70 THE CANADIAN NATURALIST. [Vol. vi. 



traced along tlie east side of the fault, and as they dip at very- 

 low angles, it is probable that only some 70 or 100 yards of coal 

 next the crop will be cut off by the fault. No reason is at pre- 

 sent known why the second levels from the Drummond colliery 

 should not run around regularly to the south-eastern portion of 

 the area. 



SUTHERLAND AREA. 



But little work has been done upon this area, and no coal has 

 as yet been opened. It will be seen that the north fault runs 

 diagonally through it, cutting it into two portions. To the south 

 of this fault the area is probably underlaid with the lower seams 

 or a portion of them. The Montreal and Pictou seam, and any 

 seams which may be found above it, will, if no dislocation exist, 

 turn to a westerly dip upon this area, and at a few chains from 

 the east line their crops will come against the fault. 



The coal in this area might, perhaps, be successfully worked in 

 connection with the Montreal and Pictou area, and a small por- 

 tion of the northern part of the area of the General Mining Asso- 

 ciation." 



The report on the quality and economic value of the coals is 

 most exhaustive and elaborate, but does not afford material for 

 extracts. 



Sir William Logan, late Director of the Survey, gives the re- 

 sults of a detailed survey of the difficult and broken coal district 

 lying to the eastward of the East River of Pictou, the complexi- 

 ties of which he has to a great extent unravelled, and has illus- 

 trated by an excellent map, which very well illustrates the limits 

 of the coal as at present ascertained, and the values of the respec- 

 tive coal properties. Much, however, still remains to be done ; 

 and it is to be hoped that the work so well begun by Sir William 

 and Mr. Hartley will be efficiently followed up. 



Dr. Hunt's portion of the Report is replete with scientific and 

 practical information. The geological relations of the Salt Region 

 are thus described : 



THE GODERICH SALT REGION. 



'' In the Report which I had the honor to submit to you in 1866, 

 there will be found, on pages 263-272, an account of the salt 

 deposit then recently discovered by boring, at a depth of 1,000
