APPENDIX I 



IN the agreement between Mr. Leffingwell and myself, an arrangement 

 was made providing for the distribution of our work both while the expedi- 

 tion was in progress and after our return. Mr. Leffingwell was to have 

 charge of the scientific work, as well on the expedition as after our home- 

 coming ; hence the task of summarizing the scientific results of the expe- 

 dition in an appendix belongs properly to him, but owing to circumstances 

 detailed in the narrative he remained on Flaxman Island to finish his sur- 

 veys of the coast, of the numerous rivers, and of the mountain range, hitherto 

 unexplored. He also proposed to devote some time to studying the geology 

 of the country. 



As we had not foreseen the possibility of my return alone, I feel that I can 

 do no more than give a very brief statement of the work we have done, and 

 refer readers who desire further information to the scientific results, which 

 will be worked out and published by Mr. Leffingwell upon his return. 



Immediately on our arrival at winter quarters, meteorological observations 

 were begun and continued without interruption until the time when the crew 

 left Flaxman Island. Mr. Storkersen made these observations, and while he 

 was absent on sledge trips they were taken by Hicky. 



Our record of tide observations is highly valuable. We commenced to take 

 them in earnest as soon as the sea ice was sufficiently solid to bear our weight 

 (September 16). Direct readings were made for every hour, and for every 

 ten minutes from forty minutes before to forty minutes after the turn of the 

 tide. The readings at the station on Flaxman Island were continued without 

 interruption to January I, 1907. Besides the observations made at Flaxman 

 Island, others were made at Icy Point (120 miles to the east) and at Pole 

 Island, some little distance to the west. 



These records were too heavy for me to carry on the sledge on my home- 

 ward journey, and the numerous observations will not be worked out until 

 the return of Mr. Leffingwell. 



During the winter the absolute latitude and longitude of Flaxman Island 

 were determined by Mr. Leffingwell, but magnetic observations were not 

 taken, as we could not afford the expensive instruments. 



My contribution to the scientific work of the expedition is the investiga- 

 tions carried on during our sledge trips over Beaufort Sea. Soundings and 

 discussions on the drift will be found in the two chapters describing the 

 sledge trips, but I' will here summarize the results. 



Although such scientists as Dr. Nansen and Dr. Spencer had suspected 

 that the Continental Shelf was very narrow to the north of Alaska, we thought 

 we had well-founded proof that it was considerably broader than they
