*The studies upon which this papor is based were carried on by the 
Cornell party, which accompanied the Peary expedition in the summer 
of 1896, and spent a month on the Upper Nugsuak peninsula, in Lat. 
74 deg., 10 to 1.5 min. Aside from the writer, the members of this 
party were professor A. C. Gill and Messrs. T. L. Watson, J. A. Bon- 
steel, E. M. Kindle, and J. O. Martin . To all of these I am greatly in- 
debted for aid in the work, and I wish also to express my indebtedness 
to Lieut. Peary and also to Mr. E. G. Wyckoff who furnished the money 
for the expedition.
