In the next reacli the above beds, modified in character and relative 

 thickness, are again seen. The coaly portions, which are better ex- 

 posed, are in mere strings. 



In the reach again next following there is further modification. No. 4, 

 is reduced to about 4' 6*, and consists chiefly of blue shales and coal, 

 alternating every 3 or 4 inches.

In next reach we find the junction with the Borasukwa stream 

 where Nos. 1 and 2 are repeated. No. 1 being thicker and more varied in 

 character, including massive sandstones and thin layers of carbonaceous 

 shale^ and No. 3 slightly more coaly, dip 10° to 30° west of north. 



In the reach next beyond the junction these shales include one band 

 of coal 1' 6" f besides this there are several thinner seams with varying 

 thickness of coal.
