190 Notes on the Coal Field of Piciou, 



We have not been able to trace the strike of the stellar coal 

 farther west, owing to the covering of drift, which ranges from 40 

 to 50 feet in thickness between the two brooks. At 220 feet 

 from the entrance to the adit we have cut a fault running north-west 

 and south-east, which is a downthrow to the east, and is the 

 first of that kind that has been met with in the Albion coal field. 

 Its size has not yet been accurately determined, nor whether it is the 

 main fault, or only a branch that has thrown all the coal meas- 

 ures round, and made their outcrops so much farther south 

 than the general strike at the Albion Mines indicated *. 



Descending the McCulIoch Brook, but in ascending order for 

 the measures, some trial pits and boreholes have been sunk, 

 but only thick beds of fire-clay and black shales discovered ; at 15 

 chains distance from the stellar coal is the crop of a coal seam, 

 thickness not satisfactorily proved, with a band of shale full of 

 Cypris, dipping N. 20° W. At the next bend of the brook three 

 chains distant is the outcrop of beds of sandstone dip N. 22^ E. 15° ; 

 and three chains further on is a coal seam five feet or more in 

 thickness, with bands of shale intermixed dip N. 26° E. '7^°; thence 

 the distance is five chains to the old Middle River Telegraph road, 

 where there is another crop of a coal seam,which I believe to be the 

 continuation of the deep seam of the Albion Mines ; dip 12^ due 

 north, Here also the measures are disturbed by small faults, 

 and the pit is sunk on the crop, so that we cannot judge very 

 correctly of the actual thickness, or quality of the seam. Nineteen 

 feet 5 inches of coal have been sunk through, of which Mr. Eraser is 

 working the lower 7 feet 3 inches ; I have made the following 

 analyses. 



"Worked 7.3 Lepidodendron got in No. 6. Band. 



Eight chains further north is the crop of another coal seam 

 which shows in the brook for a breadth of two chains, and there- 

 fore corresponds with the main seam. Stigmarla was got in the 



* While I am writing wc have struck another fault bearing N. 8° W., 

 S. 8° E., dipping S. 82» W. 45^, being an upthrow to the east, and 

 of which the first fault is a branch. It is eight feet up as far as we 

 have gone, and we are not yet through it.
