found, which cannot cause any great deposition of clay on the 

 coast-ice, and something Ihe same will probably be the case 

 with the glacier-ice. Consequently we may suppose that only 

 the especially-developed right part of the curve has its origin 

 in ice-transport, and that by far the greater part of the 

 material originates from the coast erosion. This curve, as also 

 many of the others, must only be considered as a somewhat 

 imperfect representation of the sea-floor, as all the larger stony 

 ingredients are entirely absent, and these must necessarily have 

 occurred here in great quantities, as so many of them have 

 been observed on the icebergs. With regard to this sample, 

 we are thus better able than in any of the others to determine, 

 by direct observation, that the coarser ingredients must have 

 been deposited in very great quantities from a geological point 

 of view ; moreover as an examination of the sample shows that 

 a comparatively considerable amount of finer ingredients is 

 deposited, we may conclude that the coast erosion, and the 

 thereby-ensuing transport of material, must also take place with 

 great force inside the bay. As the deposition takes place 

 comparatively quickly, it can scarcely be supposed that any 

 material of the sea-floor can have originated from the forma- 

 tions of the ice-age. 



The three last samples No. 43, 45 and 46, have a quite 

 different appearance, but they were obtained from smaller, 

 shut-in bays, where no icebergs, or hardly any, ever came 

 and where the current must have been rather slight. All three 

 samples are of the very finest description, as they contain only 

 very little sandy or stony material. The absence of the last- 

 named material must be due to several concurrent causes. In 

 the first place no ice-masses, or hardly any, come into the bays 

 from without, otherwise greater quantities of stony material 

 would have been conveyed hither, especially in the case of those 

 currents coming from Score shy Sund. Moreover special cir- 

 cumstances must be called into play with regard to the ice
