Report on the Danmark expedition to tlie north-east coast. 143 



ing evenly into the fast land ice, in which the distinct influence of 

 tidal motion could be seen. The land-ice lay unbroken between the 

 islands from the largest of the Norske Islands to the Franske Islands 

 and from here out to the north end of He de France, down along the 

 west side of this island to its S.W. point. From this place the fast 

 land-ice turned to the west, then to the south along the land south 

 of Cape Marie Valdemar. 



Along the eastern side of lie de France there ллеге many new- 

 ice formations bounded in the far distance by a broad belt of screw- 

 ice. On the southern side of the island there was new ice and open 

 water. 



In spite of repeated obserл'ations Bistrup found no trace of any 

 movement in the sea-ice. 



3e. Return journey of G. Thostrup and Wegener. 



In the evening of April 22nd the 1st and 2nd parties with G. 

 Thostrup and Wegener started for the north while Bistrup and 

 Ring remained at Mallemukfjæld, being the first party to return home 

 according to Mylius-Erichsen's plan for the great sledge journey. 



The next party to turn back, in accordance with the plan, was 

 G. Thostrup and Wegener (see p. 119). 



During the return journey G. Thostrup was to supplement Koch's 

 surveys made on the journey up with others, especially from the coast 

 of the mainland, while Wegener should continue his physical investiga- 

 tions. 



On April 26th the depot at 80°43' (Amdrups Landj was laid out 

 and on the same day at 10 p. m. the 1st and 2nd parties separated 

 from G. Thostrup and Wegener and proceeded further northwards. 



Wegener had given his good sledge in exchange for Bertelsen's 

 bad one and a good dog to Hagen instead of one of his poorest ones. 

 G. Thostrup had besides given a dog to Koch. 



April 27th. After making some survey observations at the tent- 

 place G. Thostrup and Wegener at 10.30 a. m. drove out to Henrik 

 Kröyers Islets in order to investigate these skerries, which are only 

 20 meters high. The ice between the land and the rocks was quite 

 smooth as far as 2 kilometers from the skerries, where it was screwed. 

 East of the rocks there was a belt of screw-ice about 1 kilometer broad, 

 outside this a belt of open water extending north and south and widen- 

 ing out in a northerly direction. Outside the open water they saw 

 screw-ice as far as the eye could reach. 



On the islands as well as on the land itself they found numerous 

 fossils. 



On April 28th they began the return journey, driving S.W. along 

 Amdrups Land, afterwards advancing into the Ingolfs Fjord. 



On April 29th the tent was pitched on the northern side of the
