the head of ‘ Darkie’s Flat.’ These rocks, however, do not extend uninterruptedly 
from the range to both waters mentioned. To the north-west of Mount Gammie, sand- 
stones, conglomerates, and occasionally shales, belonging to the Ipswich Coal Measures, 
stretch from near the Miner’s Creek Bridge to within less than a mile of the old 
Talgai Township, and, continuing along the foot of the range, follow the south-west 
branch of Moeatta Creek to within a mile of the Condamine. On the south-east side 
of the range also, a patch of the same land of rock, but of small extent, occurs close 
to the west boundary of the towmship of Pratten.” 
The junction of the auriferous rocks wdth the [Ipswich] Coal Measures is spoken 
of by Aplin* as occurring “on the west side of the divide between Thane’s and Canal 
Creeks.” 
Report on the Auriferous Country of the Upper Condamine, ^'c . — In sinking a 
shaft about one mile from the old Talgai Township, a coal-seam was said to have been 
struck. “ On the authority of one of the men who were engaged in putting down the 
shaft, the thickness of the coal was from eight to ten feet. The reason assigned for 
there being no evidence of so thick a seam cut through and brought to the surface 
was that the coal was consumed by his party while sinking the remaining one 
hundred and fifty feet, the coal having been struck at seventy feet. Judging of 
its quality from the few fragments lying near the shaft, there would appear to have 
been a good deal of black shaly material associated with a clean, bright-looking coal.” 
In 1887 Mr. Hands described f as follows, the Ipswich Coal Measures of the 
neighbourhood of Beenleigh : — 
“The boundary of the Coal Measures runs in a south-south-east direction from 
Kingston Eailway Station, the beds extending away in a westerly direction towards 
Goodna and Ipswich. 
“ The measures consist of a series of sandstones, shales, clays, and seams of 
coal ; the beds are lying very flat and gently undulate, the direction of the dij) varying 
in different places. 
“ The following is a description of the places where the indications of coal were 
pointed out to me, starting from north of Beenleigh; — 
“ Shailer’s Selection (No. 2G1). — An outcrop of coal and black carbonaceous 
shale occurs in the bed of a gully running into Slack’s Creek. The section is partly 
hidden by water ; it is from twelve to thirteen feet thick, and consists of alternate 
layers of coal and a very carbonaceous shale, with one small band of sandstone about 
four inches thick. 
“ The bottom portion is said to contain the best coal. From this part I broke off a 
few large lumps of hard bright coal. The thickest coal without bands of shale is from 
fifteen to eighteen inches thick. The bed is dipjn'ng about 6° to N. 35° E. in the 
direction of the top of the ridge, where the boundaiy line of the schists occurs, about 
half-a-mile distant. ... I brought away a piece of this coal for analysis. It gave — •

The coke was brittle and compact, the ash light-grey in colour. The ash is naturally 
very high in a sample of coal taken from the outcrop of a seam.
