, while 

 some spread eastwards through Essex and Norfolk. On 

 April 7th a number again passed through Devon and 

 followed the lines of the former arrivals, passing still 

 further into Wales, while the eastern wing arrived in 

 Sussex and Surrey on the 8th and 9th. 



The second immigration of note was recorded from various 

 points in Somerset on April 11th, and the fact that the 

 numbers in Devon on that day were small shows that these 

 birds must have passed over quickly, possibly in the early 

 morning, into Somerset. The route of this migration is 

 clearly traceable through Wales and the neighbouring 

 counties of England, some of the flock reaching Monmouth 

 and Staffordshire on April 13th, Radnorshire on the 14th, 

 and Angiesea on the 15th. These evidently passed on as the 

 numbers at each place specified fell on the following day. 



The occurrence of the third immigration was shown by 

 the appearance of large numbers in Devon on the 14th and 

 15th April, and on the Sussex coast a day later. Both 

 wings of this movement can also be clearly traced as they 

 moved north. The western wing followed the route of the 

 previous ones, while the eastern wing passed through 

 Surrey, Berks and Herts to Essex and Norfolk. By the 

 19th the earlier arrivals had reached Durham, Westmore- 

 land and Cumberland. 



In the fourth immigration, which lasted from the 17th 

 to the 20th of April, the birds were apparently travelling 

 along a front which extended from Devon to Sussex. 

 Those individuals that, after striking in Devon, formed the 

 western wing of this movement, followed the track of the 

 former immigrants, and some of them could be traced 

 through Wales to the Isle of Man, which was reached on 

 the 27th April, doubtless on their way to Scotland. Those 

 birds which arrived in Hampshire at this time appear to
