THE OOLOGIST 



(of Albion, N. Y.) 



IS THE OLDEST PUBLICATION IN AMERICA. 

 The Oologist is theeheapest "Bird" publication 

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

 worth of premiums, your selectica, 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 O.ii.ocim has lung 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- 

 [owinig statement: "As to quantity of circulation it 

 publishes many more 'Want Ads' than all oth r 

 papers combined. You doubtless know what a 

 'Want Ad' circulation must be and always isV 



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 Oologist has veryfew half-tones 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. The 

 Oologist, however, is still issued each month and 

 a sample copy of a recent issue can always be 

 obtained by addressing a pcstal to
