NATURAL HISTORY OF SELBORNE. 69

SELBOKNE, Aug. 30^,- 1769. 



IT gives me satisfaction to find that my account of the 

 ousel migration pleases you. You put a very shrewd 

 question when you ask me how I know that their autumnal 

 migration is southward ? Was not candour and openness 

 the Tery life of natural history, I should pass over this 

 query just as a sly commentator does over a crabbed 

 passage in a classic ; but common ingenuousness obliges me 

 to confess, not without some degree of shame, that I only

 suspect since that they may come to us from the westward ; 

 because I hear, from very good authority, that they breed 

 on Dartmoor, and that they forsake that wild district 

 about the time that our visitors appear, and do not return

I have taken a great deal of pains about your salicaria

 (and trust you will soon become convinced of the same) 

 that it is no more nor less than the Passer arundinaceus

 to be entirely omitted in the British Zoology ; and one
