1. To make deductions for chimneys, windows, and doors.
2. To make deductions for rendering upon brickwork, fordoors and windows.
3. If the workman find materials for rendering betweenquarters, one-fifth must be deducted for quarters ; but ifworkmanship only is found, the whole must be measured aswhole work, because the workman could have performed thewhole much sooner, if there had been no quarters.
4. All mouldings in plaster work are done by the footsuperficial, as joiners do, by girting over the mouldings witha line.
When rooms have cornices, measure the ceiling or walls,including half the width or height of the cornice respectively,except when the cornices are bracketed, and then onlymeasure up to them. In measuring the length of cornices,take the size of the room, taking one projection in and oneout, and girt the cornices. Enriched friezes, &c., must bemeasured first as plain work, and the enrichments takenseparately afterwards.

Glaziers’ Work.
Glaziers’ work is measured by the foot superficial, and thedimensions are taken in feet, tenths, hundredths, &c. Forthis purpose, their rules are generally divided into decimalparts, and their dimensions squared according to decimals.
Circular, or oval windows, are measured as if they wererectangular ; because in cutting the squares of glass there isa very great waste, and more time is expended than if thewindows had been of a rectangular form.
