14 Sir 'T. H. Pace’s Deferiptions of the 
courfe of bricks was carried up within the laft mentioned ribs 
or circles, upon a diameter of fix feet, whereby they became 
inclofed and joined with the firft mentioned brick-work, having 
the clay wall and wooden frame prefling behind them upon 
larger diameters. In finking lower, {mall curbs were at certain 
diftances (as will appear in the fection of the plan) placed to 
fupport the fteening, which confifted of two ftretching courfes 
of bricks, laid feparately, and keyed into the clay or back 
part of the brick-work by rough pieces of ftone, flint, &c. to 
prevent a flipping or lowering of the fteening by its own 
weight. The work was carried on from this period, without 
any material difficulty or difference in the clay (except the 
very extraordinary difcovery of a piece of a tree at the depth of 
300 feet from the top of the well, which is fhewn in the plan) 
until the appearance of water at 328 feet deep, by a {mall 
mixture of fand in the clay, with oozing of water from it; 
and at 330 feet deep, upon boring, the whole bottom of the 
well blew up, and it was with difficulty the workmen efcaped 
the torrents of water that followed them, which was mixed 
with a quick-fand that rofe forty feet in the bottom of the well, 
at which height it fill remains. The water rofe in fix hours 
189 feet, and in a few days within eight feet of the top of the 
well. It has fince been carefully analyzed by a chemift, and 
found perfe€tly good for every purpofe; and, it is prefumed, the 
quantity will be equal to every demand of public and private 
ufe at that place, as there has been, ever fince it was firft dif- 
covered, aconftant drawing of water, and it has hitherto been 
found impoflible to lower the well more than 200 feet, there 
has confequently always been a depth left in water of 130 feet. 
Tt is to be remarked, that the water is of a very foft quality, 
and, upon being drawn, has a degree of warmth unufual in 
common
