THE AMERICAN MUSEUM OF NATURAL HISTORY, through the issue 

 of this brochure, endeavors to acknowledge the generosity of those whose 

 liberal contributions have made it possible for Mr. Andrew J. Stone to 

 attack the zoological problems of the Northwest. It desires to make known more 

 generally the scientific results that have attended Mr. Stone's efforts, and it 

 hopes that the example herein set forth of achievements gained through a com- 

 bination of men ready to help, with a man ready to do, may result in the organi- 

 zation of other expeditions to other lands.
