“ The dip of the seam being to the north-west, it passes under Bundamba Creelr, at 
a distance of four hundred yards, and the opposite bank rises into an undulating tract 
of basalt, having a length of four miles from the Bremer Eiver south-westerly, and a 
breadth of two miles from Bundamba Creek to the boundary of the Town of Ipswich ; 
and as the Carboniferous strata are found to dip and pass under the basalt along the 
whole of the margin of the igneous rock, it may be inferred that the coal beds arc 
only interrupted by the Assures through which the basalt has been erupted. 
‘‘‘Goal at 3Iihi Greek . — Crossing to the north-west of the igneous tract, the 
Carboniferous rocks aro found rising to the surface in the Town of Ipswich, and several 
small seams of inferior coal aro exposed in the cuttings for railway and roads ; and at 
the junction of Mihi Creek with the Bremer River, two large seams of coal crop out, the 
upper being exposed in the bed of the river, the adjacent Eailway Ctitting, and at the top 
of thehill on the Bine Mountain lload,the outcrop trendingnorth-east towards the Tivoli 
Mine. In the Eailway cutting the dip is 14°to the S.S.B. The quality of this coal is 
inferior, <and evidently much disturbed at the outcrop, and the beds of sandstone and 
shale vary considerably in thickness in the space of a few yards. 
“ Eastwood nine . — The second seam is about a hundred feel below that exposed in 
the Eailway cutting, the outcrop showing in the gully under the Eailway Bridge. It has 
a thickness of seven feet, but there are several thin bands of shale. This seam is worked 
at a point about three hundred yards to the N.N.E. by Messrs. Archibald, as the East- 
wood Mine, where the dip is 7° to the S.E. The coal is bright and bituminous, but very 
soft, and breaks small in carriage. It cokes well. iSpeciAe gravity, 1'4.

“ Tivoli nine . — -On the line of outcrop of the upper seam, at the distance of one 
and a-half miles, is the Tivoli Mine, which is worked by a drive of six hundred yards 
on a dip of 14° to the S.S.E., the thickness of the seam being Ave to six feet. The coal is 
bright and bituminous, very tender, breaking into small cubical pieces so easily as to 
scarcely bear carriage. It, however, makes excellent coke. SpeeiAc gravity, 1-33.

“ Blond and Wrifjli fs Seam . — The outcrop of a thin bod of sandstone, which covers 
the Tivoli seam, leads about a quarter of a mile cast to Blond and Wright’s Mine, w'hich 
is wmrked on the same seam, on a dip of 15° to tho S.S.E. The coal is a little 
harder than at tho Tivoli Mine, but in other respects not of equal value. SpeeiAc

“ On the north-east side of these workings a fault occurs, and the seam is thrown 
downwards, and worked at a lower level on both sides of the road, on the descent to 
Sandy Creek. The qu.ality of the coal does not improve in thi.s direction. 
“ new nine. — About a quarter of a mile to the north of the Tivoli Mine, a seam 
of coal has recently been opened, showing a thickness of eight feet, but some bands of
