two extremities hanging lower than the middle part 
by many inches ; and confequently the foremoft 
part of the keel, indead of Aiding over the blocks, 
forced all the foremod ones away, for above 60 feet ; 
whereby that part of the keel reded on the bottom 
or floor of the dock, and the aftermod part reded 
on fuch of the blocks, as had efcaped the violence, 
which had difplaced the others. I11 this fituation the 
keel was very far from being drait ; and fo it was 
refolved to lift by main force the head of the diip, 
until the keel diould be drait ; and in that pofition 
to fupport it by the blocks, which had been forced 
away from their places. 
For this purpofe there were fet up, under the 
wales and other parts of the diip, to the length of 
near 80 feet of the dem, as many dioars, as were 
judged neceflary ; and alfo nine pair of bed-fcrews, 
three pair under each bow, and three pair under the 
knee of the head. At each flioar a workman was ap- 
pointed, to drive wedges between the heels of the 
dioars and the parts of the dock whereon they reded ; 
whereby the dioars were raifed end-wife, and con- 
fequently the body of the diip lifted at the fame time. 
While this was doing, the 18 fcrews were alfo at 
work : and between thefe efforts t the fore part of the 
diip was raifed upwards of 1 9 inches, fo much being 
neceflary to bring the fore part of the keel in a right 
line with the hinder part. 
In this fervice were employed about 270 men ; 
wdiereof about 144 worked at the fcrews, and the 
others worked at the flhoars with their mawls and 
wedges ; and the whole operation was performed in 
about feven hours.
