hiding than migration ; fince it is much more probable, 
that a bird flrould retire to its hybernacuiu7n at hand, 
than return for a week or two only to warmer latitudes. 
This fwallow, though called the chimney-fwal-low, by 
no means builds altogether in chimneys ; but often with- 
in barns and out-houfes, againft the rafters : and fo fire 
did in Virgil’s time :

In Sweden fhe builds in barns, and is called ladu fwala^ 
the barn-fwallow. Belides, in the warmer parts of Eu- 
rope, there are no chimneys to houfes except they are 
Engliflr-built. In thefe countries Are conftrudts her 
neftin porches and gateways, galleries, and open halls. 
Here and there a bird may affedl fome odd, peculiar place; 
as we have known a fwallow build down the fliaft of an 
old well, through which chalk was formerly drawn up, 
for the purpofes of manure ; but in general with us, this 
birundo breeds in chimneys, and loves to haunt thofe 
flacks where there is a conftant fire, no doubt for the 
fake of warmth. Not that it can fublift in the immedi- 
ate fhaft where there is a fire ; but prefers one adjoining 
to that of the kitchen, and difregards the perpetual, 
fmoke of that funnel, as I have often obferved rvith fome 
degree of wonder. - Five or fix or more feet dowur the 
chimney does this little bird begin to form her nefl about 
the middle of May, which confifts, like that of the houfe- 
martin, of a cruft or fliell, compofed of dirt and mud, 
mixed with fhort pieces of ftraw, to render it tough and 
permanent
