the Office of Joifts, as *D, Fig. 2- after which, lay upon them
long Pieces of Ship-Plank, which joining two together, fliould
be as broad as the Wall, and nail or ipike them down to the
Joifts; and this is what we call the Platform or Floor E, Fig.
2. This Work being done, you let upon it the firft Courie of
the Inner-Wall B, which muft be railed as high as the other
and 1S Inches in Thicknefs at leaft j for in Balbns that are
pretty large and deep, where there is a great Weight of Wa-
ter, and the Sides of the Wall are long, you muft make the
Inner-Wall two Foot thick, as a means to prefervethe Balbn,
■ as well as •the Wall itfelf much longer.
You fhould not raife the Inner-Wall above half its Height
at firft, as fuppofe it ought to have fix Foot, you fliould raife
it but three Foot; becaufe it would be very difficult to throw
in and tread the Clay to the Bottom of the Bed, if the Wall
be railed its whole Height at once. The Space C, Fig. u
contained between the two Walls, called by the French, ie
Corroi, muft be filled with Clay to the Top of the Wall,
which fliould be built level with the other ; and the lame
Kneading and Treading muft be continued, till the Body of
Clay C be railed eaven with the Ground.
For working the Bottom F, Fig. 2. you are to fill the
whole Extent of the Work with Clay, to make a Bed of
18 Inches Thicknefs, beginning to knead it with that you
firft Ipread within rthe Inner-Wall and Joifts; and uniting
that and the Bottom together, which fliould be cover'd with
Gravel five or fix Inches deep, as you fee in Gy Fig. i>
which will preferve the Clay, and hinder the Fifli from dig-
ging. Inftead of graveling it, you may pave the Bottom;
but this is vaftly chargeable.
If the Bafon be in a Wood, or near any great Trees, *the
*Ground-Wall muft be built with Mortar made of Lime and
Sand, to flop the Roots of the Trees, which coveting the
Frelhnels of the Clay to nourifti them, and gathering more
<and more Strength, in the end overturn the Walls into Hie
Water. You muft likewife, for the Prefervation of your
^Balbns, every fix or feven Years, caufe Trenches to be made
.as deep as the Clay-Bottom, about the Walls, and in the
Middle of the Walks, not going too near the Balbn, or the
Hedges
