Silky Shale (Silurian); 9, very Micaceous
Schist (Silurian).

Latitude 25 degrees 40 minutes South, Longitude 120 degrees 35 minutes
East : Found in the Frere Ranges. : 10, Ferruginous rock (Tertiary); 11,
portion of a seam or joint of a rock; 12, very fine soft purple slightly
micaceous rock (Silurian); 13, white micaceous slaty sandstone
(Silurian).

Latitude 25 degrees 39 minutes South, Longitude 120 degrees 40 minutes
East : This rock was broken off the face of the side of a bank of brook.
It is rather soft, and would split; it is all in layers. I cut my
initials in it with a chisel. : Purple brown slate (Silurian).

Latitude 25 degrees 40 minutes South, Longitude 122 degrees 20 minutes
East, Mount Moore : Many ranges and some grassy country running from
longitude 122 to longitude 124 degrees, generally composed of this
description of rock. : 15, Rough quartzite (conglomeritic) Tertiary; 16,
rough quartzite with white band, brown and purple (Tertiary).

Latitude 25 degrees 32 minutes South, Longitude 124 degrees 17 minutes
East : Taken from rough range rising out of gently undulating desert.
(July 5th.) : White flinty rock; consists in the main of Silica, with
Magnesia and Alumina; it also contains water and traces of the Alkalies.
It is probably derived from the decomposition of granite. The "rough
ranges" are perhaps granitic.

Latitude 26 degrees 6 minutes South, Longitude 124 degrees 46 minutes
East : From a low table hill (Alexander Spring). : Translucent greenish
quartz. Impossible to state the probable age.

Latitude 26 degrees 2 minutes South, Longitude 125 degrees 27 minutes
East : This sandstone is the usual rock found in all the country from
longitude 122 degrees to 126 degrees 30 minutes. In it are receptacles
for water, and all the rising ground is composed of it. Very often one
side of the rise forms a cliff. Where this is taken from there is a long
line of cliffs with many creeks running from them, and low cliff-hills
all about. : Light red sandstone (desert sandstone, Tertiary).

Latitude 26 degrees South, Longitude 126 degrees 30 minutes East : From
the farthest ranges westward from telegraph line; good grassy country in
flats. The dark piece from a salt gully. (August 8th.) : 20, Silico
felspathic rock impregnated with Micaceous iron (probably from a dyke);
21, 22, green schist (Silurian).

Latitude 26 degrees 12 minutes South, Longitude 128 degrees East : In the
Cavanagh Ranges. Many ran
