Another shaft was sunk in 1890, hy the Broadsound Coal Mining Company, near 
the Warerley Creek Wharf, to the depth of ninety six feet. From the bottom of the 
shaft a bore was sunk, making the total depth one hundred and twenty eight feet. At 
ninety eight feet was a coal-seam fifteen inches thick. At one hundred and twenty feet 
the following section was met with : — rt.

2. Section of strata seen in second anticline, 2G0 feet. 
3. These strata can be tested most economically by trenching.
