Back Numbers of Bird-Lore 



T'^T'E can no longer furnish complete sets of 

 ^^ BIRD-LORE, but we still have on hand 

 odd numbers, which, while they are lacking in 

 value from the librarian's point of view, to the 

 bird student are just as useful and just as inter- 

 esting as they were on the day of publication. 



These numbers are offered at a discount of 

 50 per cent, that is, ten cents per number, to 

 purchasers of ten or more numbers. To those 

 wishing to complete their sets of BIRD-LORE, 

 we offer the free use of our advertising columns.
