Below this there are four bands of carbonaceous shale ranging- from 

 one to two feet in thickness. The lowest includes about one foot of 

 poor flaky coal. Another lower seam includes about six inches of coal. In 

 the next reach the beds locally bend round by south to east, and some of 

 the carbonaceous shales are repeated. This seam, or, to speak more cor- 

 rectly, this zone of seams and carbonaceous shales, is again exposed north 

 of Rajbar, whence it follows much the same course as the bed of the 

 stream. By intei-polation it has here so increased in dimensions that it 

 is nearly a mile wide south of Kolherwan.
