THE PRACTICAL GAUGER: BEING A Plain and Easy Method OF GAUGING ALL SORTS OF Brewing Vessels. Whereunto is added, A SHORT SYNOPSIS OF THE Laws of EXCISE. By JOHN maine. London, Printed by W. G. for N. Brooke, at the Angel in Cornhill. 1676. To the Honourable PEREGRENE BERTIE, ESQUIRE. May it please Your Honour, MY present Service is so much the more valuable to me, since I was preferred thereto by Your Recommendation, which I shall endeavour to preserve with unwearied Industry and constant Fidelity. Your Favour, Sir, is a Blessing my Soul is too narrow to enclose, and me thinks I can hardly be reconciled to that Divinity which calls Pride a Sin. But if I am guilty, I heartily beg Your pardon, and permission to subscribe, YOUR HONOURS Most humbly devoted Servant, john maine. To the Worshipful PETER CALVERD, SAMUEL VINCENT, EDMUND BOSTOCK, JOHN PARSONS, And RICHARD BRET, ESQUIRES, FARMERS of His Majesty's Revenue of EXCISE within the Kingdom of England, Dominion of Wales, and Town of Berwick upon Tweed; john maine Wisheth Increase of Happiness here, and everlastingly hereafter. To the Reader. HAving been commanded by my Masters into the Northwest Parts of this Kingdom, I found there many ingenious Men, employed in their Service, viz. the Revenue of Excise, which were willing to gain some little knowledge in the Art of Gauging, but had been frighted therefrom by the seeming difficulty of obtaining their desires. I thought it no disservice to endeavour to inform these Men, upon whose shoulders the whole Matter of Fact, in this Affair, between the King and the Subject lay. And accordingly I wrote and read to some of them these short Rules thou hast now before thee, endeavouring to make the Art plain and easy, even to the meanest Capacity, without much expense of Time in reading the Text, or breaking his Teeth with hard Terms of Art: And not having leisure to write so many Copies, as my Friends in those Parts desired, and I could afford them, I am prevailed with to commit it to the Press. Farewell. I. M. THE PRACTICAL GAUGER. IT would be very convenient, that every Gauger were well acquainted with the Art of Decimal Arithmetic; but it is necessary that he be so well seen in Vulgar, as to be able to add, subtract, multiply, and divide any whole Numbers. It is also necessary, that he understand the three sorts of Quantity, viz. a Line, a Superficies, and a Solid. A Line hath length, but no breadth. A Superficies hath length and breadth, but no depth. A Solid hath length, breadth, and depth. Moreover there is no kind of Quantity but is commensurable by some Common Measure thereto assigned, as a Line by a Line of Inches, Feet, Poles, Furlongs, etc. and a Superficies by a Superficies, as the Square Inch, etc. and also a Solid by a Solid: So when it is known how many Inches, Poles, or Furlongs is contained in any Line, the length of that Line is said to be known; and when it is known how many square Inches, square Feet, or square Perches are contained within any Superficies, the Content or Area of that Superficies is said to be known; and also when it is known how many solid Inches are contained in any Solid, the Content of that Solid is known. To find the Content of a Back in the form of a Square or Parallelogram. The Rule is: Multiply the length by the breadth, and the Product divide by 282 (the number of solid Inches contained in the Ale Gallon) and the Quotient is the Ale Gallons contained upon one Inch in depth of that Back or Tun. A Square. An Oblong or Parallelogram. One contains 10 Gallons, and 205/282 parts of a Gallon; the other 21 Gallons and 128/282 of a Gallon. To reduce which Fraction into Pints, you need only multiply the Remainder or Numerator by 8, and divide by the old Divisor, and the Quote will be the Pints contained in that Fraction. To find the Area or Content of one Inch of a Back or Tun, in the form of a Triangle, in Ale Gallons: The Rule is: Multiply the Line a c (viz. the Line falling perpendicularly from any Angle on its opposite Base) by half the Line b c d, hear the Base, and the Product divide by 282, the Quotient will be the Ale Gallons contained in one Inch of depth upon that Triangle. Example. There is contained in the first Inch of this Back or Tun 63 Ale Gallons, 6 Pints, and above an half. But admitting the Back or Tun be of an irregular Form, divide it into Triangles, and let fall Perpendiculars in each, and find their several Area's, as in the last Example, then add them together, and you have the Content or Area of the whole Figure. Example. First I find the Triangle able. Now in the other two Triangles, the two Perpendiculars falling upon one common Base, I multiply the Sum of the Perpendiculars by half the Base, and that Product is the Area or Content of both Triangles. So doth one Inch of this Back or Tun appear to contain of Ale Measure, 9 Barrels, 3 Firkins, and 3 Gallons. Here Note, That formerly the Ale Gallon was accounted to contain 288 ¼ Cube Inches; but by the care and pains of my good Friend, Mr. Nicholas Gunton, the just quantity of the Quart, remaining in the hands of the Chamberlains of His Majesty's Exchequer, appears to be 70 ½, as some of late have found to their no small cost. And I am of opinion, that if the Wine Gallon were carefully examined, it would prove to contain less than it is commonly holden to do, by so much as would improve the Revenue of the Crown some thousands per annum. Now having showed thee how to find the superficial Quantity of any Figure enclosed or bounded by Right Lines, if the Dimensions be alike above and below, multiply the Area by the Depth and you have the Content of the whole; or by any part, and you will find thereby the Solidity of that part. But if the Dimensions above and below be unequal, take your Dimensions or cross Diameters at every Foot or half Foot, and so find the Solidity. Of a Circle. A Circle is a Figure contained or bounded by one Line, which is called the Circumference, as the Line abgd. Within which Line there is a Point, from whence all Lines drawn from the Circumference are equal: And that Point is called the Centre, as the Point c: And through which all Right Lines drawn from one side of the Circumference to the other divide the Circle into two equal parts, and that Line is called the Diameter, as the Line a c b; and the two parts of the Circle, divided by the Diameter, are called Semi●circles, as the part a c b g or a c b d. And although there is not yet found any true proportion between a Square and a Circle, (a Square Inch being our Common Measure) yet is there an Approximation found by Vanculen, which comes almost infinitely near the truth, being as Unity to 3.14159 etc. to the Square of the Semi-diameter. But the old Proportion comes near enough for common practice, viz. As 14 to 11, so is the Square of the Diameter to the Area in Square Inches, etc. Example. Which Area in Square Inches divided by 282 quote the Ale Gallons contained in one Inch of depth in that Circle, or by 231 the Wine Gallons. Example. But I would advise my young Gauger not to trouble himself with the Inches, his business being to find the Gallons the shortest way he can: In order whereunto, let him observe the following Rule. Having the Diameter of a Circle in Inches, to find the Area or Content in Ale or Wine Gallons. The Rule. Square the Diameter (viz. multiply it by itself) and that Square or Product divide by 359 for Ale, and 294 for Wine, and the Quotes will be the Ale or Wine Gallons respectively, that shall be contained in a Circle of that Diameter, and one Inch in depth. If the Tun be in form of a Cylinder, viz. like the Rolling-stone of a Garden, the Circles above and below of equal Diameters, then to find the Content of that Tun, or any part thereof, you need only find the Area of the Circle, and multiply by the whole Depth, or such part as you desire, and the Product will be the Solidity of the whole, or part, respectively. Diameter ab or cd = 80 Inches, the Area before found to be 17 gallons 6 pints, and the Depth = 40 Inches: To find the Content. The Content of this Tun in Beer Measure. But if your round Tun have unequal Dimensions above and below, it is then taken to be the part of a Cone or round Pyramid, having the top cut off as the following Diagram; the whole Cone = abcdefg, the part or Frustum = abcdeg. Having the two Diameters and Depth of the Tun, to produce the whole Cone the Rule is by Proportion thus: As the Semidifference of Diameters is to half the Diameter at the Base: So is the height of the Frustum to the Cones whole Axis. Admit ab 80, cd 140, egg 50, then is the Difference 60, half the Base 70. Example. Having all these Dimensions, the Content of the Tun is not hard to be found. For if you find the Area of the Base, and multiply that Area by ⅓ of the Altitude, or ⅓ of the Area by the whole Altitude, the Product is the Solidity of the whole Cone. Then having found the whole Cone, find also the lesser Cone, and subduct that from the greater, the Remainder will be the Content of the Frustum. Or if you would find the Content of the Frustum, without producing the whole Cone, The Rule is: Multiply the Sum of the two Diameters by itself, then multiply the two Diameters by each other, subduct the lesser Product from the greater, and the Remainder multiply by the depth, the last Product divide by 1077, and the Quote is the Ale Gallons contained in that Tun. The Content appears to be 1727 Ale Gallons, or 47 Barrels, 3 Firkins, 8 Gallons. If it be desired in Feet or Inches, you may find all the Differences of the Diameters, at every Foot, half Foot, or Inch, by this Proportion: As the whole Depth, is to the Difference of Diameters: So is any part of the Depth, to its respective difference of Diameter. Then by Addition or Subduction, you have the Diameters all the way upward or downward. Or, if you please, you may take the Diameters actually, in the midst of every Foot or half Foot, and seek its Area in the Table of Area's hereto annexed, which Area multiplied by the Foot or half Foot gives the Solidity accordingly, without any sensible error. This way I would oblige the young Gauger to, if he be not ready at Proportion. Example. All these Mean Diameters cut this Tun into so many Cylinders. Now having the Area of each Circle, which is an Arithmetical Mean of the half Foot, multiply this Area by 6, and the Product is the Solidity of that half Foot. This Tun cast up by the Rule, pag. 19 Whereby appears not a Gallon difference. If the Conjugate or Cross Diameters above and below are not equal, then do Geometricians call that Tun Eliptical; to reduce which to a Circle, there ought to be a Geometrical Mean taken, but the common practice is to add them together, and take the half, which if the Diameters differ not much, the error is the less. Coppers are commonly taken at every 6 Inches, as that Tun in pag. 21. To find the Content of a Coppers Crown, take this Rule: Square the Diameter at the Base, to this add 4/3 of the Square of the Crowns Altitude, the Sum multiply by the Altitude, the last Product divide by 718, the Quote is the Ale Gallons contained in that Crown. To find the Content of the Mash Tun, in Quarters, Bushels, and Gallons, there can be no certain Rule in taking the Depth of the Goods, by reason of the difference in the goodness of Malt, some spending itself much more in the wetting than other; yet that considered, there may be some estimate given thereto, whereby a very considerable fraud may be discovered. In a square Mash Tun, divide the Product of the Length and Breadth by 227 for indifferent, or by 200 for the finest, and the Product will be the Gallons wetted; and for round Mash Tuns, let your Divisors be 288 or 260, respectively. For Cask-Gauging, wholly full, I have given many Precepts and Examples in a Treatise called The Merchant's Companion, Printed about a year since; but that the Reader may not be left here wholly without, take the following Rule, which considers the Cask as the Frustum of a Spheroid, that being the most general form. To find the Content of a Cask in Ale or Wine Gallons. The Rule. To the doubled Square of the Boung Diameter add the Square of the Head Diameter, and that Sum multiply by the Casks Length, the last Product divide by 1077, and the Quote is the Ale Gallons, or by 882 quotes the Wine Gallons contained in that Cask. Example. The Content of this Cask is 73 Ale Gallons, 2 Pints, and almost an half. Or, by the Table of Area's, thus: To twice the Area of the Boung Circle in Gallons and parts add the Area of the Head Circle, the Sum of these multiply tby ⅓ of the Casks Length, and the Product is the Content in Gallons and parts, as in the former Example. Which Fraction being reduced is 2 Pints and better, as was before found. A TABLE OF Area's of CIRCLES IN ALE GALLONS AND MILESIMAL PARTEST To every Quarter of an Inch, From 1 to 12 Foot of Diameter.

Example. Thus may be made any Number, greater or lesser than the Table doth exhibit, the difference here being not 1/1000 part of a Gallon. To make a Table of ⅓ ds of Area's of Circle's in Wine Gallons, The Rule is: Multiply ⅓ of the Square of the Diameter by .0034, or multiply the whole Square by .0034 and the Product divide by 3; and the Product of the former Work, or the Quotient of the latter, is the Circles Area.

Example. To find the Content of a Cylinder, whose Diameter is 38, and Depth 4 Inches. I first seek the Diana. 38, and against it in the Column under 4 I find 16.08, which is 16 Gallons and 8/100 parts.

FINIS. A SHORT SYNOPSIS OR INDEX OF THE LAWS OF EXCISE. LONDON: Printed by William Godbid, 1676. The Use of the precedent Table is very considerable in Geometry, but my present intention is to apply it to Cask-Gauging, viz. To find the vacant Frustums in a Cask partly full, lying with its Axis parallel to the Horizon, the Cask being taken as the Frustum of a Spheroid cut with two Planes parallel, bisecting the Axis at Right Angles. And here it is requisite, the Boung and Head Diameters, Casks Length, the whole Content, and dry or wet Inches be known. Then, if the Question be what is wanting, or what is remaining in the Cask? divide either the dry or wet Inches by the Boung Diameter, and the Quote seek in the Table, under V or Versed Sine, against it stands a number, which multiplied by the Content exhibits the Vacuity, if your Dividend were the dry, or the remaining Liquor, if it were the wet Inches. Some Examples of the Use of this Table of Area's of Segments, in finding the Vacuity of Cask. QUEST. I. What is the Vllage of a Cask, whose Boung Diameter is 28 Inches, Content 60 Gallons, and dry Inches 7? According to the precedent Rule, I divide 7 by 28, which I do by adding two Ciphers, thus: Then seeking 25 in the Table in the Column under V, in the next Column against it I find .1955, which number I multiply by the whole Content, and cutting off four places toward the right hand of the Product, it exhibits the Ullage or Wants in that Cask in Gallons and parts. Example. So is the Ullage or Wants 11 Gallons and almost ¾ of a Gallon. QUEST. II. What quantity of Liquor is there remaining in this Cask? Divide the wet Inches by the Boung-Diameter, after this manner: Against which number (75) I find in the Table .8045, which I multiply by the whole Content as before, and the Product gives the quantity of remaining Liquor. Example. Now if after Division there happen a Remainder, and that be above half the Divisor, I take the next bigger number; or if it be less than half the Divisor, I take the next lesser number, as in the following Examples. QUEST. III. If in the forementioned Cask there be 9 Inches of the Boung Diameter dry, what is the Wants? Here the Remainder being under half the Divisor I take 32, QUEST. IV. There being 19 wet Inches, what is the remaining Gallons? Here the Remainder being above half the Divisor, I take the next bigger number, viz. 68, THE DESCRIPTION AND USE Of the GAUGING-RULE. THE DESCRIPTION & USE OF THE GAUGING-RULE. THis Rule is commonly four Foot in length, and is made to double in four joints, for convenient portage: It hath also four Sides, on which are drawn several Lines, viz. 1. There is two Lines called Diagonals, the one for Wine, the other for Beer or Ale-measure. These are so commonly known, that I suppose there are few Officers but are well acquainted with them; however, lest any should be ignorant, take this following advice. Put the end which is cut slope-ways in at the Boung-hole, and let i● touch the bottom of the Head, the Number that appears at the Boung is the Number of Ale or Wine Gallons respectively. As for Example. a Cask. Put your Rule down at the Boung-hole e to the bottom of the Head c, if 60 appear at the Boung on the Diagonal for Wine, then is the Content 60 Wine Gallons, and almost 49 Ale Gallons, for the Sub-divisions between the Numbers from 10 upwards signify each one Gallon. This way will give a very good estimate of the Content of all Cask, in ●he form of the London Beer Barrel, or the French wine Hogshead. These Lines being together serve also very well for a Table of Reduction of Wine into Ale measure, and the Converse, by inspection only. 2. On another Side or Face there is put a Line of Inches, from 1 to 48 Inches, and each decimally divided; and also upon the same Side you have Oughtred's Gauge-Line, it being a Line of One thirds of Area's of Circles, in Wine Gallons, by which you may Gauge a Cask after this manner: Put your Rule down at the Boung perpendicularly, observing what Number appears j●●t even with the inside of the Cask, admit it be 7, set that down twice, then take the Diameter at the Head, and let that show you 6 upon the same Line, set that down to the former, add these three Numbers together, and multiply the Sum by the Casks Length, here 30, then cut off one place from the Product toward the right hand, and the Figures toward the left hand are your Number of Wine Gallons contained in the Cask. Example. Note, If your Diameter fall amongst the Divisions, between the Numbers, you must cut off two places from the Product. Example. Content as before 60.00 Wine Gall. 3. On a third Face of this Rule (which meets the precedent Line of One thirds of Area's upon one Angle or Edge of the Rule) is put a Line of equal parts, numbered from 1 to 96, and is divided into halves: This Line considered together with that before mentioned, do make a Table of Area's of Circles in Ale Gallons, so that if you find your Diameter in this Line, turn up the other Face, and against your Diameter you shall have the Area of your Circle in Ale measure. As for Example: The Diameter of a Circle is 19 Inches, the Area of that Circle upon the other Edge in Oughtrea's Line is a little above one Gallon. Again, the Diameter being 30 Inches, the Area is 2.5 Gallons; and if the Diameter be 67 Inches, it holds 12.5 Gallons upon one Inch of depth. The Use of these Lines, thus together, is the same with that of the Table of Area's page 29, etc. 4. On the fourth Side of this Rule is drawn a Line of Numbers, vulgarly called Gunters' Line, which Line with a pair of Compasses is of excellent use upon sundry occasions, it being a Line of Logari●hms, and by it is performed Multiplication, Division, Extraction of the Square and Cube Roots, and many other Calculations Arithmetical: Of this Line alone, are two or three Books of like magnitude with this already printed, to which for those things I r●fer you, and sh●ll here only apply it to Cask-Gauging; of which take the following Instructions: First learn to find any Number upon the Line; from 1 to 10 you have the Figures Arithmetically placed, and the subdivisions are tenths; but from 10 to 20 the divisions signify each an additional Unite, and so to 100 At 17.2 you have a small brass Pin, whereon to set the Foot of your Compasses, and is called the Gauge-point for Wine Gallons, almost at 19 is the Gauge-point for Ale Gallons, the first hath w g, and the other a g placed over it, by which they are easily known. To Gauge a Cask by this Line, you must first find the Diameter at the Head and Boung, and also the Casks Length, by the Line of Inches: These being had, find your mean Diameter, by adding double the Boung Diameter to once the Diameter at the Head, and divide their Sum by 3, the Quote take for your Mean: Then with your Compasses set one Foot in the Gauge-point, and extend the other to the mean Diameter upon your Line of Numbers, so keeping your points at that distance, set one Foot at the number expressing the Casks Length, and from thence double the distance of the Feet of the Compasses exhibits the Content in Ale or Wine Gallons respectively. As for Example: A Cask, Boung Diameter 27, Head 24, Length 30 Inches, if the Content be required in Ale or Wine Gallons, I find the mean Diameter according to the Rule thus: The mean Diameter being 26, I take my Rule and Compasses, if the Question be Ale Gallons, and set one Foot in the Gauge-point for Ale, and the other I extend to 26, than I take off the Compasses so extended, and setting one Foot at 30, the Length, giving the Compasses one turn upon the other Foot, whereby to take the double distance, and the point toucheth at 57, which is the Content of that Cask in Ale Gallons. If the Question be Wine Gallons, I take the distance from the Gauge-point for Wine to 26, the mean Diameter, and the Compasses applied to the Casks Length, and turned as before, exhibits 69, the Content of the Cask in Wine Gallons. This is a very quick and easy way of Gauging Cask, and is also an approximation near enough the truth for common practice. Having the mean Diameter of any Conical Tun, and the Depth of Liquor, the Quantity is found after the same manner. Example. The mean Diameter of a Tun 28, Depth of Liquor 29, Quantity of Ale Gallons will be found 63 ½. The common way of finding the mean Diameter of a Conical Tun, is by adding the Diameters above and below together, and take the half. This I allow, as an easy and practical way for young Gaugers; but note, that the greater the difference of the Diameters are, the greater is your error, but in Diameters that differ not much, it doth very well. There is also another Line, that runs parallel with this Line of Numbers, and is called a Line of Segments, but I like not the Hypothesis upon which it is framed, and the way of finding the Wants of a Cask (lying with its Axis parallel to the Horizon, being partly empty of Liquor) made so plain and easy, by the precedent Example's upon the Table of Area's of Segments, I had thought to have left it out, but lest any having a Rule and not Table by him, should have such occasion, let him take one Example. A Casks Boung 24 Inches, wet 18 Inches, Content 50 Ale Gallons, what is the Ullage or Wants in this Cask? As 24 on the Line of Numbers, is to Radius on the Segments: So is 6 on the Numbers, to 17.8 on the Segments. Then, As Unity, to 50 on the Numbers: So 17.8 on the Numbers, to 8.9 Ale Gallons, the Wants required. FINIS.
