the mainland much further south. The flora-belt 69°—71°, including 
Disko, with its 252 species is only surpassed in richness by the flora 
of the southernmost part of Greenland between 60°— 62° (reached by 
the 10° C. isotherm of July) where 292 indigenous species are recorded. 
The flora of the Nordost Bugt seems to me the most appropriate 
to compare with that of Scoresby Sound on the East Coast. The latitude 
` of these two districts is almost the same; Nordostbugt 70°20’—72°25’ 
and Scoresby Sound 70°—71°50’, and even in the geographical features 
there are no very striking differences. In the inner part of both fjords 
the Archaean rocks are predominant and here the maintrunks of the 
fjords are split up into numerous tributaries, penetrating deep into the 
inland ice and uniting inland to form a system of sheltered channels 
through an archipelago of more or less tabular block-islands. Near the 
coast on both sides of Greenland the Archaean rock in several places 
are succeeded by sediments which are usually covered by a considerable 
thickness of basalt. 
From the inland ice numerous glaciers discharge into the fjords 
where, consequently, icebergs and fragments of icebergs are always 
plentiful. 
The general direction of Scoresby Sound is E—W and it penetrates 
abt. 300 km. inland and is thus almost twice as long as Sognefjorden 
in Norway, the longest fjord in Europe. The entrance of the Nordost 
Bugt is much wider: The name Nordost Bugt is applied to the region 
which lies between the two peninsulas Svartenhuk and Nügssuaq. 
Inside Ubekendt Ejland the bay ıs divided into two branches, the 
Umanag Fj. NW—SE and the Karrat Fj. SW—NE. The former pene- 
trates rather more than 150 km. inland. The ice-free land has been 
estimated to include about 12.000 square kilometres, while Scoresby 
Sound includes a rather larger area; Jameson Land alone has been 
estimated by О. NORDENSKIÖLD to include about 5.000 square kilometres. 
Climate. 
The meteorological records are very few and unsatisfactory. From 
several places in the Nordost Bugt however series of meteorological 
observations have been published in the annual reports of the Danish 
Meteorological Institute. They are rather incomplete but by comparing 
them to the long and excellent Jakobshavn series, PorsiLp (21, р. 356) 
has shown that the temperature is lower during winter while at least 
in the inner parts of the fjords the temperature of July may even be 
higher than at Jacobshavn. The mean monthly temperatures of Jacobs- 
havn during 22 years are as follows (33):
