EXCHANGE PRICE LIST 
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.
