From the 9th onwards the numbers of immigrants increased, and there 

 was no day and very few nights when this species was not noted 

 at several of the east-coast lights travelling towards land. In many 

 cases they were seen passing in flocks all day, and in some instances 

 this continued for days at a time. The lights at which this species 

 was recorded extended from the Inner Dowsing Lt.-v. off the Lincoln- 

 shire coast to the Varne Lt.-v. in the Straits of Dover, and in every 

 instance the birds arrived from the east. It is, however, uncertain in 

 what direction birds observed on many nights at Dungeness Lt. (Kent) 

 were travelling, though, taken in conjunction with the other obser- 

 vations, it seems probable that they also were going westwards. The 

 onlv evidence of an emigratory movement was a single observation at 

 the Varne Lt.-v. on October the 14th, when a few birds were observed 

 going southwards. 



The immigration on the east coast was at its height from October 

 the 11th to the 21st, and on several days birds were noted making for 

 land from as many as eight different light-stations off the coasts of 

 Lincolnshire, Norfolk, Suffolk, Essex and Kent. From the 22nd to the 

 end of the month immigration was continuous, but the numbers of birds 

 were not so great. 



On land great increases were noted in Lincolnshire on the 10th, 

 in Warwickshire on the 18th, in Suffolk on the 18th, 20th and 21st, and 

 in Kent on the 26th. 



During the first ten days of November the immigration still continued 

 on the east coast, though the number of birds decreased. 



On the night of November the 1st a few were recorded from the 

 Ilanois Lt. (Channel Islands) and from the St. Catherine's Lt. ; on 

 the 2nd/3rd hundreds were recorded from the former and a few from 

 the latter, while on the 4th/5th and 5th/6ih great numbers were 

 recorded from both these lights, and also on the latter night from the 

 Bishop Bock Lt. (Isles of Scilly) ; lastly on the 6th/7th at Bishop 

 Rock Lt. and at St. Catherine's Lt. 



On the 6th, 7th, and 8th flights were noted with Starlings and various 

 species of Thrushes passing Bishop Bock Lt. in a westerly direction. 



Numbers of Sky-Larks were recorded on the 7th/8th from the Wolf 

 Bock (Cornwall), Bishop Bock, St. Catherine's, Dungeness and Hanois 

 Lts., on the 9th/10th from the Bishop Bock Lt. and North Goodwin 

 Lt.-v. (Kent), and on the lOth/llth from the Hanois Lt. 



Unfortunately it was impossible to say whether the migrations noticed 

 at these southern lights referred to birds going south or west, as the 

 direction of the flights could not be ascertained. 



It is equally possible that they were emigrants going south or birds 

 passing west along the Channel coasts : in favour of the latter view 

 is the fact that during that time birds were observed nearly every 

 day at the east-coast lights making for the land.
