Linings up to 9 inches in width are better measured per foot run. Over that measure per foot super., and state that they are cross-tongued, and fully describe the labours on them. Include backings in the description. State if backings are framed. Keep splayed linings separate, and so describe them. Fully describe panelled linings, and state the number of panels in the set.

## Architraves

Measure per foot run. Take the extreme length on the outside edge, and include the mitres and grounds. If the architraves are on wrot framed grounds, measure the grounds separately per foot run, the extreme length on the outside edge.

## Note

In measuring linings, grounds, architraves, etc., the only dimensions actually measured will be the nett brick opening, for which refer to previous sheets; and in practice it is usual to supply the same dimension for the length of the linings, making no allowance for backings. The length of wrot grounds will then be the same dimension plus four times the distance between back of lining and outside edge of grounds for passings at angles. The dimension for the architrave will be that for the grounds plus four times the projection of the outer edge of architrave beyond the outer edge of grounds. Take, for example, a window opening, the dimension for deduction of internal reveal being 3 feet 9 inches by 7 feet 3 inches, finished with 1-inch rebated linings, and 3/4 x 4-inch wrot framed and beaded grounds, and 1 x 2 1/2-inch moulded architrave, as Fig. 29.

 18.3 2/ 7.3 = 14.6 3.9 18.3 1" x 3 1/2" wrought rebated linings and backings. 18.9 18.3 4/ 3" = 1.0 19.3 3/4" x 4" wrought, framed, splayed, and beaded grounds. 19.7 19.3 4/ 1" = 4 19.7 1" x 2 1/2" moulded architrave and mitre.

## Window Nosing

Measure per foot run, and describe as "tongued and rounded," or as the case may be. If with small moulding tongued on under, this may be included.

Number the notched and returned ends, mitres, fitted ends, etc.

## Window Board And Bearers Up To 9 Inches Wide

These are best measured per foot run as described for Window Nosings. Over 9 inches wide, measure per foot super., and describe as cross-tongued; and any moulding under should be separately measured, and describe as rebated and grooved to under side of window board. Number the notched and returned ends, mitres, fitted ends, etc., of window boards, and separately number returned ends, fitted ends, and mitres to moulding under; in the latter case these numbered items are "written short" in the Bill.

Note that any item described as "rebated and grooved," or "tongued and grooved," includes both the rebate, or tongue, and the groove; but if only described as "rebated," or "tongued," the groove must be separately measured, unless it has been included in the description of the item in which it occurs; as, for example, when window frames are described as "grooved " all round for furnishings. When groove is measured separately, if it cannot be run right through, describe it as " stopped."

Arch Boards over square frames in segmental headed openings are measured per foot run, and thickness and extreme dimensions given. State that they are tightly scribed to soffit of arch. Sometimes an extra deep head is specified to the frame for the same purpose, to run up behind the arch when the frames are within reveals. Measure this per foot run as extra on sashes and frames for head being so many inches deep.

Casements are measured per foot super., and described. State how many in the superficial quantity. If in small squares, state it, and if hung or fixed.

Glass, as before described.

Number.

## Frame

Measure per foot run, and describe. Allow in the length for framings and horns (if any).

## Mullions

As last. Describe as "framed."

## Transome

As last. Describe as "framed."

## Sill

As last. Describe as "framed."

Any special labour to frame or casement which cannot conveniently be included in the description is measured per foot run; as, for example, any special labour to meeting stiles or bottom rails of casements.
