92 Report on the Coal said to have been found 
out, and the distance there would probably be about five 
miles. 
The intervening space is for the most part densely clothed 
with heavy timber trees and brushwood, consisting of Stringy- 
bark (Eucalyptus gigantica), White gums, Muskwood (Ew- 
rybia argophylla ), Wop-pole trees (Pomaderris elliptica), 
&e. &e. 
The fresh waters of the Mersey run for two miles, before 
they merge in those of the estuary, through an even and com- 
paratively level piece of alluvial land, admirably fitted for 
the plough, and yielding a rich natural pasturage, with no 
inconsiderable sprinkling of clover: this area narrows as it 
retires from the bay, until the hills on one or both sides shelve 
down abruptly to the very margin of the river. At different 
points on both sides of this flat may be traced a succession 
of terraces, each a few feet in elevation, indicating the recur- 
rence at intervals of an elevation of the surface, leading to 
increased depth of river channel and narrower volume of 
contents. Leaving the stream of the Mersey at its junction 
with the estuary on a south-west course, the grassy flat is 
soon found to be hemmed in by a highly-inclined bank of 
sand and pebbles, more or less rounded,—the detritus of a 
conglomerate formation, which is very prominently developed 
over the tract of country extending on the eastern side of that 
river in the direction of the ‘‘ Native Plains” and Deloraine. 
This highly-inclined bank, on the western side of the valley, 
corresponds to or is equivalent for ¢wo if not three terraces 
on the opposite side, and is crowned with a flat of some 
extent, which is thinly covered with grass upon a somewhat 
peaty and very moist soil: to this flat succeeds a series of 
rounded eminences, or, rather, ridges thrown out from an 
elevated tier of greenstone, stretching to the southward. 
These rises are at first gentle, with a soil of sandy loam and
