i9"l PENDULUM OBSERVATIONS 339 
this object has been immensely helped by the telephone 
communication between the cavern, the transit instru- 
ment, and the interior of the hut. The timekeeper is 
perfectly placed. Wright tells me that his ice platform 
proves to be five times as solid as the fixed piece of masonry 
used at Potsdam. The only difficulty is the low tempera- 
ture, which freezes his breath on the glass window of 
the protecting dome. I feel sure these gravity results are 
going to be very good. 
The temperature has been hanging in the minus 
thirties all day with calm and clear sky, but this evening 
a wind has sprung up without rise of temperature. It is 
now - 32 0 , with a wind of 25 m.p.h.— a pretty stiff condition 
to face outside ! 
Sunday, July 2. — There was wind last night, but this 
morning found a settled calm again, with temperature as 
usual about -35 0 . The moon is rising again; it came 
over the shoulder of Erebus about 5 p.m., in second quarter. 
It will cross the meridian at night, worse luck, but such 
days as this will be pleasant even with a low moon ; one 
is very glad to think the Crozier Party are having such a 
peaceful time. 
Sunday routine and nothing much to record. 
Monday, July 3.— Another quiet day, the sky more 
suspicious in appearance. Thin stratus cloud forming 
and dissipating overhead, curling stratus clouds over 
Erebus. Wind at Cape Crozier seemed a possibility. 
Our people have been far out on the floe. It is cheer- 
ful to see the twinkling light of some worker at a water 
hole or hear the ring of distant voices or swish of ski.
