[ 104 J 



the air be hot and dry, the gnats die of them^ 

 fdves, and even the Swallows will be found fa- 

 mifhed for want, and fall down dead out of the 

 air, their food being taken from them. In like 

 manner, when cold weather comes in, the infcLts 

 all die ; and then of necefiity the Sw^allows quit 

 us, and follow their food wherever they go. This 

 they do in the manner Î have mentioned a|)Ove ; 

 for fometimes they are feen to go off in vail 

 flights like a cloud y and fometimes again, when 

 the winds grow fair, they go away a few and a 

 fev/, as they come, not (laying at all upon the 

 coaft. 



" This pafilng and repaiÏÏng of the Swallows 

 is obferved no -where io much, that Î have heard 

 of, as on this eahern coait ; namely, from above 

 Harwich to the call; point of Norfolk, called 

 Winterton-Nejs, north ; v/hich is all right againil 

 Holland. We kncv/ nothing of them any far- 

 ther north, the palTage of the fea being, as i fup- 

 pofe, too broad from Flamborough Head, and the 

 fnore of Holdernefs in Yorkfhire, &c."
