BIRDS EGGS 



FOR EXCHANGE 



An Unusual Opportunity 



I have on hand, to offer for exchange for specimens de- 

 sired by me. three hundred and one different varieties of 

 birds eggs. Of some species I have but one set, of others 

 considerable series. Send me a list of what you have for 

 exchange and if it contains anything 1 want I will send you 

 my list in reply. 



Some specimens that I have for exchange are very rare 

 and hard to get, and others are of the comm(»n varieties. 



This is an unusual opportunity to secure new speciment> 

 or to enlarge series in your collection.
