“According to this return, therefore, there were four seams of coal of sufficient 
thickness to pay to work passed through in the boring-viz., a four feet seam at one 
hundred and sixty feet in depth, a four feet one inch seam at one hundred aiid ninety 
one feet, a five feet three inch seam at two hundred and sixty nine feet, and a seven 
feet eleven inch seam (including eight inches of band) at two hundred and seventy eight 
feet in depth. Unfortunately none of the cores of coal wore kept, so that 1 was unable 
to see the quality of the coal. 
“ A sample of the bottom seam (the seven feet eleven inch seam) was sent to 
Mr. A. C. Gregory, who reports as follows: Percent

A fair coal for steam purposes and household use, also for smith s wor i. 
percentage of ash is probably due to ddhris from the boring being mixed with 
coal would answer admirably where an avoidance of smoke was an ob3ect, as the 
percentage of the volatile hydrocarbons is small. The site of the borehole is only 
about ten or fifteen chains from the Logan Eiver. Mr: Downman tells me that 
steamers of two hundred tons burden have come up the river to this point tor the 
purpose of carrying away timber, so that there would be no difficulty in the way ot the 
conveyance of the coal to the Brisbane market. 
“ At present the nearest available Railway Station is Kingston, about seven miles 
distant. The Logan Village line passes about half-a-mile from the spot, but it is on the 
opposite side of the Logan River. ^ , , j. 
“I was informed by Mr. Downman that coal can be seen outcropping 
Chambers Creek, in the same Selection, when the water is low. 
“Mr. Watt accompanied me to his Selection (No. 11), three miles south-east ot 
the Loo'au Village, where the following section of rocks is exposed in a gully:—

Black and brown shales, with coaZ and thin bands of sandstone ... K 0 
The dip is 8° W.S.W. A shaft forty seven feet in depth has been sunk in the 
gully close to the base of the black and brown shales. A seam of cannel coal, about a 
foot thick, was cut near the top of the shaft, and, lower down, a seam of coal about 
fifteen inches in thickness. A proximate analysis of a piece of this coal is appended :

The coke was hard and somewhat compact ; the ash was of a slightly rcddish-grey 
colour. The coal was hard and bright, with thin scales of silica on its faces, t i 
would account for the high percentage of ash. These scales of silica would proba y 
not occur at any depth from the surface. In testing this ground foi- coal, it would 
better to sink or bore lower down the gully, on the flat to the dip of t e e s. 
“ On the top of the ridge at the head of this gully there is a bed of freesto 
least one hundred and three feet thick. Mr. Watt has had some ^P^imens of this 
stone faced ; it would make an excellent building stone, being hard and durable, 
ridge extends right across the Albert Eiver.
