distance, not exceeding one mile, 3s. per cubic 

 yard. — Scotch prices from Id. to l^d. less. 



Plain-tiling. — 760 tiles to 3^ gauge, 5 hods of 

 mortar, 500 of 4 lb. nails, 1 bundle of fir laths, 

 1£ inch by £ inch, (500 feet in length,) and 1 peck 

 of tile-pins, are sufficient for one square (100 

 superficial feet) of roofing ; and the cost 42s. for 

 all materials, 15s. 6d. for all but tiles, 10s. 6d. for 

 lime and labour only, and 6s. for labour only. If 

 oak laths are used, add for the two first 2s., and 

 the two last 6d. per square. 



Pan-tiling. — 165 pan tiles, 120 of 6d. nails, 

 1 bundle (or 500 feet in length) of laths 1^ 



inch by 1 inch, are sufficient for a square of 100 

 superficial feet ; and the expense, if laid dry to a 

 10-inch gauge, 23s. for all materials, &c, 9s. 6d. 

 for all but tiles, 3s. 6d. for lime and labour only, 

 and 3s. for labour only. — The above are London 

 prices. Scotch prices nearly 25 per cent less. 



In measuring brick-work, multiply the super- 

 ficial face of the wall by the number of half 

 bricks it is thick, which will reduce it to half- 

 brick work, and divide that sum by three, which 

 will reduce it to brick-and-half work, or standard 

 thickness ; dividing this by 272, the exact quan- 

 tity in rods will be given.

By this measure all things having length and 

 breadth are measured and calculated. 



In England, carpenters measure their flooring, 

 sarking of roofing, &c, by the square containing 

 100 square feet. Slaters , particularly in England, 

 adopt the same rule; while in Scotland both 

 slaters and carpenters in general measure by 

 the rood of 36 superficial yards. 



Masons, bricklayers, painters, glaziers, and 

 often slaters, calculate by the rood of 36 square 

 yards ; the two latter also by the square foot or 

 square yard. 



The Scotch chain, like the imperial one, 

 consists of 100 links, and is generally reckoned 

 to have been 74 imperial feet in length, but was 

 in reality 74.1196 feet. 5760 square ells— 160

falls — 10 square chains — 4 roods — 1 acre ; equal 

 to 1.261183 imperial acre. 23 Scotch acres 

 make about 29 imperial; or, more nearly, 134 

 Scotch are equal to 169 imperial acres. 



To reduce Scotch acres, therefore, to impe- 

 rial ones, multiply by 1.261183. 66 feet make 

 1 imperial chain. 



SOLID MEASURE. 



1728 cubic inches make 1 cubic foot ; and 

 27 cubic feet one cubic yard. 



By this measure all excavations of earth, 

 stones, gravel, &c, are calculated; as well as 

 timber in logs, &c. ; stone, marble, &c, in 

 blocks.
