that they sometimes breed in that county. 

 But why did not your correspondent de- 

 termine the place of its nidification, whe- 

 ther on rocks, cliffs, or trees ? If he was 

 not an adroit ornithologist I should doubt 

 the fact, because people with us perpe- 

 tually confound the stock-dove with the 

 riiisr-dovc. 



For my own part, I readily concur with 

 you in supposing that house-doves are 

 derived from the small blue rock-jngeon, for 

 many reasons. In the first place the wild 

 stock-dove is manifestly larger than the 

 common house-dove, against the usual rule
