MINERAL EXHIBITS. 
That the collection made by this department is not lar^^er and 
more complete is due to the fact that, with the exception of the 
valuable collection of fossils, &c., &c., made by the Government 
Geologist, and the fossils and samples of Coal, &c., collected by 
the Examiner of Coal Fields, the whole of the specimens (embrac- 
ing samples of oi‘es, &c., from nearly every district in the Cctlony) 
have been collected since the commencement of the present year. 
The readiness with which owners and managers of mines have 
contributed samples, and the energy displayed by the oflieers of 
this de])artment in collecting and transmitting them, are deserving 
of the highest praise. 
It is the intention of the department to obtain from each 
district a complete collection of samples of every mineral possess- 
ing an economic value found therein, and to arrange the collecticui 
in such a manner as will enable the public to see at a glance the 
mineral pimducts of every district in the Colony. The making 
of such a collection will of course occupy some time, hut no 
efforts will be spared to make and arrange it as speedily as 
possible. 
The following are notes by C. S. Wilkinson, Esq., Government 
Geologist, on the Geological and Miueralogical CVdlection ex- 
hibited at the Metropolitan Intercolonial Exhibition, 1875 : — 
The geological collection which I have had the honor to arrange 
for the Department of Mines at the Intercolonial Exhibition 
comprises upwards of 1,000 specimens illustrative of the geology 
and mineral wealth of Xew South Wales. 
Owing to the short time at my disposal for this work, and to 
the recent establishment of the Geological Survey, this collection 
is not so complete as it might have been. ?7evertheless, with the 
assistance aftorded by the ATardens, Mining Eegistrars, and 
other officers of the Department of Alines, the Surveyor General 
and others hereafter mentioned, the fossils and minerals I have now 
arrmiged, fairly represent the principal geological formations with 
their mineral resources, and cannot fail to show their scientific 
and economic importance. 
Though an outline geological sketch is here necessary for 
reference, the present paper, I would premise, must be regarded 
rather as a general description of the collection exhibited than as 
a full exposition of the Geology of 'New South AV^ales. The latter 
will be found in the 3rd edition (published herewith), of ReinarJcs 
on the Sedimentary Formations of N'ew South fFales^ by the Eev. 
AV. B. Clarke, AI.A., F.G.S., whose extensive geological explora- 
tions in Australia command his authority on the subject.
