102 Mr. Barnard’s Method of removing Ships 
which filled her for four days equal to the flow of the 
tide. Having fully informed myfelf of her fitua- 
tion and the flow of fpring tides, and being clearly of 
opinion fhe might be again got off, I recommended, as the 
firfl neceflary ftep, the immediate difcharge of the cargo ; 
and, in the progrefs of that bufinefs, I found the tide al- 
ways flowed to the fame height on the Hup ; and when 
the cargo was half difcharged, and I knew the remaining 
part fhould not make her draw more than eighteen feet 
water, and while I was obferving the water at twenty-two 
feet fix inches by the fhip’s marks, lire inftantly lifted to 
feventeen feet eight inches, the water and air being be- 
fore excluded by her preflure on the clay, and the atmo- 
fphere adding upon her upper part equal to fix hundred 
tons, which is the weight of water difplaced at the dif- 
ference of thofe two draughts of water. 
The moment the fliip lifted, I difcovered fhe had re- 
ceived more damage than was at firfl: apprehended, her 
leaks being fuch as filled her from four to eighteen feet 
water in one hour and a half. As nothing effectual was 
to be expected from pumping, feveral fcuttles or holes in 
the fhip’s fide were made, and valves fixed thereto, to draw 
off the water to the loweft ebb of the tide, to facilitate 
the difcharge of the remaining part of the cargo; and, 
after many attempts, I fucceeded in an external applica- 
tion
