sir CHRISTOPHER WR'EN, int,

Thus, for Instance, a Bowling-green of near an Acre of Ground, may becovered with a Frame of long slender Pieces, without any other Prop than onthe Sides, for Vines , or other like Plants to run upon, so as to iliade thewhole.

Note here , That whereas the Ends of the several Pieces are to lie upon thosethat cross them, about the Middle thereof, it will be necessary at every Jointto abate both Pieces half-way, or near it j that one may be thus let into theother, and the whole reduced to a Flat. *But whether such Piece, so abated,doth end even with that on which it lies, > or doth lie over somewhat beyondit, is indifferent. And though that may seem more elegant, this, perhaps, maybe fitter for Use.

Each Piece, 1 fay, must be so abated half-way, or near it: For, whereasthose Beams, especially of a considerable Length, will, with the Weight, bowa little ; if this Abatement be somewhat less than half-way, (whereby withoutsuch bowing, the whole would somewhat rise in the Middle) it will by suchbowing be reduced to a Flat.

Note also , That a Frame thus contrived, needs neither Nail nor Pin ; theseveral Pieces fastening, as well as supporting one another. Yet, if it be tobear a great Weight more than its own, it will be convenient to fasten eachJoint with Pins ; and, if Need be, to strengthen it with Iron-plates, or line itwith other Pieces of Timber, to be fastened with Iron-bolts, to make amendsfor what is weakened by the Abatements at the Joints ; which will make thewhole Frame exceeding strong.
