Geodaesia improved; or, a new and correct method of surveying made exceeding easy in two parts : part I. Teacheth to measure, divide, and delineate, any quantity of land both accessible and inaccessible, whether meadows, pasture, fields, woods, water, commons, forests, manors, &c. by the chain only, whose dimensions are cast up by the pen, and consequently freed from the errors of estimation that unavoidably attend the scale and protractor. With necessary directions to map elegantly : part II. Introduces instruments, trigonometry, preparative remarks on the earth's superficies; and teacheth the invaluable method of casting up the dimensions of instruments by the pen several ways, all agreeing, &c. &c. : with a most useful appendix concerning the practical methods of measuring timber, hay'marl pits, bricklayers and plasterers work... / A.

GEODÆSIA Improved.

The Field wherein you first began, is called the Field M, whichyou must lay down (from any suitable Scale of equal Parti) uponPaper, as you took. it up, viz.

i. Draw a Line with your Dividers of a sufficient Length,then assume a Point therein, as T ; from a Scale of equal Partstake 19.50, and lay it from T to A, upon which lay downyour Left-hand Ost-set, as you were directed in the two fore-going Examples, Chapter IX.

L. Having planned this Off-fet, begin with those Dimensionsthat are on the Right-hand Side of the Line T A, and thusproceed:

3. At T erect the Perpendicular C w, and lay thereon 3Chains for your fir st Perpendicular to the Right-hand ; lay down4Chains upon the common Base T A, from T too, and thereatlay down, at Right-angles, your second Perpendicular, namely,8 Chains; also 17 Chains from T; lay off your third Perpen-dicular 13 Chains, which will point out the South-East Cor-ner of this Field; with your Pencil join T w and m together,which Line will represent the West Hedge.

4. Draw a Line from the Corner B, to the Corner A, asa base Line for your East Off-fet, and lay thereon 6 Chains,at which Place lay off your Perpendicular 15 Chains, then withjour Pencil join A d and B, for the East Side of the Field.

5. Draw a Line from B to m, and in like Manner lay thereonyour South Off-fet, as above directed, and,

Lastly, with your Pencil draw a Line through m B, and theextreme Points of the several Perpendiculars raised upon thatLine, so shall you have the South Side of the Field represented.The Form of the Field being thus plotted, you may easilytrace the Boundaries thereof with a drawing Pen and Ink.

The next you entered was Q_, Pools Meadow, which t*plan, proceed thus:

i. With 2o.io Chains in your Dividers, and setting one Leg inm, describe an Arch, and from your Scale take 10.50 Chains also
