OF THE ELEMENTS OF
reaching to the top of the building ; and in them were vents,
made in all those places where they wished to procure heat,
covered with lids, which were slopped or unstopped at plea-
sure. Our own habitations would be rendered (in my opini-
on) much more convenient if we adopted this plan.
Chimneys at present are made, for the mold part, in the
thickness of the walls, v/ith their openings visible in the apart-
ment, and their funnel rising outwards above the top of the
roof. The apertures are limited by two jaumbs, and the
mantle-tree, on which a pyramid is construded, reaching to
the ceiling, and on it a shelving funnel is ereded, The ssoor
of the chimney is called the hearth; the part opposite to the
opening is called the chimney’s back.
Muet proposes these following proportions for chimneys :
in kitchens, saloons, and dining rooms of an extraordinary size,
the breadth of the apertures should be from 6 to 8 feet.
Their height from 4 i to 5. The projection or depth srom
the forepart of the jaumb measured to the back os the chim-
ney from 2 \ to 3 seet. Thence the hollow of the pyramid
gradually diminishes till it reaches the bottom of the funnel 4
or 5 feet long; from 10 to 15 inches broad, and not more.
In bed chambers the breadth os the opening should be from
5 t to 7 feet; the height 4 feet or 4 \ ; the projection 2 feet
or 2 In common parlours and servants rooms, the breadth
of the opening should be from 4 to 5 feet; the height and
projection the same as in bedchambers.
Palladio proposes, in a summary way, that the funnel in the
chimnies of rooms should be srom six to nine inches wide,
and two feet and a hals long, and that the opening of the fun-
nel where it joins to the Pyramid may be somewhat con-
traded. The mantle-tree should be of very elegant work-
mansnip, and by no means os the rustic kind, unless in very
