 from a point on the lower slope of the Sentinel nunatak, looking northeasterly. The 

 smooth, nearly vertical wall of the glacier is seen in the foreground with the crevasses 

 running from left to right with an inclination forward. Crossing these in the upper part 

 of the glacier may be seen numerous lines running from left to right obliquely upwards 

 and backwards, and curving toward the glacial axis in measurable conformity to the 

 configuration of the ice. At the right hand in the foreground is seen the terminal 

 moraine mantling a base of ice, and also a portion of one of the lakelets mentioned in 

 the text. Beyond this moraine is seen the Bowdoin glacier which is separated from 

 the Tuktoo glacier by a depression and by the moraine just mentioned. The eminence 

 in the background at the left is the Sierra nunatak. The eminence in the distant 

 center is the Sugar Loaf which stands on the border of the inland ice field. The lobe 

 obscurely seen on the right is the Mirror glacier. The moraine from which Mr. Peary 

 took his departure on his last trip across the great ice field may be seen obscurely, 

 perhaps, at the right of the illustration, nearly opposite the Sugar Loaf. 



reader is invited to turn back to the figure on the page cited and 

 compare at a single glance a glacial lobe of the great ice-cap 

 and a glacial lobe of a very small ice-cap. It will be difficult to
