GEOLOGIOAL CONFORMATIONS. 461 



On the 20tli May (17.5° Fahr.) we began our return 

 march, the deserted camp forming as usual a deep hole in 

 the snow. 



On the 21st (10° Fahr.) we reached the middle of a 

 segmental projection on the east side of Kuhn Island 

 which rose in undulations to a height of 1020 feet. 

 This projection consisted of layers of slaty sandstone 

 and marl, the petrifactions showing that this deposit 

 was of the secondary formation, lying like a cloak on 

 the westerly rising of crystalline stone. The surface of 

 this formation was covered with an erratic covering of 

 rubbish of the last-named stone. 



On the 22nd and 23rd we explored the individual strata 

 of the formation ; they showed a perfect agreement with 

 those on the south side of Kuhn Island, a westerly incline 

 of 7°, coal clay, petrifactions (Inocerames, Ammonites, 

 Belemnites, &c.), bluish-grey fuller's clay, thin stratas of 

 marl, and rather coarse-grained granite alternated with 

 each other. 



Coal-beds were nowhere to be seen. But about under 

 the summit of the " black wall " we found some sandstone 

 and small pieces of coal. 



Several masses of dolerite ran horizontally through the 

 upper bank of the sedimentary layers. 



Hochstetter's Promontory bore the same geological 

 character, so that both these spots possibly belong to the 

 later secondary sedimentary rocks, only interrupted by 

 the sinking of Ardencaple Inlet. 



Much damage did our stay here cause amongst a herd 

 of musk-oxen. On the 21st Tramnitz shot a cow; on the 

 22nd Wagner surprised the whole herd while sleeping, 

 and killed a bull ; and on the following day another fell
