LETTER XXXI. 



'To the same. 



SELBORNE, Sept. 14^, 1770. 



EAR SIR, You saw, I find, the ring-ousels again 

 among their native crags ; and are farther assured 

 that they continue resident in those cold regions 

 the whole year. From whence then do our ring- 

 ousels migrate so regularly every September, and 

 make their appearance again, as if in their return, 

 every April ? They are more early this year than 

 common, for some were seen at the usual hill on the fourth of this 

 month.
