A MONTH ON KENTISH KNOCK LIGHTSHIP 37 



it was observed moving to the south-south-west, south, 

 and south-east ; and as an immigrant, to the west and 

 north-west. It participated largely in the southerly 

 migrations, both by day and night, during the latter 

 half of September. It was also the most frequent visitor 

 to the light, and was never absent from any of the night 

 movements. As with other species, its pronounced 

 flights from east to west were not observed until 8th 

 October, but after that date it took a prominent part in 

 all the great westerly flights. It was present in numbers 

 during the great night migration of 17th to i8th October.
