QUEEN CHARLOTTE ISLANDS. 77 B 



On reviewing - the appearance presented by the seams, it would Economievalne 

 appear that too great dependence has been placed on their continuity l ede|, "-' t - 

 and uniformity, without the necessary amount of preliminary explor- 

 ation to determine these points. The indications were not such as to 

 justify a heavy expenditure in preparing for the shipment of coal, but 

 quite sufficiently promising to render a very careful and systematic 

 examination of the locality desirable. This yet remains to be accom- 

 plished, not necessarily by expensive underground work, but preferably 

 by the tracing and examination by costeening pits or otherwise of the 

 whole length of the outcrop of the coal-bearing horizon. 



It is, however, evident that the knowledge of this region so far 

 obtained affords no ground for the belief that it is equally important as 

 a coal-bearing district with Nanaimo or Comox, on Vancouver Island, 

 where the conditions suitable to the formation of coal have occurred 

 not only over wide areas, but at several distinct horizons in the 

 Cretaceous rocks. 



Camshewa Inlet and Coast betioeen Skidegate and Cumsheica. 



Between Skidegate and Cumshewa the coast being low, exposures Agglomerates 

 are infrequent. The rocks seen are agglomerates and tufaceous sand- s£ndsta^s 0US 

 stones generally highly felspathic, and associated with some massive 

 felspathic materials of uncertian origin. These rocks on the whole 

 resemble pretty closely those of Subdivision D. of the Skidegate section, 

 to which they may belong. Under the supposition that they represent 

 this part of the series, and that if softer ordinary sedimentary beds 

 underlie the coast line the}- have been worn away and concealed, the 

 whole has been coloured — though still with some doubt — as belonging 

 to the Cretaceous. 



The northern entrance point of Cumshewa Inlet is composed of in-Dioriticg?umte 

 trusive rock, cheifly diorite and dioritic granite, but the greater part 

 of the shores of the inlet are formed of rocks of the Cretaceous series. 

 The Skidegate section having been described in some detail, it will be 

 unnecessary to refer to these in other than brief terms, though the sub- 

 division adopted for Skidegate cannot here be strictly carried out. 



Between McKay's Cove and the Cumshewa Indian village, aud on the Agglomerates 

 little island near the village, the rocks are agglomerates and tufaceous 

 sandstones of dark colour. They are hard and traversed by dioritic 

 dykes in a few places. On the island, though well bedded, the rocks 

 from their fine grain might well be mistaken for diorites. A few 

 bundred j^ards east of the Indian village, many small veins traverse 

 the agglomerate rocks, and contain iron pyrites and galena in about Lead, 

 equal proportion. One vein about eighteen inches wide was noticed,
