A74 NEW SOUTH WALES. 
described section was taken, the coal bed had so lost its coaly cha- 
racter, that when first met with, I had no suspicion that a bed of coal 
existed in that vicinity. The upper part of the cliff is removed to the 
southward, and it was therefore impossible to trace out its variations 
in that direction. 
In Telegraph Hill, the south cape of the river, there are two coal 
beds visible corresponding with the third and fourth in the above 
series. ‘The following alternations were there observed, commencing 
above. 
4 feet.—Fine gray argillaceous sandstone, widening to eight feet a few rods to the north- 
ward ; lower part consisting mostly of clay. 
84 feet.—Puddingstone ; pebbles varying from one-fourth to one or two inches in size ; 
the layer has a clayey bed near its centre, which soon thins out both to right and 
left. 
15 feet.—Clayey shale; very soft below. Vegetable impressions abundant, consisting 
mostly of a species of G'lossopteris. 
6 feet.—Coal (III.) ; only the lower twenty inches are clear of clay-shale, and this part 
is worked, 
5 feet—Hard grayish-blue sandstone ; stands the weather. 
1; feet.—Grayish clayey sandstone. 
12 feet.—Fine grayish sandstone, containing some softer layers which are thin schistose. 
2 feet.—Soft clay, of a light dirt-brown colour. 
6 feet.—Coal (I1V.) and coaly shale. 
At water’s edge. 
Sandstone of a grayish-blue colour. 
This section also exhibits the inconstant character of the layers 
which alternate with the coal. 
For the following section I am indebted to Mr. James Steel, super- 
intendent of the coal works at Newcastle. It was taken down by him 
when sinking the shaft to the second or “ B” coal pit. 
17 feet.—Yellow sandstone : moderately hard, crumbling. 
15 feet 2 inches.—Soft blue stone. 
5 feet.—Coal shale, black. 
10 feet.—Soft blue stone. 
2% feet.—Bad coal. 
7 inches.—F ine white clay. 
12 inches.—Bad coal. 
20 inches.—Best coal. 
24 feet.—Soft blue stone. 
6 feet.—Hard blue stone. 
6 inches.—Soft stone. 
20 feet.—Hard blue stone, containing impressions of leaves, 
Coal bed, 5 feet 9 inches.
