For my own part I readily concur with you in supposing that housedoves are 

 derived from the small blue rock-pigeon, Columba livia, for many reasons. * * * 

 But what is worth a hundred arguments is, the instance you give in Sir Roger Mostyn's 

 housedoves in Caernarvonshire; which, though tempted by plenty of food and gentle 

 treatment, can never be prevailed on to inhabit their cote for any time; but as soon as they 

 begin to breed, betake themselves to the fastnesses of Ormshead, and deposit their you ng 

 in safety amidst the inaccessible caverns and precipices of that stupendous promontory. 

 "You may drive nature out with a pitchfork, but she will always return:" 



"Naturam expellas furca * * * tamen usque recurret." 



Virgil, as a familiar occurrence, by way of simile, describes a dove haunting the 

 cavern of a rock in such engaging numbers, that I cannot refrain from quoting the 

 passage. 



"Qualis spelunca subito commota Columba, 

 Cui domus, et dulces latebroso in pumice nidi, 

 Fertul in arva volans, plausumque exterrita pennis 

 Dat tecto ingcntem, inox aere lapsa quicto, 

 Radit iter liqiiidum, celeres neque cornmovet alas." 



(Virg. Aen. v. 213-217). 



"As when a dove her rocky hold forsakes, 

 Roused, in a fright her sounding wings she shakes; 

 The cavern rings with clattering: out she flies. 

 And leaves her callow care, and cleaves the skies; 

 At first she flutters: but at length she springs 

 To smoother flight, and shoots upon her wings." 



(Dryden's Translation).
