but found to run out rapidly in both directions. These volcanic rocks 

 are supposed to represent those of Subdivision D. of Skidegate. 



In following the north shore of the inlet, a gap of about a mile now 

 occurs in the section, beyond which the rocks are frequently seen, and

inlet. rp ^ Q vicinity- of Conglomerate Point they appear to represent the 



lower shales and sandstones, or Subdivision C. of the Skidegate section. 

 Their general dip is southward, and they lie as a rule at an angle of 

 about twenty degrees, though in several places they are nearly hori- 

 zontal, or slightly undulating, over considerable areas, and occasionally 

 become quite vertical, Owing to the close general correspondence of 

 the direction of the shore with their strike, and irregularities in the 

 rocks themselves ; it was found impossible to arrive at a satisfactory 

 estimate of the thickness of the entire series, though a measurement 

 was carried out with this object. It may be stated, however, that this 

 thickness is probably not less than 2000 feet, and may be much more. 



In their general character the rocks resemble pretty closely those of 

 the same part of the series in Skidegate, but sandstones are here less 

 important, and arenaceous shales more largely represented. Many layers 

 are nodular, and in some cases highly fossiliferous, though each nodule 

 . does not invariably contain a fossil. In some beds the nodules become 

 large pale lenticular masses of limestone, like those frequently found 

 in Skidegate. 



Section in the A short distance east of the Peninsula pale yellowish grits, 

 which are supposed to be the base of Subdivision C, are seen. 

 They form a small anticlinal, as shown in Figure 6, and to 

 the south-west are overlain by dark argillites, in some places 

 concretionary and fossiliferous. These appear to be interleaved 

 with one important, and perhaps one or more minor sheets of volcanic 

 rock, which seems to be contemporaneous in origin. At the extremity of 

 the Peninsula the argillites are seen in wide exposures between high and 

 low-water marks, and appear to be folded in a rather sharp synclinal, 

 though this may be a local disturbance not profoundly affecting the 

 rocks. According to the view taken of it, the thickness of strata shown 

 between the grits and highest argillites, is either 800 or 1200 feet. 



Fossiliferous A mile and a quarter west of the Peninsula, is situated the locality in 

 which fossils were found most abundantly. Half a mile further on, a 

 green basic volcanic rock forms a low cliff along the shore. It is 

 associated with sandstones, and has an appearance of being stratified, 

 which is probably, however, in this instance fallacious, as the rock 

 seems to be a diorite, and the strata near it are confused.
