perpendicular to your Breast, that shall represent the first Main-line in the Fields

*. Fix upon a Point therein as at A, and from your Scale take30 Chains, 4 Links (though the 4 Links cannot be adjudged aton this Scale,) and lay it from A to B, which Points limit theMain-line ; upon the Left-hand Side thereof lay down those Di-mensions that were taken up on that Side in the Fields; the Right-hand Side is appropriated to all those Dimensions entered in sheRight-hand Column of the Field-Book, which being placed be-fore you, proceed thus:

3. At the Beginning at A, it is no Perpendicular, neither inthe Right or Left hand Columns; but at the End of 44 Links,it is 1 Chain, 71 Links of a Perpendicular to the Right-hand,therefore take 44 Links from your Scale, and lay it on the Main-line from A towards B, at which Point erect a Perpendicular tothe Right-hand, by Prob. 3. Chap. 2; otherwise apply the Endof the Scale upon, and parallel to the Main-line, letting or fix-ing one Corner of the Scale to the Point made with your Di-viders in the Main-line, 44 Links from A, the Beginning,and from thence draw a Perpendicular or obfeute Line, whereonlay down I Chain, 71 Links, the first Perpendicular; thenfrom A to this Point, draw a penciled Line. Aho lay down oneChain from A in like Manner, at which Point erect another Per-pendicular as you did the former, upon which lay off your secondPerpendicular = 3.52, to b, and with your Pencil join this tothe End of the last Perpendicular; then take in your Dividers3 Chains, 70 Links, and lay it on the Main-line, as before, atwhich Point draw an obscure perpendicular Line on the Left-handSide; upon which lay down 4 Chains, 40 Links to t; withScale and Dividers draw a Line between t and A, and lay downthereon the N. E. Off-set, beginning at A; this being done,take from the Scale 5 Chains, 72 Links, lay it down as beforefrom A towards B, to which Place draw a Line with the Pencilfrom t, which will represent Part of the Hedge between thisField and Damsels; and as the fame Hedge on the Right-hand isat Right-angles to the Main-line, raise a Perpendicular thereat,upon which lay down 2 Chains, 2 Links to e, and then, with aPencil, draw a right Line between d and e, and also one betweene and b, the former will represent the Remainder of the Hedge
