“ The strata are nearly horizontal, having a very slight dip to the south-west. 
“ Following down the gully three-quarters of a mile, there are several small seams 
in the bottom of the watercourse, and on the southern bank a seam of coal eight feet 
thick is exposed. 
“ On the bank of the river, three-quarters of a mile east of the shaft, there is a 
seam of coal, one and a-half feet thick, at the water level. 
“ Taking into consideration the relative positions of the outcrop of these seams, it 
may he inferred that the coal in Mr. Lyons’ shaft is the uppermost bed, and that there 
is a small seam some fifty feet lower, and a thick workable seam a hundred feet deeper, 
a portion of which, being thrown up by a fault, was worked at the old Moggill Mine. 
“ The coal is bituminous, moderately hard, cakes a little in coking. Specific

“ Goodna Mine. — Crossing the Brisbane Hiver, some thin bands of inferior coal 
are visible under the sandstone of Mr. Jeay’s quarry, just below Woogaroo; and at 
Goodna a seam of coal crops out, less than a mile from the river. 
“ This seam, which dips from 3° to 5° to the southward, was originally 
worked from the outcrop, but now by a shaft ninety feet deep, through sand- 
stone and inferior bands of coal, the workable portion being about four and a-half feet 
thick. This mine has been extensively worked for about eight years, and has furnished 
a large proportion of the coal supplied to the steamers on the river and intercolonial 
traffic. 
“ The coal is of fair quality, with bright laminar fracture, but rather tender and 
friable. It cokes well. Specific quality, 1'47.

“This seam of coal is apparently limited on the east by Woogaroo Creek, and on 
the west by a fault and Kedbank Creek, beyond which it again aj^pears in the old 
Bedbank Coal Mine, extending up the Hiver about a mile and a-half to the Six-mile 
Creek, in which direction it deteriorates both in quality and thickness. 
Bedhanh Coal Mine. — The Bedbank coal-seam, though now abandoned, for 
several years was the chief source of supply in the district. It is nearly horizontal, 
the di]3 a little to the south, the thickness varying from three to six feet, with several 
bands of shale. The outcrop extends for half a mile along the bank of the river. The 
coal is rather soft, and very similar to the Goodna seam, but not so free from shale and 
band.* 
“ Six-Mile Creek. — At the Six-mile Creek, on the Ipswich Boad, there is a disturb- 
ance in the coal strata, the seams cropping out at a high angle of 30“ to 40°, and the 
coal much mixed with shale, so as to be of no value. The high angle of dip on both 
sides of the valley is, however, only local, and the shales and sandstones to the west 
indicate that the coal continues in that direction, with very little dip, as far as Biindamba 
Creek, while in a southerly direction an anticlinal axis of elevation brings the coal to 
the surface, with a dip to the north on one side and to the south on the other. 
* From the preceding paragraph it appears to be identical with the Goodna Seam. (B.L.J.)
