<on a second track back to the shore, the design being that as fa^t 

 :a« coal is required at the shipping places or shutes, the full cars 

 are allowed to run by their own gravity to the point required, 

 whence, on being emptied, they will again return by their own 

 weight to the shore, to be made up into empty trains. They are 

 switched back at the end of the wharf on to the empty or inside 

 track, running parallel to the full track, upon which they arc 

 pushed by the locomotive in coming from the colliery. This ar- , 

 rangement has, I believe, given great satisfaction, as it results in 

 a saving of the horses usually necessary for handling coal cars at 

 the shipping wharves. 



The railway and wharf were opened for traffic about the 1st of 

 October, 1868, and before the close of navigation several thousand 

 tons of coal were shipped. During the present season the colliery 

 lias been in successful operation, and a considerable quantity of 

 the coal has found a market in the provinces of Ontario and 

 (Quebec. 



In the description of the general distribution of the coal in the 

 Bear Creek synclinal it has been stated that at a few hundred 

 yards to the south of the Drummond Colliery the crop of the 

 Acadia seam comes against the West fault. The fact that the 

 crop of the seam was here lost upon a fault " with a S. W. up- 

 throw and a bearing of N. 10^ W." magnetic, (or N. 33° W. 

 astronomical) was proved and stated by Mr. Barnes. A few yards 

 to the west of the spot where the coal of the Acadia seam was 

 lost, another seam of inferior coal, about three feet in thickness, 

 was found, and beyond it, to the south-west, a second fault, with 

 a south-west upthrow was observed, bringing up red and gray 

 sandstones. These sandstones I have examined and believe to 

 belong to the Milstone grit series. 



The first fault mentioned appears to coincide in position and 

 bearing with the general run of the West fault, and, as it will 

 certainly be the western boundary of the workable coal, I have 

 in the map shown it as that fault, but it is quite possible that hero 

 the great West dislocation may turn a few yards, leaving a small 

 patch of the lower portion of the coal measures to the west of Mr. 

 Barnes' first fault, its throw being completed by the second fault 

 found by Mr. Barnes, bringing up the Millstone Grit. 



The amount of coal of the Acadia seam removed by this fault, 

 as at present understood, will be unimportant. This is known 

 from the fact that the measures overlying the scam have been
