THE OOLOGIST 



(Of Albion, N. Y ) 



IS THE OLDEST PUBLICATION IN AMERICA. 



The OiKJXiiST is thecheapr^st "Bird" publication 

 in the world (for only 50 cents you receive SI. 00 

 worth of premiums, your selectitii, 25c. worth of 

 advertising and the Oologist for a whole year). 



The Oulogist, has a larger paid circulation than, 

 all other "Bird" publications in America combined. 



The Oulogist has long been recognized the best 

 Advertising Meilium in its line in the world. The 

 ^^Country Gentlemen^' is the leading .Agricultural 

 newspaper in America, and in soliciting atlvertising 

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

 }owinig 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 

 the Country Gentlemen among agricultural publi- 

 cations. 



The Oulogist has very few halftones and contains 

 only 16 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. Th^ 

 Oologist, however, is still issued each month and 

 a sample copy of a recent issue can always be 

 obtained by addressing a postal to
