PIGEONS AND ALL ABOUT THEM. 43 



birds so tender tliat a single draught or a close shipping box 

 will kill the]n. 



There are some fanciers, and they are men of brain?, who 

 predict that many of these breeds will "run out," that is, 

 they will be continuously bred up, till their young will be too 

 weak to live. 



I do not think however that such a misfortune can come to 

 the fancy for many, many years, or perhaps ever. While we 

 produce '' artilicial" birds, we also each year, learn better 

 how to care for them and we unconsciously change conditions 

 and thereby meet the changed conditions of our pets.
