The Grarrick Seam is seen in the cliff on the left bank of Pelican Creek. For 
^hout a third of this distance an intrusive sheet of “white trap” is seen cutting into the 
®eam and rendering it locally useless, but the remainder of the outcrop is undisturbed. 
The G-arrick Seam at its outcrop, and where it is not burnt by the white trap, 
shows layers of shining coal alternating with layers of dark coaly shale. It burns with 
difficulty and leaves a good deal of brown ash. The joints are coated with sulphur and 
alum. The coal is moderately firm. It takes a feeble polish under the knife, with a 
deep black lustre. The powder is lamp-black. The specific gravity is 1'456.

Near the bottom of the seam a light, feebly lustrous, non-soiling coal occurs in 
Modules of three or four inches in diameter. They burn well. It would appear that
