been used in furnace ; the conglomerates arc coarse, and pass into 
sandstone as on llie Hunter. 
Those are surmounted by beds of grit and sandstone and ferrii- 
gluous conglomerate, wliicli alternate together, the- whole presenting a 
scries of heds which, in colour, consistency, and all ])hysieal conditions 
of structure, arc in no degree dillercnt from beds of the same formation 
wliich I have e\'i)lored in various parts of tlie sea-board. Over the 
conglomerates of J-ieedy Creek, sandstones (piite undistingiiishable from 
those of the great sand.stoue territory of New fciouth Wales rise in 
succession, till the formation attains a height of from 1 ,d(H) to 1,S!()() 
feet above the sea, except where it caps the range opposite Jhngora, ' 
that point b(nng about 'ItM) feet higher. 
“ I do not doubt that coal in some abundance will be found in tlio 
range of those beds, the strike of whicli seems to be north-east, as on 
the coast.” 
Granite. 
The granite formation is of special interest, chiefly on account of its 
tin lodes, and from its having been the original source of the stream 
tin. 
There arc granites of at least two eruptions ; these may bo well 
distinguished at Captain Swiuton’s station, wlicre the following sketch 
plan is taken : —
