tliirJ point, an.1 tliere fix the arm CB ; then, bringing the 

 tracer to the left hand feftor, (lide the bevel, keeping tl'.e 

 arms conftnntly be:>ri'ig agninft the two fetors, till it comes 

 to the rit^ht hvmd fedor, by which the requited arc will be 

 defcribed by the motion of its centre C. If the arc be 

 wanted iii fome part of the drawing without the given points, 

 find by cafe i. under /mAA- bccd, other points in tliofe jiavts 

 ■ where the arc is required ; and thus a given arc may be 

 lenc;ti:L-\ied as far as is ncceffary. 



2. To defcribe an arc of a p;ivcn radius, not lefs than 

 ic inches. — Fix the ann CB fo that the part of its edge, 

 toncfpondiiig to the given radius, always reckoned in inches, 

 inav lie over the fun- line drawn on CD for that ptn-pofe ; 

 being the centre to the point through which the arc is re- 

 quired to pafs, and difpofe the bevel in the direction in 

 which it is intended to be drawn; place the feftors G, G, 

 exactly to the divifions loo in each arm, and I'.nke the 

 arc as above defcribed. 



^. The bevel being fet to flrlkc arcs of a given radius, 

 as in the> l>iil inftance, let it be required to draw other arcs, 

 whofe radii (liall have a given proportion to that of the 

 firft arc. Suppofe the bevel to be fet for defcribing arcs 

 of 50 inches radius, and it be required to draw arcs of 

 60 inches radius, with the bevel fo let. Say, as 50 is to 

 60, ft) is the conrtant number 1 30 to 120, the number on 

 the arms CA and CD, to which the fedors mull be placed, 

 in order to defcribe arcs of 60 inches radius. When it is 

 faid that the bevel is fet to draw arcs of a particular radius, 

 it is always underllood that the lectors G, G, are to be 

 placed at N" 100 on CA and CD, when thofe arcs are 

 drawn. 



4. An arc ACB ^_o-. 41.) being given, let it be required to 

 draw other arcs concentric to it, which fliall pafs through 

 given points, e.g. P. Through the extremities A and B 

 of the gis-en arc, draw lines AB, BP, tenduig to its centre, 

 by cafe 3. wnAer fimple bevel. Take the neareil dillance of 

 the given point P from the arc, and fet it from A to P, and 

 froni B to P. Hold the centre of the bevel on C, any point 

 near the middle of the given arc, and bring its arms to pafs 

 tl'.roujh A and B at the fame time, and fix them there. 

 Place the fedtors to the points P and P, and with the bevel, 

 fet as before directed, draw an arc, which will pafs through 

 P' the given point, and be concentric to the given arc 

 ACB. 



5. Through a given point A ff^. 42.) in the given line, 

 to ftrikc an arc of a given radius, and whofe centre (liall 

 lie in that line, produced if necclfary. Set the bevel to the 

 given radius, by cafe 2. Through A, at right angles to 

 AB, draw CD ; lay the centre of the bevel, fet as above, 

 on A, and the arm CA on the line AC, and draw a line 

 AE along the edge CD of the other arm. Divide the an- 

 gle DAE into two equal parts by the line AF, and place 

 the bevel fo that, its centre being at A, the arm CD Ihall 

 lie on AF ; while in this fituation, place the feftors at 

 N" 100 in each arm, and thtn (Irike the arc. 



6. An arc being given, to find tlie length of its radius. 



Place the centre of the bevel on the middle of the arc, 



and open or fiint the anus till N'' 100 on CA and CD, fall 

 upon the arc on each fide of the centre ; the radius will be 

 found on CB (in inches) at that point of it, where it is cut 

 by the line drawn on CD. If the extent of the arc be not 

 equal to that between the two Nos. ico. make ufe of the 

 N^ yO, in which cafe the radius found on CB, will be double 

 of that fought ; or the arc may be lengthened by prob. i. 

 till it be of a f ificitnt extent to admit the two Nos. 100.

BEVEL AND, in Geography, the name of two ifiands,

formed by the feparate branches of the Scheldt, belonging 

 to the ftate of Zealand ; the one, called North BevelancI, is 

 about z leagues long, and i j broad ; it is fouch of Schonen 

 ifland, and on the fouth iide of the channel of the call 

 Scheldt, that here runs into the fea ; the other, called South 

 Bsvf'ji'.tl, or 'Ztihl, is near 8 leagues long, and 2' wide, and 

 comprehends the town of Goes and feveral villages; it di- 

 vides the ea'it from the weft Scheldt, and the two points of 

 its weft end approach to the channels oppofite to the ports 

 of Armuyd and Flufhin^-. Both thefe illands have fufl'ered 

 much from inundations. 



BEVELLING, in Ship Jhii'ding, the art cf hewingtimbcr 

 with a proper and regular curve, according to a mould which 

 is laid on one fide of its furface. 



In order to hew any piece of timber to its proper bevel, it 

 will be very expedient to make one fide fair, and out of wind- 

 ing ; a term ufed to fignify that the fideof the timber fliould 

 be a plane. Now if this fide be uppermoft, and placed ho- 

 rizontally, or upon a level ; it is plain, if the timber is to be 

 hewed fquare, it may be done by a plummet and line ; but 

 if the timber is not hewn fquare, the line will not touch 

 both the upper and lower edge of the piece, or if a fq\iare 

 be applied to it, there will be wood wanting either at the 

 upper or lower fide. This is called within or without a 

 fquare. When the wood is deficient at the under fide, it 

 is called under-bevelling ; and when it is deficient in the up- 

 per fide, it is called flanding bevelling ; and this deficiency 

 will be more or lefs according to the depth of the piece : fo 

 that before the proper bevellings of the timbers are found, 

 it will be fometimes very convenient to affign the breadth of 

 the timber ; nay, in moil cafes, it will be abfolutely necef- 

 fary, efpecially afore and abaft: though the breadth of two 

 timbers, or the timber and room, which includes the two 

 timbers, and the fpace betwixt them, may be taken without 

 any fenfible error, as far as the fquare body goes. For as 

 one line reprefcnts the moulding fide of two timber.;, the 

 forefide of the one being fuppofed to unite with the aft fide 

 of the other, the two may be confidered as one entire piece 

 of timber. For further obfervations on this fubjedt, and 

 particular inflruftions with refpecl to the mode of bevelling 

 by ribband lines, and by water-lines, fee Murray's Treatife
