Directions in the foregoing Field or Meadow.

When you come into it, make for the North Side there-qf, (though any Side would answer the same End ;) then fix ona Place in the Hedge, suppose at A, and casting your Eye towardsthe opposite Side, fix on a Mark in the Hedge at B, to whichPlace chain, and as you advance take up the Left-hand or BrookOff-fet, as you were directed in the second Example; and atthe same Time take up the Right-hand Off-set; but when youhave measured 30 Chains on your base Line, your Staff will in-form you that a Perpendicular thereat doth arise into the subtend-ing Corner, upon which you’ll have a South Off-set; the firstPerpendicular thereto lies between the Staff and the Mark in theHedge at B ; {seethe \th or South Offset , Lest hand) then areyour Dimensions ended, which you may cast up in the Field, ifyou think proper: And if the Dimensions are to be planned,you’ll meet with Directions to effect the fame in Chapter theNinth.
