INTRODUCTION vii 



The Kxpedition is under great obligation for generous assistance received from sources 

 other than that of its lamented organizer and donor, Mr. William Ziegler of New York City. 

 Mr. Ziegler was personally interested in every phase of the work and in the hope of carrying 

 out some of his last wishes the executors of his estate have published this volume. 



Acknowledgment is due Mr. William S. Champ, the rescuer of the party, whose opportune 

 arrival at Cape Dillon saved both the members and records of the Expedition. 



The National Geographic Society, through its former President, Dr. Alexander Graham 

 Bell, and its present President, Dr. Willis 1,. Moore ; its Vice-President, Henry Gannett; 

 its Secretary, O. P. Austin, and its Editor, Gilbert H. Grosvenor, and through its members 

 individually, has given encouragement and assistance in many ways, both in the initiation 

 and completion of the work of the Expedition. It was to this organization that Mr„ Ziegler 

 extended the privilege of selecting the scientific leader and it was by the unanimous action 

 of its Board of Managers that Mr. Peters was commissioned in this capacity. The scientific 

 work accomplished conforms, in general, with the suggestions made by the Research Com- 

 mittee of this Society of which Professor G. K. Gilbert was chairman. 



Grateful acknowledgments are due Professor Geelmuyden, Director of the Christiania 

 Observatory, who loaned a Repsold Circle when at the last moment it appeared that one could 

 not be obtained. 



Mr. O. H. Tittmann, Superintendent of the United States Coast and Geodetic Survey, on 

 the part of himself and the members of his Bureau, extended every possible help in the way of 

 instruction and suggestion. Through his courtesy the Expedition had also the use of the 

 instrumental outfit necessary for the execution of the magnetic work. 



Dr. L. A. Bauer, Director of the Department of Terrestrial Magnetism of the Carnegie 

 Institution of Washington, devised the plan of observation best suited to the limited instru- 

 mental outfit and conditions to be encountered, which plan experience proved successful. He 

 has further suggested the general scheme of reduction of this portion of the observations. 



Professor Willis 1,. Moore, Chief of the United States Weather Bureau, supplied a number 

 of instruments for use in the meteorological observations. 



General A. W. Greely, of the United States Army, extended assistance by many valua- 

 ble suggestions as the result of his own wide experience in Polar work ; he also arranged for 

 the loan of some meteorological instruments from the United States Signal Corps. 



The task of preparing the scientific results for publication was taken up by Mr. Peters 

 during September, 1905, upon the return of the Expedition. He was unable to complete this 

 labor personally owing to his association on January i, 1906, with the Department of Terres- 

 trial Magnetism of the Carnegie Institution of Washington as Commander of the Magnetic 

 Survey Yacht. In his absence, through the courtesy of Dr. ly. A. Bauer, Director, the burden 

 of the completion of compilation, computation, editing, and publication of the results has been 

 borne by Mr. J. A. Fleming, of the Department of Terrestrial Magnetism. The principal 

 assistance in the great amount of detail work necessary has been rendered by Messrs. E. H. 

 Bowen, C. C. Craft, W. B. Corse, and W. N. Ross.
