THE OOLOGIST 



iof Albion, N. Y. i 



1S THE OLDEST PUBLICATION IN AMERICA. 



Tmjc Oolog.st is the cheapest "Bird" publication 

 in the world (for only 50 cents you receive $1.00 

 worth of premiums, your selectk i, 25c. worth of 

 advertising and the Oologist for a whole year). 



The Oologist, has a larger paid circulation than, 

 all other "Bird'' publications in America combined. 



The Oologist has long been recognized the best 

 Advertising Medium in its line in the world.. The 

 "Country Gentlemen" is the leading Agricultural 

 newspaper in America, and in soliciting advertising 

 for its columns, it makes its strongest hit in the fol- 

 lowing statement: "As to quantity of circulation it 

 publishes many more 'Want Ads' than all other 

 papers combined. You doubtless know what a 

 'Want Ad' circulation must be and always is?" 



From this same stand point The Oologist's rank 

 among publications devoted not only to Ornithology 

 but Natural History as well, is identical to that of 

 'he Country Gentlemen among agricultural publi- 

 cations. 



The Oologist has very few half-tones and contains 

 only 10 pages each issue— one- half of which are ad. 

 vertisning. 



During the past fifteen years, (The Oologist's 

 age) many superior "bird" publications and scores 

 of inferior ones have dropped by the way. The 

 Oologist, however, is still issued each month and 

 a sample copy of a recent isMie can always be 

 obtained by addressing a pi slal to
