IRON. 
Evert exertion has been made to obtain a complete and 
reliable statement of the quantity and value of the iron ore 
raised, and of the iron smelted, but the attempt has not been 
successful. ISo far as can be ascertained, some 3,000 tons of cal- 
cined ore from the Eitzroy Mine gave 2,394 tons of ]3ig iron, 
which sold on an average for £6 ])er ton. The iron ore is said to 
be a very line quality, but somewhat dilUcult to smelt ; it yields 
after calcining about 60 per cent, of iron. The Lilhgow Yalley 
Iron 'Works are progressing very satisfactorily, and will probably 
bo complete in the course of a few months. At Brereton’s Mine, 
Berrima, some 1,000 tons of ore were raised during the year 1874. 
The following paper on tlie Iron Ore and Coal Deposits 
at AVallerawang, Ncav 8outh Wales, by Professor Liversidge, 
University of Sydney, Avas read before the Eoyal Society, 9th 
December, 1874 : — 
Many are probably well aware that there are large deposits of iron 
ores and extensive hods of ccfal in the ncighboiirliood of WalleraA^'ang ; 
but comparatively few, perhaps, are in possession of any very definite 
information concerning tliem. I therefore beg to lay before you the 
substance of some uotes, taken during a brief visit which I made in 
tlie early part of August last, and the results of my subsequent examina- 
tion of tlie samples of tlic ores and coals Avliich 1 then collected. 
I much regret that I cannot afford any general and comprehensive 
account of the geology of the district; and that it is ordy in my 
power to speak definitely upon the actual deposits of iron ore, coal, 
and the closely associated limestone, Eor, owing to an unfortunate 
accident Avhich I met with to my foot, within a few days after my 
arrival at Wallerawang, 1 was entirely pi'cvented from making any 
detailed investigation of the various strata and dcix>sits other than of 
those wliich folloAV. 
I very much regret too that I had to relinquish the idea of working 
out the geological section of the district ; but as Mr. Clias. Wilkinson, 
the Geological Surveyor, recently appointed by the Government, is 
noAV engaged making a stirA'ey of the district, we shall 2>rohably soon 
he in possession of a complete report upon the whole of the coal 
measures and iron deposits of this area, and in a much fuller and more
