The General Chart, 



scale I : 2 500 000, is compiled from the latest sources. As the charts of 

 the expedition are not yet completed, it has not been possible to make use 

 of all the topographical results of the expedition, even where the scale 

 would have allowed of their admission. 



Below are given a few items of information that have not been in- 

 cluded in the general chart, which is on too small a scale to allow of their 

 all being shown on it. They refer, it is true, to localities situated outside 

 the expedition's field of labour; but as they are of some importance to 

 the navigation of the Spitsbergen waters, they have been included. The 

 information has been obtained from Xorwegian arctic traders, mostly from 

 Captain Ingvar Svendsen, of Tromsö. The places mentioned will be 

 found on the British Admiralty chart of Spitsbergen, Xo. 2751. 



In Stor Fjord, EXE of Whales Ba}', the chart gives a dotted outline of 

 a "low flat island". Captain M. A. Johnsen, of Tromsö, informs me that 

 the Russian survey ship, the Bakan, on which he was ice pilot, tried to 

 find this shallow, and spent a whole day in sounding at the place assigned 

 to it on the chart, but found a depth of at least 50 metres everywhere.
