EXAMPLES.

What will the Paving of a Street come to at 6d. per Yard, the Length of the Street being 176 Feet, and the Breadth 563 Feet?

(6) What is the Content of a Piece of Wainscoting in Square Yards, that is 94 Feet in Height, and 84 Feet broad? and what will it come to at 6s. per Yard? (7) There is a Room 84 Feet round, and 9 Feet 6 Inches high, in which are three Windows, each 6 Feet high and 3 Feet 5 Inches wide, and the Fire Place 4 Feet by 4 Feet. I demand how many Yards of Paper, Half Yard wide, will hang it? (8) If my Court-Yard be 47 Feet 7 Inches square, and I have laid a Footway of Purbeck Stone 4 Feet wide, along one side of it, what will paving the rest with Flints come to at 6d. per Yard square?

(9) A rectangular four-sided Room measures 129 Feet about, and is to be wainscoted at 3s. 6d. per Yard square; after the due Allowances for Girt of Cornice and Member, it is 16 Feet high; the Door is seven Feet by 34 Feet; the Window Shutters, two Pair, are 74 Feet by 4 Feet; the Check Boards round them come 14 Foot below the Shutters, and are 14 Inches in Breadth; the lining Boards round the Door-Way are 16 Inches broad; the Door and Window Shutters, being wrought on both Sides, are reckoned Work and Half, and paid for accordingly; the Chimney 33 Feet by 3 Feet, not being inclosed, is to be deducted from the superficial Content of the Room and the Estimate of the Charge is required?

(10: What will Plastering of a Ceiling, at 10d. per Yard, come to, supposing the Length 344 Feet, and the Breadth 20 Feet?

(11) There is a Quantity of Partitioning that measures 34 Feet 8 Inches about, and 144 Feet high; but is rendered between Quarters: the Lathing and Plastering will be Sd. per Yard, and the Whiting 2d. per Yard. What will the Whole come to? Note. In measuring Plastering; rendering between Quarters, ther is commonly a fifth Part of the whole Area deducted; but when rendering between Quarters is whited or coloured, there is commonly a fourth or fifth

Part added to the whole Area, for the Sides of Quar ters and Braces, &c.

III. FLOORING, PARTITIONING, ROOFING, TILING, &C. is measured by the Square of 100 Feet.

IN these Measurements the Dimensions are taken by a Rod of ten Feet long; and therefore the Result is in squares of 100 square Feet each.

Hence, dividing the Area in square Feet by 100, the Quotient will be the Number of Squares required.

EXAMPLES.

(12) In 120 Feet in Length, and 124 Feet in Height of Partitioning, how many Squares?

(13) What Difference is there between a Floor 28 Feet long,

and 20 broad, and two others that measure 14 Feet a-piece by 10? and what do all three come to, at 21. 5s. per Square?

(14) Suppose a House of three Stories besides the GroundFloor, was to be Floored, at 81. 10s. per Square; the House measures 30 Feet by 20 Feet; there are eight Fire Places, whose Measures are four of 6 Feet by 54, and four of 44 Feet, by 4, and the Well-Hole for the Stairs is 10 Feet by 84; what will the Whole come to? (15) How many Oaken Planks will Floor a Room 60% Feet long, and 335 wide, supposing the Plank 15 Feet long, and 14 wide?

(16) Suppose a House measures, within the Walls, 64 Feet in Length, and 36 Feet in Breadth, and to be of a true Pitch; what will it come to Roofing, at 12s. 6d. the Square?

(17) Suppose I employ a Person to thatch a Barn, which is 70 Feet long, and 30 deep; I demand how many Squares are contained in the Whole; also what it will come to at 10s. 8d. per Square?

(18) What will the new Ripping and Out-house cost, that measures 323 Feet long, by 224 broad, upon the Flat, at 15s. the Square; the Eaves' Boards projecting 10 Inches on each Side ?

Note-In Tiling and Roofing, it is customary to reckon the

• Flat and Half of any Building within the Walls to be

the Depth or Width of the Roof of that Building when the said Roof is of a true Pitch, that is, when the Rafters are of the Breadth of the Building. But when the Roof is more or less than the true Pitch, they -measure from one Side to the other.

IV. BRICKLAYERS' WORK is measured by the Rod, of 2721 Square Feet.

THIS Work is always valued at the Rate of a Brick and a Half thick; and if the thickness of the Wall is more or less, it must be reduced to that Thickness by the following

RULES.

1. Multiply the Area of the Wall in Feet, by the Number of half Bricks in the Thickness the Wall is of: divide the Product by 8163, and the Quotient will be the Content in Rods ;-Or,

2. Multiply the Area of the Wall by the Number of half

Bricks the Thickness the Wall is of; the Product, divided by 3, gives the Area in Feet, which divide by 2724; the Quotient will be the Rods required.

Note. The Fraction & in Rule 1, or 4 in Rule 2, is rejected in Favour of the Workmen.

EXAMPLES.

(19) There is a Brick Wall 470 Feet round, and 9 Feet high, and three Bricks thick. How many Rods doth it contain ?

(20) A Gentleman built a Wall round his Garden, which is 840 Feet, and 9 Feet high, and 24 Bricks thick. How many Rods doth it contain, and what will it come to at 4/ 19s 6d. per Rod?

(21) The End Wall of a House is 244 Feet in Breadth, and 40 Feet to the Roof; of which is two Bricks thick, more 14 Brick thick, and the rest I Brick thick. Now the Gable rises 38 Courses of Bricks 4 of which usually make a Foot in Depth), and this is but 4 Inches, or half a Brick thick. What will this Piece of Work come to at 5/ 10s. per Statute Rod?

- Edge must the Line be struck ? (2) Having a rectangular Marble Slab, 58 Inches by 27, I would have a Foot Square cut off, parallel to the shorter Edge, I would then have the like Quantity divided from the Remainder, parallel to the longer Side; and this alternately repeated till there be not the Quantity of a Foot left.

How many of the shorter Rows will there be?
