To make these Floorings, the Boards must be nailed at each end upon
every Joist, to the end they may not warp; these Boards or Planks being
cover'd with Straw, to hinder the Lime from wasting the Timber, the
first Bed must be laid, made of a mixture of Mortar and little Stones a
hand breadth, which must be beaten a long time with Iron-Levers, and so
it must make a solid Crust which must be nine Inches thick; upon it
shall be laid the _Noyau_ or _Ame_, which must be at least six inches
thick: It must be made of Cement, with which must be mix'd one part Lime
for two parts of Cement. Upon the _Ame_ or _Noyau_ is placed the
_Parement_ made with the Rule, afterwards it must be scrap'd and all the
Eminences and Inequality taken away: After that must be laid a
Composition of Lime, Sand and beaten Marble, to fill equally all the
Seams or Joints.

If a Flooring be to be made in the open Air, as upon _Terrasses_, that
may endure Rain or Frost without any Damage; you must nail upon the
Joists two Ranks of Boards across, one above the other; and having laid
the first Bed, as is said before, it must be Paved with great Square
Bricks two Foot Square, which must be hollow'd in the Ends in the Form
of a half-Channel, the breadth of an Inch, which must be fill'd with
Lime mixed with Oil. These Square Bricks must be higher in the middle,
sloping two Inches for every six Foot; that is to say, a Forty-eighth
Part. Upon these Square Bricks must be laid the _Ame_; upon which, after
it has been well beaten, as well as the rest, must be put great Square
Stones; and to hinder the Moisture from hurting the Boards, it is good
to pour as much of the Lees of Oil as they will soak up.

The under part of the Flooring, and the _Plat-Fonds_, must be made also
with great Care. To make the _Plat-Fonds_ or _Flat-roofs_, in the Form
of a Vault, you must nail to the Joists of the Boards, or to the Rafters
of the Roof, from two Foot to two Foot pieces of crooked Timber, and
Choice must be made of Timber that is not apt to rot; such as, _viz._
_Cypress_, _Box_, _Juniper_, and _Olive_; no _Oke_ must be made use of,
because it will warp and crack the Work. The Joists being fastened to
the _Summers_, you must fix to them _Spanish-Broom_ with _Greek-Reeds_
well beaten. These Reeds are in stead of Laths, which at pres
