covering of snow and ice. The typical corries of Balglass, north of 

 Glasgow, are described, and their origin attributed partly to the preglacial 

 erosion of confluent water-falls, partly to the disruption of the wall 

 rocks during glaciation by the agency of frost and ice.

Pp. 8; 1 large topographic map showing glaciers. 

 The glaciers of Sweden are found in the high mountain area that 

 extends along the international boundary between Sweden and Nor- 

 way and in the northern part of Sweden, chiefly in the provinces of 

 Jamtland and Lappland. The most southerly glacier is found in lati- 

 tude 62 55' N. The glaciers of the north may be divided into an east 

 and a west zone, the latter including the larger and greater number of 

 glaciers. This distribution has climatic significance. There is a larger 

 snowfall north and west because of the lower temperature and larger 

 precipitation from the winds from the Atlantic. It is noted that the 

 snow line is quite rapidly lowered to the north. 



At lat. 63 N. elevation of snow line =1,355 m. 

 At lat. 66° N. elevation of snow line = 1,245 m - 

 At lat. 68?5 N. elevation of snow line = S85 m. 



Valley glaciers and plateau glaciers are distinguished; cliff glaciers are 

 subordinate. A catalogue of the various glacier districts and the more 

 important individual glaciers is given.
