ay--temp. -12 deg.,
clear sky. Went to ice caves on glacier S. of Cape; these are really
very wonderful. Ponting took some photographs with long exposure
and Wright got some very fine ice crystals. The Glacier Tongue comes
close around a high bluff headland of kenyte; it is much cracked and
curiously composed of a broad wedge of white neve over blue ice. The
faults in the dust strata in these surfaces are very mysterious and
should be instructive in the explanation of certain ice problems.

It looks as though the sea had frozen over for good. If no further
blizzard clears the Strait it can be said for this season that:

The Bays froze over on March 25.
The Strait ,, ,, ,, April 22.
,, ,, dissipated April 29.
,, ,, froze over on April 30.

Later. The Hut Point record of freezing is:

Night 24th-25th. Ice forming mid-day 25th, opened
with leads.
26th. Ice all out, sound apparently open.
27th. Strait apparently freezing.
Early 28th. Ice over whole Strait.
29th. All ice gone.
30th. Freezing over.
May 4th. Broad lead opened along land to Castle
Rock, 300 to 400 yds. wide.

Party intended to start on 11th, if weather fine.

Very fine display of aurora to-night, one of the brightest I have ever
seen--over Erebus; it is conceded that a red tinge is seen after the
movement of light.

_Saturday, April_ 29.--Went to Inaccessible Island with Wilson. The
agglomerates, kenytes, and lavas are much the same as those at Cape
Evans. The Island is 540 ft. high, and it is a steep climb to reach
the summit over very loose sand and boulders. From the summit one
has an excellent view of our surroundings and the ice in the Strait,
which seemed to extend far beyond Cape Royds, but had some ominous
cracks beyond the Island.

We climbed round the ice foot after descending the hill and found
it much broken up on the south side; the sea spray had washed far up
on it.

It is curious to find that all the heavy seas come from the south
and that it is from this direction that protection is most needed.

There is some curious weathering on the ice blocks on the N. side;
also the snow drifts show interesting dirt bands. The island had a good
sprinkling of snow, which will all be gone, I expect, to-
