EXCHANGE PRICE LIST 97 



BIRDS EGGS FOR EXCHANGE 



I have the largest list of duplicate eggs for 

 exchange in North America. 



I have sources of supply UNEQUALED by 

 any other collector in North America. 



For Rare Specimens my opportunities are 

 GREATER than any other Oologist in North 

 America. 



My Private Collection is the LARGEST col- 

 lection of North American Eggs, outside of 

 the U. S. National Museum, in the World. 



I am always in the market, to buy or ex- 

 change, for specimans of Eggs or Skins of 

 Birds desired by me, and am willing to give 

 the highest price in Cash or the best exchange 

 for what I want.
