meane and so is of little or no variation and the variation to bee of his declination and the imperfection of the eye wherein yet I rest vnder reformation The nedle neere London seemeth to decline his north point about 71. degrees vnder the north Pole consequently eleuateth his other point aboue the south Pole And this groweth by reason of the rotunditie of the earthes globe about which as the nedle is moued it keepeth his pointes as it were parrallell with the horrizon in that it is equally ballanced in his boxe and so the weight countermaundeth the vertue of the stone and forceth the nedle to cut euery line that commeth to his Centre from the centre of the earth C. by ryght angles as EEEE in the figure do shew But if it coulde bee placed in the earthes center C. they thinke it would haue no variation at all when it commeth vpon the line of the Poles D D. it cutteth the same also by equiangles and then are the nedles pointes forced to stand meerelie contrary to the Poles And there seemeth a mortificatiō of the nedles vertue which staggereth vncertainely being by his waight preuented of eleuatinng his point to the desired obiect which vnder correction I take to be the Pole though M. Normā most skilful wil haue a respectiue rather then an attractiue point but it seemeth rather an attractiue then a meere respectiue by reason of the nedles attraction of Iron or steele massie bodies The figure Now whether it bee fittest to obserue this variation in the description of a particular countrey I will incounter no mans probable reasons yet in my simple iudgement the nedles direction is to bee followed meerely without allowance of ●ny variation for that it giueth the magneticall meridians without scruple by which the worke is protracted though they seeme to varie from the Polar meridians And that direction of the nedles respection I take more certaine then the variation in asmuch as the nedles true variation in euery small distance is not so easily certainely found though through the most industrious trauailes and studies of the learned M. D. Hoode M. Burrowes and others there are extant to the ease of practitioners most necessarie inuentions for the same to whose learned censures I subiecte my conceit Many Surueyours and plotters of land seem to haue a speciall curiosity in obseruing this variation of the compasse by some of whom I haue beene persuaded to follow the same also But for two causes I couet to be farther resolued of the necessity thereof before I can bee thereunto induced The first and principall is for that who so hath his variation allowed at and according to the declination and meridian of London going farre west or farre North to put the same in practise by that variation shall erre And to obserue it in euerie place he can hardly at all times And therefore it seemeth more troublesome and doubtfull then of importance A second cause is for that a special consideration is to be had in a suruey of the buttes and boundes of land and to shape them as neere as may be according to the auncient limitations for that they may els make a differēce between the antique and their moderne obseruations which were laid out without variation of the Compasse nay without Compasse at all for the most parte onely by the sunnes noone steed which directed the south and thence the three other principall pointes were deriued East West and North as appeareth by the figure following By this figure it may appeare that a bounde which our fathers placed according to the ancient manner easterly may by this new rule of variation which is 11. degrees 15. minutes at London from the former receyued pointes become southerly or appeare doubtfull and so of the rest of the points whereby may grow to posteritie in intricate thinges cause of iustifiable controuersie yet whosoeuer findeth in his discretion no reason but to follow the variation Fiat cuiusque voluntas For my part as I thinke it needles to follow any other then the nedles meere direction I will adde therevnto no mans imagination vntill by reason I be satisfied of a necessitie therein and then I will not be obstinate I haue not represented my meaning by the former figure as imagining any professour ignorant of the matter but that the demonstration duely considered may worke more in some conceites then a bare speculation 2 For the obseruation of longitude latitude in euery particular Shire is not materiall as I take it for that few Shires wil admit one degree some not 30. fewe 40. minutes And therefore to refer that obseruation to the general Mappe of the whole land 3 As touching the reducing of euery Shire into one equall Scale howsoeuer it may seeme to please some it wil not agree with the opinions of the most for that some Shires of the greatest magninitude will require two sheetes of paper Royall when some other will not containe ¼ of a sheete And therefore I take it better to admit equall proportion in magnitude then equalitie of Scale 4 Such as would haue the true obseruation of the miles to answere some certaine content haue reason to propounde it I confesse But such as haue but speculation in the Arte much more such as are practisers howsoeuer easie it bee deemed by geometricall theoremes to bee performed as in deede it is yet by practise they do or may find such a difficultie in the accomplishing thereof exactly as doth straine euen the mechanicall conclusions beyond that which is required in plotting of land which by application of the line or rod may bee performed by the instrument without intersecting of lines which this work requireth And the better able more skilfull then my selfe wold with me acknowledge vpon proofe that the absolute performance of such an expected geographicall description after such proportion of miles as may bee propounded doeth require dimensuration betweene euery station aunswerable to the measure propounded that by the intersecting lines the distances may bee gathered according to the same proportion And so many stations of necessitie ought to be as the obscurity of the places whose viewe is often intercepted by woodes mountaines c may in arte require which are so infinite and intricate vnlesse in open leuell as to obserue them singularlie and precisely will require the whole time of a mans ripe yeares to effect the description of England Hoc patet expertis But if there were an instrument that would giue any farre distance at one station without dimensuration it were to be performed with more facilitie Such an instrument I knowe in some measure may be effected that woulde yeeld some little distance founde true by Arithmeticall geometricall probation nothing seemeth defectiue therein as touching these artificiall conclusions onely the sightes impediment bewrayeth imperfection of the instrument Such an instrument I haue heard M. Blagraue hath effected such a one hath beene promised by
