The similarity between them all and those flanking the ranges is so great 
that I am inclined to regard them as belonging to the same Cainozoic division, 
and to attribute the difference in altitude to faulting. As shown by Mr. 
Jas. H. Wright, in his valuable paper * on an area in the Morwell Valley, 
faulting on a large scale has taken place during Cainozoic times, and though 
as yet there seems to be no distinct evidence of great faulting in the Agnes 
River district, later observations may prove such to be the case. For the 
present the flanking deposits are provisionally referred to as Miocene. 
The occurrence of the white “ pug ” beneath the basalt on Pinkerton's 
allotment, and the similarity of it to the white clays found in the stanniferous 
and lignitiferous series, tends to prove that the basalt is of later age 
than the sediments, thus placing it apparently with the basalts described f 
by J\fr. Murray, and synchronizing the sediments with the lignite-bearing 
beds to which he refers. 
Jurassic, t 
The Mesozoic rocks constituting the foundation of the ranges belong to the 
coal series of Jurassic age, as shown by the fern fossils obtained, the general 
lithological characters of the rocks, and the structure of the rock masses. 
They extend for many miles in an easterly and westerly direction, and, in 
fact, stretch in an almost unbroken mass from near Lang Lang on the west to 
the sources of Merriman’s and Bruthen Creeks on the east. The only breaks 
along the line of the Great Southern railway may be seen across the valley 
of the Tar win River in the Leongatha district, where volcanic and sedi¬ 
mentary deposits of Cainozoic. and Recent age respectively occur ; and at 
Foster, where a tongue of the Silurian of Cape Liptrap is found. In the 
former locality, moreover, the Jurassic beds in all probability underlie the 
Cainozoic and Recent beds at no great depth, and near Foster the Jurassics 
overlie the Silurians a short distance back from the foot of the ranges. 
In the neighbourhood of Welshpool, on the northern side of the railway 
line, and in Lamont’s and Shady Creeks, the rocks consist of grey, brown and 
yellow, massive, fine felspatliic, argillaceous and micaceous sandstones and 
flagstones, and greyish-yellow mudstdnes. Many of them are greatly 
jointed, and contain fragments of black coal and plant fossils in places. 
They dip generally from IV to V. 20° E., at angles varying from 1° to 23°. 
Fragments of rocks showing Angiopteridium spatkulatum , McClelland, 
and Alethopteris australis , McCoy, in great profusion may be found in a 
small gully in allotment 67, parish of Welshpool. Here, also, several 
specimens of coniferous plants resembling Araucarites , as regarded by Mr. 
Robt. Etheridge, Jun,, were found by Mr. George Christensen, wdio accom¬ 
panied me over portion of the locality. 
The spurs in this southern termination of the ranges have altitudes of 
between 400 and 500 feet above sea-level. 
Further north, towards the source of Nine Mile Creek, the rocks are 
bluish-grey and yellow mndstones and clays tones, containing small patches 
of black coal and impure clayey coal. These rocks disintegrate into a 
whitish soil with the black coal showing distinctly in the bedding places. 
They dip generally S. at from 15° to 26°, and in places have fragments of 
Angiopteridium spatkulatum.
