To the rise of this borehole is the outcrop of the main seam on 

 which a Jiumber of shallow pits have been put down ; among 

 them the McLeod pit mentioned on page 50 of the Survey report, 

 in which an 8 feet seam was got, but of the coal only 2 feet 6 

 inches was good. The seam was also opened on a small brook 

 about half a mile to the south, and found to have very much the 

 same section ; and again on the north flank of Weaver's mountain 

 a coarse coal dipping N. E. was opened by Mr. A. McBean, and 

 believed to be the same seam. 



The Deep and other underlying seams have not been traced so 

 far, and it is thought they sooner lose their coal than the Main 

 seam. Both in the Crushed mines and the Foord pit the east levels 

 were when stopped in coal of a greyish cast and thinner, so that 

 it is evident the influence that deteriorated the seams east of the 

 river extended for some distance in towards the centre of the 

 valley. Whether it left from the centre northward, and possibly
