of Pelican Creek to the Bowen River, near Exmoor. Erom Exmoor south-eastward to 
point between Mount lllaloiig and Buugella Station, the fault divides the Middle 
Pormatioii from the metamorphie rocks. Thence south-eastward to the granite range of 
Mount Dalrymple the Lower Formation comes in immediate contact with the meta- 
laorphic rocks, sweeps round the granite range, on the coastward side, by Mackay and 
Bloomsbury Station, and, on the south, surrounds the granite mass of Mount Bridgman 
'wid Mount Spencer, reaching the sea near Cape Palmerston. 
Beneath the Desert Sandstone of the Carborough Range the Upper Formation 
of the Bowen River Coal Field is seen. Plant-remains, including Glossopteris and 
V- ) Splienopieris, were observed by Mr. Maitland in some sandy micaceous shales at a 
^atorfall in Bee Creek. A few yards up the creek a seam of impure coal, one foot in 
iickness, dips to N. at 10°. A tributary of the same creek exposes a seam of coal 
least six feet in thickness, but interrupted by bands of carbonaceous shale. 
About three miles west of Lenten Downs Station a bed of coal, two feet in 
oicknesg and of fair quality, was met with in a well at a depth of about fifty feet. A 
Similar seam was met with in a well between Lenten Downs and Greendale.* * 
From the heads of the Isaacs to the heads of the Dawson the whole country 
^Ppoars to bo made up of strata belonging to the Bowen River Formation, but our 
Dowledge of this district is very limited. Mr. Daintree, in 1872, f besides the Bowen 
iver, mentioned the occurrence of Palaeozoic Coal-Measures on the Dawson, Comet, 
■'-^ekenzie, and Isaacs, remarking that “ numerous outcrops of coal have been observed 
these streams. No comm(;rcial use, however, has yet been made of any of them, as 
® measures generally are too far inland to be made available until the railway system 
of the 
country is extended in that direction.” From considerations already given I have 
1 • . 
'^med this area between the Middle and Upper Formations of the Bowen Coal Field. 
Mr. Daintree described, in 1870, J certain auriferous drifts at Cement Hill, about 
Sixteen miles from Clermont. Mr. Rands gave a fuller account of the same deposit in 
Report on the Clermont District.” § The hill consists of (1st) fifteen to thirty feet of 
tj^^S^omerate, composed of boulders and pebbles of schist and also small quartz pebbles, 
6 whole cemented together by clayey cement formed from the degradation of the 
is, lower four or five feet of the conglomerate form the washdirt in which the gold 
(2nd) Beneath the conglomerate is a fine-grained silt or shale, from one to four 
is 
in thickness, dipping W.S.AV. at from 5 to 25°. Numerous well-preserved im- 
feot 
of Olpssopferis occur in this silt. (3rd) Beneath the silt or shale is another 
. > much finer than the upper one, consisting of small schistose pebbles, but contain- 
lo° more quartz, the quartz pebbles often predominating. This drift, which is 
fke n “tish,” is in places forty feet in thickness. In some parts of the hill 
lossopferis shale rests immediately on the schists, but oftener on the “tish.” It is 
®ome places over forty feet in thickness. No gold has been found in the lower drift, 
ehn Hurley’s, and at the Four-mile near Clermont, the drift is of the same 
liter as that at Cement Hill, and Glossopterin is also found at Hurley’s,
