DELAWARE VALLEY ORNITHOLOGICAL CLUB. 7 



clusively a naturalist of the woods, and in fact the greatest de- 

 gree of accomplishment that can be acquired in this line entitles 

 one to but a very humble rank as a cultivator of Zoology. 

 There must be a combination of theoretical and practical ac- 

 quirements and the gratification of the practical naturaUst, or the 

 collector will be exactly in proportion to his scientific or system- 

 atic information to be obtained only in the museum and the 

 library. Great is life in the woods, say we, and the greatest of 

 all sports is bird collecting; but to become a scientific ornitholo- 

 gist is quite another business, and a very much more consider- 

 able consummation." That John Cassin reached this "con- 

 summation" there is no question, and among those who have 

 contributed to the development of the science of ornithology his 

 name must be included in the foremost rank.
