DISTRIBUTION OF ICE 615 



They were larger at the north and smaller at the south. Of gla- 

 ciation in the mountains of Mexico little is known. 



Greenland was glaciated more extensively than now. Newfound- 

 land seems to have had its own ice-sheet, and the same was probably 

 true of Nova Scotia, and probably of the peninsula between the Bay 

 of Fundy and the lower St. Lawrence. 



Other continents. South of the ice-sheet of Europe (Fig. 505), 

 great glaciers descended from the Alps to the lowlands in all direc-

tions. Iceland was buried in ice, and even Corsica had glaciers. 

 In Asia glaciers larger than those of to-day affected all the higher 

 mountains, and ice-sheets existed in some of the more northern 

 lands. In tropical regions, there were glaciers in mountains where 

 none exist now, and in mountains where there are glaciers now, the 

 ice descended to levels 5,000 feet or more below its present limits. 

 The southern hemisphere was affected less than the northern, but 

 the higher mountains generally bore glaciers, and even mountains 

 which were not very high, as the southern Andes, had glaciers which
