rough well-marked ridges, which follow the lines of strike of the 
hard rock. Where the hills are composed of dense and little- 
jointed intrusive rocks they usually take large rounded outlines, 
forming distinct and often somewhat prominent hills, but those 
formed of the more schistose and jointed rocks commonly show 
less relief and much less curved contours. The hills formed by 
granite are of very distinctive appearance, being usually bare, bald 
surfaces of hard rock, protruding from the surrounding plains. 
These liarc surfaces are commonly more or less pitted with shal- 
low small solution basins in which water collects during rains. 
The granite protuberances very often strongly remind one of rocks 
and islands standing up out of a sea, and along the south coast 
east of Albany, we may see exactly the same type of protruding 
granite rocks in the numerous islands which there are seen stand- 
ing quite similarly out of the actual sea. The similarity of 
scenic type is so exact as strongly to suggest identity of the 
sculpturing agencies. 
W'here the rising ground occupies a considerable area it 
frequently happens that smaller plains are found on the hills at 
various levels, so that an observer, in passing through a hilly 
region, frequently travels most of the way over very Hat surfaces, 
with little elevated country in sight, although on the whole the 
surface is a good tleal higher than the surrounding main plains, 
and from a <listance apjiears to form a distinct “range.” The 
“Black Rang-e" for example on being approached from the west 
side is seen for many mile.s away as a distinct high ridge, but plain 
after plain is crossed in getting to it without having almost any 
perceptible rising of the road, until one finds oneself travelling 
— still on fiats — over the top of the high country. This characteris- 
tic of the larger masses of high land is so usual as to be fairly 
rcgardable as normal. Another good exanqile is seen on the road 
from Meekalharra to Peak Hill. 'I'he Rolniison Range, on which 
Peak Hill stands, is seen from the ifiains to the south of it as a 
high bine range. l>nt one rises so gradually on to it, over plains 
wth very gentle slopes connecting them, that the top of the ridge 
is reached without having encountered any very ]ierceptible 
acclivity. And the top when reached is itself more or less a num- 
ber of small plains sei)arated by low-lying riclgcs of higher ground, 
and with IRxik Hill and another similar conical point of hard 
((iiartzitic rock standing u\) like i)_vramids from the plains. Peak 
Hill itself, it may be mentioned, is a very small affair, little more 
than a large natural cairn formed by the outcrop of a belt of hard 
(piarizite and the laliis therefrom. (A) the fiat at its foot, in the 
o])en cut workings of the l*eak Hill mine, the surface of the ground 
is seen to consist of a ferruginous conglomerate of stones and 
coarse gravel, many of the stones of which are well rounded, 
showing them to have been worn smooth l)y attrition in moving 
water. This is not at all a unique occurrence, for there is quite
