Iceland, according to the climatic conditions, may he divided 

 into 5 districts, which division, also as regards the Land vegetation, 

 coincides well with that employed by Helgi Jonsson (1912, p. 5) 

 for the Marine vegetation along the coasts. 



East Iceland, from Eystri Horn in the South-east to Langa- 

 nes in the North east. 



North Iceland, from Langanes to Cape Horn in the North- 

 west. 



North-west Iceland, from Cape Horn to Latrabjarg. 



West Iceland, from Latrabjarg to Reykjanes. 



South Iceland, from the western point of the peninsula of 

 Reykjanes to Eystri Horn. 



The boundary lines between these districts are in most places 

 formed by ridges or high-lying mountain plateaus. In the South- 

 east, Lonsheidi (height about 400 metres) and Hofsjokul form the 

 boundary between South and East Iceland. West Iceland is sepa- 

 rated from South Iceland by the mountain-chain which stretches 



/ 



throughout the peninsula of Reykjanes, the lofty mountain of Hengill, 

 the lake of Thingvalla and the mountains situated north of a line 

 drawn from Thingvellir to Geysir. Between North and East Iceland 

 there is no sharp boundary line, either as regards climate or geo- 

 graphy. South-east Iceland (from Seydisfjordur southwards) has a 

 very damp climate with many foggy days (near Berufjordur on an 

 average 171 annually), while the western part of North Iceland (the 

 districts about Eyjafjordur, Skagafjordur and Hunafloi) has a greater 

 difference between the summer and the winter temperature, con- 

 siderably less precipitation and comparatively few foggy days. North- 

 west Iceland, which comprises the country around the deep, narrow
