with Carpentry, which is principally a house building art, and is quite a different thing when applied to ship-building and other purposes. Other sciences called upon in building the house are those of Roofing and Slating, of Cornice-Making, Plastering, of Stair building, of Sash, blind, and door making, of parquetting, of chimney building, of mantel making. The subject of Builder's Hardware is also one to the study of which men devote their lives, and in which it is necessary to have the purposes of the house constantly in view. This is therefore a science directly ministrant to the house-instinct. Another such science is Plumbing. Simple bell-hanging (if it is not obsolete) is practised by the locksmith. But the makin gof Annunciators of various kinds is a somewhat serious study. So is that of making Elevators and mail-shutes. The furniture of the house may be divided into Movable Furniture and House Decoration. The common modes of decoration are by painting and Paperhanging. But painting is not peculiar to houses, though it is a somewhat peculiar art as applied to houses.
