Chap. I. of Gardening. IOS*

After this fliort Advertifement, we may proceed to the
following Exercifes, which are fuppofed to be defigned up-
on Rolls of Paper, call'd Plans, and the Space upon the Side
is the Ground, upon which they are conceiv'd to be laid
down in a true and juft Proportion; that is to lay, convert-
ed from little to great. All thefe Exercifes are contain'd in
the four Plates at the End of this Chapter.

B y this Companion of the Paper with the Ground, you
will judge of the Relation they have one to another; and I
may truly affirm, that thefe Practices contain all that a Gar-
dener needs to know in Geometry, for enabling him to trace
out all Sorts of Figures upon the Ground, how difficult loever
they may be.

A Comparifon of the Taper with the Ground^ in what relates
to the Manner of Tracing, reduced to Twenty brattices.

THE FIRST PRACTICE.
To draw a. Right or fir ait Line upon theGromdyuith theCord.

Let the ftrait Line be ab, which is here fuppofed to be figure I.
twelve Fathom : meafure exactly this Length upon the PLATE t
Ground from A to B, and fix two Stakes there; then
ftraining the Cord from one to the other, mark the Line out
Upon the Ground with the Tracing-Staff, following the Cord,
fo as not to force it one way or other*

Observation.

This Practice is proper only for a Dlftance of about ii
or 15 Fathom, by reafbrt of the Difficulty you will have to
trace a longer Line, by the Side of the Cord, without making
it fwerve.

THE SECOND PRACTICE.
To draw a Right Line upon theGroundby the help of Stakesi

Suppose the Line to be drawn be found upon the Plan
to be a hundred Fathom long, as the Line c d, drive a Stake
