very like a guitar, and the name guitar 
plant is much more suitable. The flowers 
are in loose clusters, creamy white, anti 
in structure exactly like the flowers of 
waratah. The scientific name is Loma- 
tia, which is easy enough to be used as 
a popular name. Another member of 
the family on the lower slopes of Cash’s 
Lookout was Persoonia. The leaves were 
numerous, about half an inch long, lin¬ 
ear, and very sharp. The flowers were 
yellow, and single at the base of a few 
of the leaves- the fruit is a dirk berry. 
The only other member of the family 
observed was the common honeysuckle. 
This is an unsatisfactory name, for it 
is no relation to or at all like the honey¬ 
suckle of the Old Country. It is named 
Banksia, after Sir Joseph Banks, who 
well earned distinction as a botanist m 
the early days of Australian explora¬ 
tion. Banksia is easy and euphonious, 
and every effort should be made to 
encourage its use. The flowers in Bank¬ 
sia are clustered into dense oblong 
heads, but if a flower he dissected out 
it will be found to be built just as in 
waratah. A tree which we do not de¬ 
vote much attention to, simply because 
it is so common, is sheoak. Yet this is 
to the botanist perhaps the most in¬ 
teresting tree in Australia, or rather its 
family the Casuarfnas deserves this dis¬ 
tinction. It is a unique type of vegeta¬ 
tion, clearly of the flowering division 
known as dieotyls. it has the general 
appearance of a conifer. The water con¬ 
serving design of its anatomy reaches 
llie limit of effectiveness, and under 
what conditions it can have been evolved 
can only be conjectured to have been 
of persistent drought. 
GEOLOGICAL NOTES 
By W. H. Clemes, B.A., B.Sc. 
The geology of Eaglehawk Neck, 
though extremely simple, is neverthe¬ 
less very interesting. The main features 
of interest are the structures and fossils 
1.1 be found in the Permo-carbon- 
iferous mudstones, which are well-devel¬ 
oped along the coast. Tile cliffs have 
bold vertical faces, somewhat quaintly 
sculptured owing to the regular joint¬ 
ing, and reaching upwards in places to 
the height of fully 1,000 feet, lmt the 
bare rock is often beautified and screen¬ 
ed by the clinging vegetation, which finds 
a precarious foothold on the ledge- 
hollowed out by the moist sea winds. 
The horizontal bedding planes and ver¬ 
tical joints would lead one to imagine 
that the cliffs were the work of titanic 
builders, labouring to protect the land 
from the fierce assault of the waves, 
and building a wall that would reach 
even to the skies. The foundations 
must have been badly laid, as numerous 
faults arc visible, and the beds are 
sometimes slightly dipping to the south¬ 
east. The lower beds are gritty con¬ 
glomerates, whose studded surface hears 
eloquent testimony to the eokl of the 
early Peiimo-earbmiiferous age. The 
stones were transported there by the ice 
floes, which abounded in that great bay 
which includes most of what is now 
South-Eastern Tanmonia, and whose 
melting caused them to sink down to 
tho mud of that ancient sea-floor. 
Granite blocks are there, brought from 
the distant granite fringe fair out to 
sea, together with rocks from still older 
formations which have since disappear¬ 
ed. These basal beds have become 
curiously jointed, the joints being filled 
with ferruginous material. This is seen 
to the best advantage at the Tesselated 
Pavement, when' the cross-jointing is 
most regular. This is probably due to 
a mass of igneous material which was 
intruded into the rook immediately be¬ 
neath the portion now visible. The 
unrounding rock was raised to a high 
temperature, and, on cooling, took on 
the jointing of the intruded rock. 
The jointing along the lines of weak¬ 
ness has led to the formation of numer¬ 
ous eaves, arches, and chimney rocks. 
On the basal beds is resting a curious 
band of gritty sandstone, which appears 
faulted to different levels along the 
coast. Above this comes a zone filled 
with the remains of marine life, which 
again is succeeded by an almost barren 
zone. The chief fossils are Spiri f er 
convoluta. S. dairwinii, Productus 
braohythaerus, Platyscliisnin ocula, San 
gninolitps etheridgei, and the various 
Stenopoirie and Fenestell® together 
with Protoretepora ampla. 
The mudstones are succeeded by Jur¬ 
assic sandstones of the usual type. 
Cretaceous diabase has forced its way 
through the overlying strata, and is
