INTRODUCTION. 



' ver since the closing of the Great World's Fair it has been 

 my desire to place in the hands of my ornithological breth- 

 ren and naturalists generally, a catalogue of Pennsylvania's 

 exhibit of bird's eggs, and after a delay of many 

 months I have compiled this little pamphlet as a memento of the 

 Great Exposition and at the same time give to my friends a cor- 

 rect idea of the extent of the collection, and how it was arranged 

 for exhibition. 



In preparing the manuscript for these pages I have made no 

 pretensions of fully detailing the physical features of the state 

 of Pennsylvania, nor of outlining, definitely, the various life 

 zones which effect the distribution of our birds. Upon these 

 subjects I have only touched briefly, leaving the extended de- 

 scriptions for the more comprehensive works on bird distribu- 

 tion of this region. 



For many courtesies favoring the selection of this collection 

 to represent the Avifauna of the Keystone State, bringing it so 

 prominently before the World's sight seers at Chicago, 1 am in- 

 debted to Dr. B. H. Warren, State Ornithologist, West Chester, 

 Penna., who was most active in securing the collection for the 

 use of the state, A. B. Farquhar, Executive Commissioner, John 

 A. Woodward, Deputy Executive Commissioner of the Pennsyl- 

 vania Board of World's Fair Managers, J. B. Richards, traveling 

 agent of the Board, who visited me and inspected the collection 

 prior to the final arrangements and shipment to Chicago. Also 

 Mrs. J. F. Temple, Mrs. W. G. Scott and Mrs Elizabeth Crawford, 

 local lady commissioners of Greene County. 



The plates are produced from original photographs of groups 

 of eggs in this collection and are accompanied by proper ex- 

 planations.
