A DESCRIPTION OF THE DESIGNS IN PAIN's BRITISH PALLADIO. 
Plate I.
The principal plan and elevations of a gentleman's house, with the principal
timbers for the floors, roofs, partitions, and the scantlings figured for
practice, in proportion to their bearings.
The length of the griders on this floor is 23 feet; the clear between the
walls 21 feet 6 inches; the scantlings 13 by 12 inches; the clear bearing
of the binding-joist about 10 feet, the scantling 9 inches by 4 1/2, and
they must be framed about half an inch below the underside of the grider,
and the grider furred down for the lathing, otherwise the ceiling will crack
at the grider, which will spoil its beauty. The scantling of the bridging-joist,
5 inches by 3, to lie about a foot apart; the ceiling joist, 3 by 2 1/2;
the distances for framing the binding joist from 4 feet to 6, or 6 feet 6
inches, as they will best come in. The distance for framing the trimmer from
the chimney-breast 1 foot 6 inches, or not to exceed 1 foot 9 inches. Wall-hold,
for griders to lie on the wall, from 9 inches to 12 inches; ditto for binding-joist
6 inches. It is necessary to turn arches over the ends of griders; for, if
any settlement should happen, that will prevent the wall from breaking.
Of the rooms on the principal plan. 
A the dining-room; B the withdrawing-room; C the common sitting-parlor; D
the breakfast-room; E the best stair-case; F the back-stairs; G vestibule.
Fig. H the section of the floor for the principal rooms; a the grider; b
the binding-joist; c the bridging-joist; d the ceiling-joist. This section
is drawn half an inch to a foot. Divide the depth of the binding-joist into
eight parts, and dispose of them as figured to the tenons and bearings.

A the kitchen; B servants hall; C the housekeeper's room; D store room to

K stair-case to the area; L section from M to N on the plan.
PLATE III.
Plan of the one-pair of stairs floor, and attics.
A the one-pair floor; B the attic floor. The one-pair is divided into five
bed-rooms, the attic into six. Fig. A is the section of the floors for the
one-pair and attics, drawn half an inch to a foot. The principal joists to
this floor are about half an inch deeper than the griders, to prevent the
ceiling from cracking; and they are framed at such a distance as will admit
of two or three immediate joists between them, as shewn in the section. The
ceiling-joist is framed into the principal joist, as in the section. B the
intermediate joist; D the principal joist; C the ceiling joist; G the griders.

The plan of the roof, and section of the floors.
Fig. A the plan of the roof; B the beams; C the binding-joist for the ceiling-floor;
D the ceiling-joist; E the raising-plate; F the principal rafters. The length
of the beams is 48 feet, which have a bearing on the party-wall, so that
the clear bearing does not exceed 24 feet; the scantling of ditto 9 inches
by 6 1/2; length of the principal rafters 15 feet; scantling, 9 inches at
bottom, 7 at top, 6 1/2 inches thick; king-post 1 foot 4 inches by 6 1/2
thick; struts 6 1/2 by 4; raising plate, 9 inches by 6, binding-joist, 6
by 4; ceiling joist, 3 1/2 by 2 1/2; scantling to quarter-partitions, 4 by
3; door-post, 4 by 4. Fig. B, scarfing-plates and dove-tailing at angles;
