BIRD 

 BOOKS. 



People with flexible tongues call them Orni- 

 thological publications. 



Well, I sell this class of literature, know the 

 current values of some thousand or so, and may- 

 hap can supply the unwieldy folio or frail pamphlet 

 of scanty proportions and diminutive edition that 

 you have so long been looking for. 



Correspondence promptly attended to.
