Next after you have thus done, and are come to the Furlong where you began, express in your Book the Name of your Field, and the Furlong; then in the middlemoft, or greater Column, note down the Name of the Free holder that first begins it, with the number of his Lands; against which in the two firit Columns towards the Left-hand, write the Breadth of the Lands at each end and in the three last put the reduced Breadth, Length and Quantity; which done, fet down the Nine of the Free-holder that lies next, and the number of his Lands, fogether with the Length, Breadth and quan-tity, as before, and so proceed in order till you have finished the Furlong.
And so on from one Furlong to ano; ther, till
have finished the whole Field.
But that you may the more fully under. stand the Form thereof : I shall fhew you in the following Example an absoJure Method , how you may effect the fame,

After this manner you are to proceed from one Furlong to another, until you have finished your Field-Book ; which be. ing done, you are next to make a particu. lar of every Maris Arrable, Leys and Meadows severally, to which purpose, upon a fạir sheet of Paper, you are to make so many Columns
are Free... holders, every
whereof is to be subdivided into three, fo will the firft ferve for Arrable, the second for Ley Ground, and the third and last for Meadow, if there be any. And if one sheet will not contain the whole, then may you take two. or three, or so many as you fee conveniept., Next you are to take the Plot,' and ge
: neral Survey of the whole, according to the Rules before delivered, and fee if the Sumof all the Particulars agree with the Total, then you may couclude the work is right, but moft commonly the Particulars will somewhat exceed the General Survey; and : in this Case, that both may agree, you are to reduce the Sum of every Mans Par. ticulars answerable to the Proportion of his Ground, which may be effected by the Golden Rule. For, if in the whole Field (which admit it be 1000 Acres) the Particulars exceed the General Survey 3 A cres, what fhall 20 Acres? the Answer will be, 8 Perches, and so much I am to deduct out of the Sum,
Total of such a Mans Particulars, according to which I am to Plot him 19 Acres 3 Roods, 32 Perches. And so of thee reft.
