A GREAT FROST 223 



and we may suppose that when the weather moderated 

 the surviving millions redistributed themselves over 

 the southern counties from Somerset to Kent ; also 

 that many birds had been continually slipping away 

 across the Channel. Many of our migrants, which 

 have not a strict migration like the swallow and

 throughout the year, do annually come down in 

 batches to the south and remain for a month or so, 

 in some cases until December, then vanish, and these

 appear to form a body or race distinct from the 

 earlier migrants having their own seasons and perhaps 

 a route of their own. 



To return to the great visitation of birds in Decem-

 with storms of wind and sleet and occasional flurries 

 of snow, until January 21, when the cold became
