this point her forward bridge fouled with the
bottom, and operations came to a standstill
while the obstruction was being removed with
the aid of pneumatic tools. A second spell
of hauling brought her 10 yards nearer shore,

When all was ready the pumps began to
draw water in cataracts from the interior of
the vessel, while air-compressors forced the
water out of the camels. Sim-
ultaneously the capstans got
to work, and sundry tugs lent
their assistance. The com-
bined effects of increased buoy-
ancy and haulage were soon felt, and the

she was allowed to remain in this position
while preparations were made for the more
difficult process of bringing her on to an
even keel. For this task the shore capstans
were of no use, as the masts, which would
give the necessary leverage, pointed land-
wards. The Ranger and Enterprise were ac-
cordingly brought up and moored by 7-ton
anchors, in line with the two masts, and at
