BIRD SKINS. 



Don't pay dealers prices, but buy 

 directly from the collector. 



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 - $i-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 

 kindred study of Oology cannot be 

 properly studied without the bird 

 skins. Remit by registered letter, 

 and deduct same from order. Now 

 is the time to start a collection.
