the mainland miich further soiith. 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° G. isotherm of Jiily) where 292 indigenoiis 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 diflerences. In the inner part of both fjords 

 the Archaean rocks are predominant and here the maintrunks of the 

 fjords are spht 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 piaces 

 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 Nugssuaq. 

 Inside Ubekendt Ejland the bay is divided into two branches, the 

 tJmånaq 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 O. Nordenskiold to include about 5.000 square kilometres. 



Climate. 



The meteorologicai records are very few and unsatisfactory. From 

 several piaces 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. Porsild (21, p. 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):
