SOUTH 
position was lat. 69° 11' S., long. 61° 5' W. We had now 
twenty-two and a half hours of daylight, and throughout the day 
we watched the threatening advance of the floes. At 6.45 p.m. 
the ship sustained heavy pressure in a dangerous position. 
The attack of the ice is illustrated roughly in the appended 
diagram. The shaded portions represent the pool, covered 
with new ice that afforded no support to the ship, and the 
arrows indicate the direction of the pressure exercised by the 
thick floes and pressure-ridges. The onslaught was all but 
irresistible. The Endurance groaned and quivered as her star- 
board quarter was forced against the floe, twisting the stern- 
post and starting the heads and ends of planking. The ice 
had lateral as well as forward movement, and the ship was 
twisted and actually bent by the stresses. She began to leak 
dangerously at once. 
I had the pumps rigged, got up steam, and started the 
bilge-pumps at 8 p.m. The pressure by that time had relaxed. 
The ship was making water rapidly aft, and the carpenter set 
to work to make a coffer-dam astern of the engines. AU hands 
worked, watch and watch, throughout the night, pumping ship 
and helping the carpenter. By morning the leak was being 
kept in check. The carpenter and his assistants caulked the 
coffer-dam with strips of blankets and nailed strips over the 
seams wherever possible. The main or hand pump was frozen 
up and could not be used at once. After it had been knocked 
out Worsley, Greenstreet, and Hudson went down in the 
bunkers and cleared th6 ice from the bflges. " This is not a 
pleasant job," wrote Worsley. " We have to dig a hole down 
through the coal while the beams and timbers groan and crack
