It feems to follow therefore, from this filence in others, that 

 fwallows cannot be accommodated for their winter refidence in 

 any part of the vaft continent, except in the neighbourhood of 

 Senegal. But this is not the whole objection to fuch an hy- 

 pothesis. 



If the fwallows of Europe, when they difappear in thofe parts, 

 retreat to the coaft. of Senegal, what necefiarily follows with re- 

 gard to a Lapland fwallow ? 



I will fuppofe fuch a bird to have arrived fafely at his winter 

 quarters upon the approach of that feafon in Lapland ; but it 

 muft then, according both to Monf. Adanfon's and de Buffon's 

 account, return to Lapland in the fpring, or at leafl fome other 

 fwallow from Senegal fill its place. 



Such a bird immediately upon its arrival on the Southern coaft 

 of Spain would find the climate and food which it defired to at- 

 tain, and all proper conveniences for its neft : what then is to be 

 its inducement for quitting all thefe accommodations which it 

 meets with in fuch proration, and pufhing on immediately over 

 fo many degrees of European continent to Lapland, where both 

 martin and fwallow can procure fo few houfes to build upon ? 

 What alfo is to be the inducement to thefe birds, when 

 they have arrived at that part of the Norwegian co ift which is 

 oppofite to the Ferroe ifSands, to crofs degrees of fca, in order to 

 build in fuch fmall fpots of land, where there are ftill fewer 

 habitations ? 



The next fact I have happened to meet with, of a bird's being 

 feen at a confiderable diflance from the more, is in Dr. For- 

 mer's lately publifhed tranflation of Kalm's account of N. Ame-
