BIRDS EGGS 



FOR EXCHANGE 



An Unusual Opportunity 



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

 sired by me. two hundred and eighty different varieties of 

 birds eggs. Of some species 1 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 1 will send you 

 my list in reply. 



Some specimens that 1 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 specimens 

 or to enlarge series in your collection.
