 respect his incognito. 



Next morning, on accompanying him to his mine, we 

 were surprised to find an open exposure of a seam of 

 excellent coal, 10 feet in thickness and dipping to the 

 north-west almost at right angles to the direction of 

 dip of the measures farther down-stream (Plate VI.). 



At the fork there were clear exposures of beds 

 dipping south-west, so there must clearly be a dis- 

 turbance between that point and the outcrop of the 

 seam. It was impossible to follow the section down- 

 stream on foot as the river entered a gorge cut in a

hard sandstone, and the water occupied this from side 

 to side. 



We therefore returned to the " Hermitage," as we 

 had christened the place, and thence to the canoes. On 

 paddling up-stream we entered the gorge from its lower 

 end and found ourselves between walls of shale whose 

 beds appeared almost horizontal, again a strike section, 

 and then we suddenly came upon a fault which brought 

 in the sandstone with a strong dip to the north-west 

 (Fig. 22). 



The dip rapidly diminished as we passed up-stream 

 until, on reaching the Hermit's mine, it had fallen
