56 Personal Observations in the 
corded amongst those geological wonders which in different 
* countries have so frequently exeited the curiosity of even the 
most thoughtless of mankind. There is also a very interesting 
' group of boulders on Dr. Baynton’s run. 
The second species of granite on the dividing ranges, con- 
sists of fine crystallized felspar, with a small admixture of 
mica and quartz, the latter in minute particles. This granite 
constitutes the higher ranges on Mollison’s run, and appears 
similar to that at Mount Macedon; it exhibits a strong ten- 
dency to split perpendicularly. ; 
. The ceinted spot which supplies the natives with stone 
(phonolite) for their tomahawks, and of which I had been 
informed by the tribes 400 miles distant, I was unable, at 
this period of my journey to trace out ; but subsequently 
was fortunate enough to hit upon it accidentally while in 
sie of other objects, with the assistance of F. Mackenzie, 
sq. , 
Three miles east of Lancefield is a lofty chain of hills, - 
running nearly north and south; the highest summit of which 
is called Mount William. These ranges are intersected by the 
road leading from Lancefield to Kilmore, and which divides the 
basaltic strata, on the north from the clay slate rocks and slate 
of the southern portion of the range. The basalt gradually 
changes its specific character, northward, till at Mount Wil- 
liam it becomes distinct phonolite, of a hard and glassy tex- 
ture. A most excellent stone for macadamizing roads occurs 
in this locality, and will be a treasure to the neighbouring 
‘district, when the progress of the country shall demand its 
application. Good brown iron ore also occasionally occurs, 
though not in great quantities. 
Having observed on the tops of these hills a multitude of 
fragments of stones which appeared to have been broken 
artificially, and which I recognised as phonolite or clink- 
stone, I was led to trace them to the source from which 
they appeared to have proceeded, a spot three-quarters of a 
mile eastward, on somewhat lower ranges. Here I unex- 
pectedly found the deserted quarries (kinohahm) of the 
aboriginals, which I had previously been unable to discover. 
= The phonolite (tadijem), as before mentioned, is that of 
which their tomahawks are formed. The quarries which extend 
over an area of upwards of 100 acres, present an appearance 
somewhat similar to that of a deserted gold field, and convey 
a faithful idea of the great determination displayed by the 
ab originals, prior to the intrusion of the white races. They
