BIRD SKINS. 



Don't pay dealers prices, but buy 

 directh' from tlie collector. 



TO EEO-IItTiTEI^S. 



I have made arrangements to sell 

 the following collections of skins, 

 made up first class, with full data of 

 collection, at the following rates : 

 Collection of lo species - S^-S^^ 

 Collection of 25 species - - 4.50 

 Collection of 50 species - 10.00 

 Collection of 100 species - 35. 00 



A trial order will convince you that 

 I will do just what I say. The 

 ki-ndred study of Oology cannot be 

 properly studied without the bird 

 skins. Remit by registered letter, 

 and deduct cosi of same from order. 

 Now is the time to start a collection.
