cleared out to expose the coal, and has, doubtless, long since been filled up 

 again. 



Five yards lower down stream there is a fifth seam, the section of 

 which is as follows :—

The first is so interbanded with shale that it can scarcely be consid- 

 ered workable, so that the known available thickness of coal in the 

 Disang is about 30 feet. The upper four seams have all been quarried 

 on a small scale ; the third and fourth on both sides of the stream.
