THE OOLOGIST 



The July number of The Oologist will 

 contain Frank L. Burns' Bibliography of 

 scarce or out of print North American 

 Amateur and Trade Periodicals devoted 

 more or less to ornithology. 



This has taken more than two years 

 to produce and is a monumental effort 

 on the subject. It will be invaluable as 

 for reference and as a checking list in the 

 futuer and only a limited number of 

 copies have been printed. If you want 

 extra copies send in your order; other- 

 wise it may be too late. Price 25' cents.
