Back Numbers of Bird- Lore 



WE can no longer furnish complete sets of 

 BIRD-LORE, but we still have on hand 

 odd numbers, prior to the current volume, which, 

 while they are lacking in value from the libra- 

 rian's point of view, to the bird student are just 

 as useful and just as interesting 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.
