ONE HUNDRED THOUSAND FACTS FOR THE PEOPLE. 419 



Example. — Required the contents of a 

 round stick of timber in cubic feet whose 

 girth in the middle is 84 inches and length 

 25 feet 6 inches: 



84-^-4 = 21 inches }£ girth. 

 f. 1. 

 And 21 inches = 1.9 

 Multiplied by 1.9 



1.9 

 '♦3-9 



= 3.0.9 



F. I. 



Then 25.6 

 Multiplied by 3.0.9 



Feet, 78. 1. 1.6 

 But a more expeditious method is ob- 

 tained by means of the following table : 



Rule. — Multiply the area correspond- 

 ing to the ^ girth in inches by the length 

 of the timber in feet, and the product is 

 the solid contents in feet and decimal 

 parts. 



Example. — A piece of timber 18 feet 

 long and 14 inches square, what are the 

 cubic contents in feet ? 



1. 36 1 X 18 = 24.498 cubic feet. 



PLASTEEEES' WORK, MEASURING. 



— Plain plastering is measured by the 

 superficial yard — that is, 3 feet multiplied 

 by 3 feet= 9 feet. 



^ In measuring ceilings, take the dimen- 

 sions from wall to wall. 



In measuring walls and partitions, take 

 the girt around the room for a length, 

 and from floor to ceiling for the height, 

 deducting one half of the openings, such 

 as doors, windows, &c. 



All cornices and mouldings, and all 

 work where the running mould is used, 

 are measured from the nose of the mould- 

 ing to the wall; and we speak of a 

 moulding as being so many inches ac- 

 cording to girt ; the length is taken 

 on the wall line, and one foot lineal is 

 allowed to each metre. Take all plain or 

 moulded cornices under 12 inches girt by 

 the running foot, and all above that girt 

 by the superficial foot. The plain parts 

 of ornamental cornices should first be 

 taken as plain, and the several enrich- 

 ments therein taken per foot run, at their 

 separate values,, which added to the price 

 of the plain moulding, will give the cor- 

 rect value per foot run of the whole 

 cornice complete. 



Mouldings encircling centres, to be 

 measured as mouldings. 



All circular work, double measurement. 



All inclined or raking ceilings under an 

 angle of 22 degrees with the horizon, to 

 be measured as level; over 22 degrees, 

 one and a half measurement. 



Closets and presses under 4 feet by 8 

 feet, double measurement. 



Privies, double measurement. 



Furring, regulating or striping on all 

 lath work at per square. 



Whitening and coloring are measured 

 in the same manner as plastering. 



Niches and arches are valued at so 

 much each. 



Cast and enriched centres to ceilings 

 fixed, &c, complete, so much each, 

 according to diameter. 



All circular enrichments to be twice 

 the price of straight of the same 

 description. 



When enrichments are modeled from 

 original designs, the expense of modeling 

 to be paid for extra. 



Outside work done with cement or 

 mastic, measured same as plastering ; but 

 no openings deducted.
