gritty conglomerates, studded with bould¬ 
ers transported by ice action, and de¬ 
posited in the mud of the ancient sea¬ 
floor. These basal beds are oil n regu¬ 
larly jointed, the joints being titled with 
ferruginous material. This is seen to the 
best advantage at the famous "tesselated 
pavement,” where the cross jointing is 
most regular. On these basal beds is 
resting a curious band of course grit 
stone, which in places appears up on the 
sides of the cliffs, and at others is faulted 
down to sea level, and finally disappears 
beneath the sea between I lie blowhole 
and the Arch. Numerous eaves and 
archways have been cut into the cliffs, 
:i"-' oil tiers are frequent. One magni¬ 
ficent, chimney rock, fully 160ft, in 
height, and balanced on a remarkably 
small base, is seen on the way to Water¬ 
fall Hay. The beds are filled with numer¬ 
ous fossils, the predominating types be¬ 
ing Spirifer convolnta, 8. dimvinii. Pro¬ 
duct ns brachythaeriis, Platysehisma 
ocnla, Sanguinolites elberidgei, and the 
various Slenopora and 1 Fenestella, with 
Proton tepoia ampin. On the north side 
of the bay the mudstones are conform¬ 
ably overlaid hy Mesozoic sandstones of 
the usual type. The surrounding hills 
are capped with later Mesozoic diabase 
of considerable thickness, jutting out in 
the south into a peak with steep 
columnar face. Other flows are notice¬ 
able to the south, ending in the Lantern 
h'oeks and the reefs of Fortescue Bay, 
and appearing far out to sea in the ill- 
famed Hippolyte Eocks. This diabase in¬ 
trusion is responsible for the cross-joint¬ 
ing of the basal beds mentioned before. 
The beds were heated excessively by the 
passage through therm of the immense 
masses of diabase now crowning tin hills, 
and on cooling joinls roughly rectangular 
in cross-section appeared, the shape ap¬ 
proximating to the. its mil jointing of the 
mudstones and the diabase, quite unlike 
tile hexagonal jointing of the basalts of 
the Giant’s Causeway. 
Sand dunes of rreent date fringe the 
shores of the bay, rising to a consider¬ 
able height on the Neck itself. Some ex¬ 
cellent aboriginal flint implements were 
found on the kitchen middens round the 
coast. The more recent geological pheno¬ 
mena are also represented by wide wave- 
cut terraces and raised beaches. 
ORNITHOLOGICAL NOTES 
By Clive E. Lord, Member Royal Australian Ornithologists’ Union 
The bird life observed during our few 
■days’ stay ul Eaglehawk Neck did not 
present anything of outstanding interest. 
There were sufficient birds in the bush 
near by I lie camp to add life and melody 
to the other charms of Nature by which 
we were surrounded. The sharp notes 
oi the green parrot (Platyeereits flaviveu- 
tris) in the gums, combined with the 
minor notes of the honryeaters in the 
scrub and heath, were continually ‘to be 
heard near the camp. Our Tasmanian 
nomenclature is rail) r behind the times 
in many places, owing to the changes 
wrought by time and man. Cbnsiquently, 
it was rather a surprise to some that one 
of the first birds noted was a wedge- 
tailed eagle (U. aurlax), which was glid¬ 
ing majestically over the slopes of Cash’s 
Lookout. It is a great pity that this 
splendid sped urn of bird life should lie 
commonly known ns eaglehawk. It is 
a true eagle in every respect, and a 
worthy rival of the famous golden eaglo 
of Europe. The Tasmanian form, in 
common with the majority of species, is 
even larger than the mainland one. Our 
other eagle, the wiliite-bellied sea eagle 
(II. leiii'-ogaster), was seen searching for 
food along the shores of Monge (or 
Pirates’) Bay. The only other Accipuri 
observed was the brown hawk (il. beri- 
gora). 
Only on • frogmonth, or morepork” (P. 
envieri), was seen. The spotted owl (N. 
maeulata) wus often observed near the 
camp during* the evening hours. It was 
also at night that the sharp "bark of 
the penguins could be heard, and these 
agile swimmers (E. minor) were often 
noted during the day. Out to sea could 
be discerned several albatrosses (Dio- 
ntedeidae), but at too great a distance 
for their exact species to tie ascertained. 
Several terns were seen, while the Pacific 
gull (G. paeifieus) and the silver gull (L. 
novae-lioILandiiae) were very common. The 
graceful form of tile heron (N. novae- 
hollandiae) was seen on the rocks, in 
sharp contrast, to 1 lie outline of the black 
(P. carbo) and the white-breasted cor¬ 
morant (P. gtraldi), that could be seen 
near by. The gannet (S. australis) was 
constantly proving his skill as a direr 
in the water near the camp. It is pro-
