 September. 

 In the first half of September, with prevailing westerly 

 winds, there was much departure of our summer visitors, 

 a little passage migration and some small arrivals of winter 

 visitors. During the second half there were one or two 

 short spells of east wind and a certain number of uncommon 

 visitors, as well as passage migration, are recorded. The 

 departure of our summer visitors continued and increased 

 arrivals of winter visitors took place. 



Octobe7\ 

 With variable easterly breezes for the first six days 

 of October a considerable immigration seems to have taken 

 place ; thereafter the weather was of a westerly type and 

 a small, steady stream of migration is recorded. This was 

 chiefly arrivals of winter visitors, very little passage migra- 

 tion being noted. The last of the summer visitors took 

 their departure during the month. 



November. 

 During the first twelve days of November the wind was 

 chiefly north or north-west, thereafter it was easterly up 

 to the end of the month. The feature of this month was 

 the great immigration of Waxwings that took place ; there 

 were also movements of Mealy Redpolls and Northern 

 Bullfinches and a large influx of Siskins. Otherwise the 

 migration for the month was normal in character. 



December. 

 December was mild and the wind chiefly westerly ; no 

 weather movement is reported. Waxwings continued to 

 be recorded from many parts of the country, but except for 

 these there was nothing which calls for notice here.
