nodules, segregated in the sand by the infiltration of some con- 

 glomerating medium, and often of remarkably regular form and 

 some yards in seetion. Atanekerdlnkstone, like the nearest 

 sands and clays always contains remains of leaves, which may 

 then either form small separate layers or an isolated nodule in

the sand, some few inches in diameter ; whereas it would be 

 vain to look for impressions of leaves in the more distant sand- 

 beds. Coal-beds worth working probably do not occur in this 

 horizon of the Miocene ; at least the layers at Atane, the largest 

 coal-beds at Kome, and at Ipiit near Kudliset, seem to belong to 

 the Upper Cretaceous, while the strata at Netluarsak, Isorisok, the 

 coal in the high fells at Skandsen and Assakak, belong to the 

 middle, not the lower, Jiorizon of the 3Iiocene of Greenland, 

 Probably also the coal-beds at Hare Island belong to the Upper 

 Cretaceous formation, as I have already observed {above, p. 430).* 



* Dr. Nauckhoff's and Dr. PfafF's discovery of Siyillaria makes it possible 

 that the Coal of the Coal-formHtion occurs at Ujarasusuk.
