From the earlier belief that the Greenland and American ice-sheets 

 were united during the Glacial period there has of late been a reaction, 

 and the pendulum has swung so far in the opposite direction that it is

* In making this study I am greatly indebted to all of my colleagues of the Cornell party, which 

 besides myself was composed of the following : Professor A. C. Gill and Messrs J. A. Bonsteel, 

 T. I,. Watson, J. O. Martin, and E. M. Kindle. Each one rendered me much aid in obtaining 

 facts, making suggestions, and in discussing conclusions. I wish also to express my indebtedness 

 to Lieutenant Peary for the opportunity to make the study, as well as for the admirable way in 

 which he carried out the plans which he laid before me. Above all, the party is indebted to 

 Mr E. G. Wyckoff, of Ithaca, New York, who furnished the money for the expedition, without 

 which the investigations would not have been possible.
