On Mill Creek, about four miles above the mill, a seam of 

 coal outcrops. The measures are somewhat broken, and the 

 seam appears to be rather inconstmt in thickness. It was in- 

 tended last autumn to make a careful examination of this neigh- 

 borhood, and to endeavour to follow the coal-bearina' horizon 

 southward and north-ward from Mill Creek to its outcrop on 

 other streams, but this was prevented by the the early onset of 

 wintry weather. The coal is of excellent quality, and yields a 

 firm coke. It has been used to a small extent in blacksmith- 

 work at the mill. The following are sections of the seam on 

 opposite sides of a break or fault which traverses the measures at 

 the outcrop : —
