3f Canoona, and those south-westerly from Maryborough, and to the strip 
f 3f country beween these two gold-fields we should look for the extension 
3f diggings. From the fact of these rocks being, as I believe. Upper 
I Silurian, gold-fields of the type of Caledonia and Anderson's Creek are to 
be expected rather than those of Sandhurst and Ballarat. Silurian rocks 
' igain make their appearance at Mount Caroline, the southernmost peak of 
. Perry's Eanges, Upper Burdekin. On the flanks of this hill their general 
iip is south-westerly. These rocks I should consider about the horizon of 
the auriferous series of Peak Downs, and that they represent the western 
portion of a great anticlinal axis, of which the Canoona and Maryborough 
beds represent the eastern. The dome of this axis has been denuded, and 
^one to form a portion of the material of that enormous carboniferous de- 
posit which, as Mr. Gregory informs me, extends from the junction of the 
Suttor with the Burdekin southward to Darling Downs. From Broad 
Sound northerly to Mount Elliot, the coast range is of granite and its 
rarieties, and in streams flowing exclusively through the granite, auriferous 
drift is found. 
Whether the extension of the Silurian system over this country has been 
entirely removed, and the granite represents only the base of this supposed 
anticlinal dome exposed by denudation (as the objectors to gold in granite 
would probably argue), is, of course, uncertain ; this much at least can be 
said, that the drift in which this gold is found is essentially granitic, and 
the resemblance to the granites of Omeo and Tambo Eiver, Gipps' Land, 
is remarkable. Basaltic lava flows, of greater or less extent, are met with 
in various parts of the colony, e.fj. between the Clarke river and Fletcher's 
Creek, the Valley of Lagoons, the Buckland table-land. Peak Downs, etc. 
Between the 19tli and 20th parallels of latitude the greater part of the 
country seems to be occupied by it. The tract of country included between 
the Clarke and Fletcher's Creek has received its Basaltic covering from 
local craters, which form conspicuous landmarks only from high ground ; 
they are too low to be seen in timbered country. The Basaltic areas are 
those best adapted for pastoral purposes in the tropics, their rich soils in- 
ducing the growth of the finer grasses with abundance of herbs, whilst 
their elevation above the sea renders the climate less enervating than that 
of the seaboard. From Mr. A. C. Gregory I learn that the representatives 
of our " older Basalts " of Philip Island, Cape Schank, etc., are found as 
dykes cutting through the Carboniferous series, and he draws the distinction 
(which holds in Victoria) between the Basaltic lavas of the plains and these, 
that the former were ejected from individual craters, the latter from fis- 
sures, forming dykes in rocks they traversed. 
The geology of Queensland, therefore, seems to differ little from that of 
Victoria, except in the relative areas occupied by each formation, the 
neighbourhood of Fitzroy Downs, from which the "VVollumbilla fossils have 
been received, affording the only prospect of novelty to the Victorian 
geologist.

Devonians in Noeth-East France. — It is well known that the De- 
vonian rocks of the Meuse extend towards the Boulonnais, and are con- 
nected with that enormous line of dislocation and upheaval which has 
brought up the coal-measures and subjacent rocks in a direction from
