LETTER XVIII 



TO THE nONOURAHLE DAINES HARRINGTON 



Selborne, Jan. 29, 1774. 



Dear Sir, 

 The house-swallow, or chimney-swallow, is undoubtedly 

 the first comer of all the British hirundines ; and appears 

 in general on or about the thirteenth of April, as 1 have 

 remarked from many years' observation. Not but now 

 and then a straggler is seen much earlier : and, in par- 

 ticular, when I was a boy I observed a swallow for a whole 

 day together on a sunny warm Shrove Tuesday ; which 

 day could not 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 case of the two dreadful springs of 1770 and 1771, 

 they immediately withdraw for a time. A circumstance 

 this much more in favour of hiding than migration ; since 

 it is much more probable that a bird should retire to its 

 hybernaculum just at hand, than return for a week or two 

 only to warmer latitudes. 



The swallow, though called the chimney-swallow, by no 



means builds altogether in chimneys, but often within 



barns and out-houses against the rafters ; and so she did 



in Virgil's time : 



. . . . " Ante 

 Garrula qii^m tignis nidos siispendat hirundo." 



In Sweden she builds in barns, and is called ladu swala, 

 the barn-swallow. Besides, in the warmer parts of luiropo 

 there are no chimneys to houses, except they are I'^nglish- 

 built : in these countries she constructs her nest in porches, 

 and gateways, and galleries, and open halls. 



Here and there a bird may affect some odd, peculiar 

 place ; as we have known a swallow build down the shaft
