The old tortoise, that I have mentioned in a former letter, 

 still continues in this garden; and retired under ground

 spend the greatest part of the day on their nest-trees when 

 the weather is mild. These rooks retire every evening, all

 ceded a few minutes by a flight of daws that act as it were 

 as their harbingers.

 then a straggler is seen much earlier ; and, in particular, 

 when I was a boy, I observed a swallow for a whole day toge-

 fall out later than the middle of March, and often happened 

 early in February. 



It is worth remarking, that these birds are seen first about 

 lakes and mill-ponds ; and it is also very particular, that, if 

 these early visitors happen to find frost and snow, as was the 



* A pretty large flock of crossbills visited Ambleside, in Westmoreland, ia 

 October, 1828, frequenting the plantations of young larches. — W. J.
