great fault, the direction of which is 73° E. Along the line of this 

 fault the shales are thrown up against the conglomerates, dipping 

 from them at a high angle. This being the case, his opinion that 

 the conglomerates overlie the shales, is probably correct, and goes 

 with the description of their relations elsewhere, as given by Dr. 

 Dawson. The strata of the conglomerates are nearly horizontal, 

 while those of the shales dip southward at a high angle. 



At a short distance north of the line of fault, there is a note- 

 worthy outcrop, which seems to be the summit of an arch;. the 

 beds on the north being similar, in inverted order to those on the 

 south. At this point, the shales are very much contorted, being 

 corrugated as if by a combination of upward and lateral pressure. 

 As an example, illustrating the forces at work in producing this 

 formation, I obtained a piece of shale 15 inches in length, bent into 

 the form of a double hook, or letter S., and having that peculiar 

 " slickensided" appearance indicative of great pressure. This arch 

 has its parallel in the arched strata near the Albert Mine, which 

 are similarly contorted, and contain, like these, remains of fish of 

 the general Palaeoniscus. In fact, the general resemblance between 

 the arrangement and conformation of the strata at Belleveau and 

 Albert Mine is somewhat remarkable, especially when we take into 

 account their disturbed condition. This resemblance is such as to 

 justify the remark of Mr. Patrick that a section might be made of 

 one, which would, with very little alteration, represent the other. 

 North of this arch* in the bank of a small brook, there is exposed 

 a considerable thickness of shale. Reckoning from this point to 

 the arch, it would appear that these shales which are generally 

 regarded as the source of the Albertite. are as fully developed here 

 as at Albert Mine. 



With respect to the question of the probable occurrence of any 

 considerable quantity of Albertite in this locality, as the matter 

 will shortly be practically tested, speculation is out of place. 



Should the mining operations now in progress be successful, an 

 impetus will be given to those researches which alone can develope 

 the mineral wealth of our country ; and in the case of Albertite 

 prospecting, with largely increased chances of success.
