“ Thomas’s Mine . — At this point Thomas’s Mine hasheen opened on Portion 270, 
Parish of Goodna, the workings being on a dip of 15° to the south for one hundred and 
fifty yards. The thickness of the seam is about sis feet, of which four to five feet are 
available, as there are some bands of clay and shale, which vary considerably in 
thickness. The coal from this seam is hard and bright, and bears carriage better than 
the average of the district, while it is in good repute as a steam coal. The specific 
gravity is 1-44.

“ It makes a fair coke, but not equal to the coals further to the west, near 
Ipswich. About two hundred yards to the east of Thomas’s Mine the coal crops out in 
a gully. 
“ Coal Seain in Portion 252, Goodna. — To the south the seam dips for about a 
mile, and then rises again at an angle of 30°, the outcrop crossing the road on the 
north boundary of Portion 252 ; but a hundred yards further south it shows again in 
a horizontal position, with a thickness of six feet, the outcrop showing along the face of 
the hill for a quarter of a mile.* 
“ Thomas’s New Coal Mine. — To the south and west of this outcrop the lower beds 
of clays and shales are uncovered for a space of about a mile, when the coarse sand- 
stones again appear in horizontal beds, covering a fine seam of coal [the Aberdare], 
which crops out in Portion 270, parish of Bundamba [Goodna?], where it is worked by 
Mr. Thomas. The seam is eight to ten feet thick, but only four to five feet of workable 
coal. At the outcrop it dips 1° to the south, but rapidly increases, and at the back of 
the hill, two hundred yards south, the sandstones dip 10° ’to the south. The coal 
from this seam is not quite so hard as at Thomas’s Mine, Portion 270, Goodna, but 
seems to bo less mixed with inferior bands. The specific gravity is 1'40.

“ Thompson’ s New Coal Mine. — About half a mile to the northward of Thomas’s 
Mine, what appears to be the same seam is visible in a gully in the water reserve, and 
Et shaft has been sunk on the adjacent Portion Xo. 174, Bundamba [Goodna?] by J. M. 
Thompson, E.sq., and an excellent seam of coal cut at forty five feet, the dip being 17° 
to the west. The thickness is from six to ten feet, but there are some bands of shale 
and inferior coal which will probably reduce the workable portion to five feet. The coal 
is of a good, bright, reedy character, but rather tender and friable. It cokes very well. 
Specific gravity, 1‘38.

“ This small proportion of ash and large percentage of carbon places it at the 
liead of the Ipswich coals, both as a steam coal and for coke. 
This and the seam referred to in the preceding paragraph appear to be one and the same. [B.L.J,)
