A49269	Geodæsia, or, The art of surveying and measuring of land made easie by plain and practical rules, how to survey, protract, cast up, reduce or divide any piece of land whatsoever : with new tables for the ease of the surveyor in reducing the measures of land : moreover, a more facile and sure way of surveying by the chain, than has hitherto been taught : as also, how to lay-out new lands in America, or elsewhere : and how to make a perfect map of a river's mouth or harbour : with several other things never yet publish'd in our language / by John Love ...	Love, John, fl. 1688.	1688 (1688)	Wing L3191; ESTC R1523	85,385	310

in your Field-Book the length of any Line you may set it thus if you please with a Stop between the Chains and Links as 15 Chains 15 Links 15.15 or without as thus 1515 it will be all one in the casting up Of Instruments for the taking of an Angle in the Field There are but two material things towards the measuring of a piece of Land to be done in the Field the one is to measure the Lines which I have shewed you how to do by the Chain and the other to take the quantity of an Angle included by these Lines for which there are almost as many Instruments as there are Surveyors Such among the rest as have got the greatest esteem in the World are the Plain Table for small Inclosures the Semicircle for Champaign Grounds The Circumferentor the Theodolite c. To describe these to you their Parts how to put them together take them asunder c. is like teaching the Art of Fencing by Book one Hours use of them or but looking on them in the Instrument-maker's Shop will better describe them to you than the reading one hundred Sheets of Paper concerning them Let it suffice that the only use of them all is no more or chiefly at most but this viz. To take the Quantity of an Angle Plain Table Place the Table already fitted for the Work with a Sheet of Paper upon it as nigh to the Angle A as you can the North End of the Needle hanging directly over the Flower de Luce then make a Mark upon the Sheet of Paper at any convenient place for the Angle A and lay the Edge of the Index to the Mark turning it about till through the Sights you espy B then draw the Line AB by the Edge of the Index Do the same for the Line AC keeping the Index still upon the first Mark then will you have upon your Table an Angle equal to the Angle in the Field To take the Quantity of the same Angle by the Semicircle Place your Semicircle in the Angle A as near the very Angle as possibly you can and cause Marks to be set up near B and C so far off the Hedges as your Instrument at A stands then turn the Instrument about 'till through the fixed Sights you see the Mark at B there screw it fast next turn the moveable Index 'till through the Sights thereof you see the Mark at C then see what Degrees upon the Limb are cut by the Index which let be 45 so much is the Angle BAC How to take the same Angle by the Circumferentor Place your Instrument as before at A with the Flower de Luce towards you direct your Sights to the Mark at B and see what Degrees are then cut by the South End of the Needle which let be 55 do the same to the Mark at C and let the South End of the Needle there cut 100 substract the lesser out of the greater the remainder is 45 the Angle required If the remainder had been more than 180 degrees you must then have substracted it out of 360 the last remainder would have been the Angle desired This last Instrument depends wholly upon the Needle for taking of Angles which often proves erroneous the Needle yearly of it self varying from the true North if there be no Iron Mines in the Earth or other Accidents to draw it aside which in Mountainous Lands are often found It is therefore the best way for the Surveyor where he possibly can to take his Angles without the help of the Needle as is before shewed by the Semicircle But in all Lands it cannot be done but we must sometimes make use of the Needle without exceeding great trouble as in the thick Woods of Jamaica Carolina c. It is good therefore to have such an Instrument with which an Angle in the Field may be taken either with or without the Needle as is the Semicircle than which I know no better Instrument for the Surveyors use yet made publick therefore as I have before shewed you How by the Semicircle to take an Angle without the help of the Needle I shall here direct you How with the Semicircle to take the Quantity of an Angle in the Field by the Needle Screw fast the Instrument the North End of the Needle hanging directly over the Flower de Luce in the Chard turn the Index about till through the Sights you espy the Mark at B and note what Degrees the Index cuts which let be 40 move again the Index to the Mark at C and note the Degrees cut viz. 85. Substract the Less from the greater remains 45 the Quantity of the Angle Or thus Turn the whole Instrument 'till through the Fixed Sights you espy the Mark at B then see what Degrees upon the Chard are cut by the Needle which for Example are 315 turn also the Instrument till through the same Sights you espy C and note the Degrees upon the Chard then cut by the Needle which let be 270 substract the Less from the Greater as before in working by the Circumferentor remains 45 for the Angle Mark if you turn the Flower de Luce towards the Marks you must look at the Norh end of the Needle for your Degrees Besides the Division of the Chard of the Semicircle into 360 Equal Parts or Degrees It is also divided into four Quadrants each containing 90 Degres beginning at the North and South Points and proceeding both ways 'till they end in 90 Degrees at the East and West Points which Points are marked contrary viz. East with a W. and West with an E because when you turn your Instrument to the Eastward the End of the Needle will hang upon the West Side c. If by this way of division of the Chard you would take the aforesaid Angle direct the Instrument so the Flower de Luce from you 'till through the fixed Sights you espy the Mark at B then see what Degrees are cut by the North End of the Needle which let be NE 44 next direct the Instrument to C and the North End of the Needle will cut NE 89 substract the one from the other and there will remain 45 for the Angle But if at the first sight the Needle had hung over NE 55 and at the second SE 80 then take 55 from 90 remains 35 take 80 from 90 remains 10 which added to 35 makes 45 the Quantity of the Angle Moreover if at the first Sight the North End of the Needle had pointed to NW 22 and at the second NE 23 these two must have been added together and they would have made 45 the Angle as before Mark if you had turned the South part of your Instrument to the Marks then you must have had respect to the South End of your Needle Although I have been so long shewing you how to take an Angle by the Needle yet when we come to Survey Land by the Needle as you shall see by and by we
