and, by analogy with the yellow lenticular patch of basalt-agglomerate (82) at Cape 
Wadworth, we may infer that the south end is also partly of the same rock. As the 
yellow patches lie almost horizontally it is highly probable that the island consists 
of alternating sheets of basalt and basalt-agglomerate (Fig. 3). 
In addition to bedding-planes visible near Cape Wadworth, there are dykes 
running vertically up the cliffs. Among the specimens collected by the ‘ Discovery ’ 
from this Cape, there are basalt-scoria (80), basalt-agglomerate (82), and a basalt (81) 
obtained from a dyke standing out on the cliff-face. Such dykes do not reach the 
top of the cliff but, after extending some way up a steep slope, end off at the base of 
the agglomerate. Only a quarter of an hour could be allowed on shore, but as the 
ship steamed into Lady Newnes Bay quite similar structure-lines were seen on the 
west side of the island and on the mainland (Cape Jones), areas which were possibly 
at one time continuous. The distribution of snow on the west side of the island points 
to gentle folding of the rocks about an east-and-west axis, but soundings of over 
150 fathoms in the channel show no continuation of this fold towards the west. 
Franklin Island. 
Franklin Ishmd is situated in latitude 76° 8' S. and longitude 168° 12' E., and 
until the ‘ Southern Cross ’ Expedition this was the most southerly land from which 
rock -specimens had been obtained. The island was discovered by Sir James Clarke 
Ross, who save its length as 12 miles and its breadth as G miles. He described its north 
side* as a line of dark precipitous cliffs between 500 and GOO feet high, exposing 
several longitudinal broad white bands and two or three bands of a red-ochre colour. 
The specimens he collected arc all basalts of one type,f while in the ‘ Southern Cross ’ 
collection there is a specimen of magma-basalt (limburgite) remarkable for the number 
and large size of the olivine-enstatite nodules. J 
From Mr. J. D. Morrison of the ‘ Morning ’ five specimens of similar magma- 
basalts with olivine-enstatite nodules were received ; with them was the following 
note : — “ Nos. 4 and 5 were taken from Franklin Island, from a belt of rock about 
30 feet thick running horizontally along one side about 300 feet above sea-level. 
Height of hill about 700 feet; very difficult to ascend, as the slope is composed of 
small stones lying at an angle of about 45°. Nos. 6 and 7 were broken from a large 
boulder lying at the foot of the hill. The beach is about half a mile broad and a 
mile long, almost flat and about 10 feet above sea-level. Large boulders and heaps of 
shingle are scattered over the beach, which is on the south-west corner of the 
island.”
