crest of a high mountainous coast, and a "domed glacier" in 
Inglefield gulf, having the form of a great roundly sloping al- 
luvial fan, with its border broken off in steep cliffs by the 
sea. Prof. Heilprin ventures the opinion that exploration and 
study of the Greenland glaciers will probably bring "no ex- 
planations that have not already been made familiar through 
the teachings of other countries." Glacialists, however, will 
be more hopeful, since our literature and resources for theo- 
ries have been so increased by Russell's studies, in 1890 and 
1891, of the Malaspina glacier or ice-sheet in Alaska. Much 
new light is expected, by investigators of the glacial drift and 
its problems, from the past summer's observations of the 
Greenland ice-sheet and glaciers by Chamberlin and Wright, 
supplementing the previous observations of Rink, Hoist, 
Steenstrup, Nftrdenskiold, Nansen, Peary, and others. 
Furthermore, it is to be earnestly desired that an expedi- 
tion on the Antartic ice-sheet shall be undertaken, and it 
seems possible that a great part or perhaps nearly all of the 
distance of 850 miles from the shore near the high volcanoes 
Terror and Erebus to the pole can be traversed, with a safe 
return, during the three months of the circumpolar midsum- 
mer available for such an expedition. It would be very in- 
structive to learn whether the maximum central altitude of 
the ice surface in Greenland, about 9,000 feet where it has 
been crossed b} r Nansen and Peary, is exceeded by the far more 
extensive Antarctic polar ice-cap. Nunataks, or the tops of 
hills and mountains projecting above the ice-sheet, are found 
in Greenland only near its borders ; but the Antarctic conti- 
nent, while having chiefly a low margin, may contain very 
high mountains, rising out of the ice as nunataks far toward 
the south pole. w. u.
