The Attic story can very readily be Third Floor. divided into four good-sized rooms, which would afford ample accommoda- tion for domestics. The Basement Kitchen is located be- neath the Dining-Room E, having exactly the same dimensions, and a Pantry corresponding with the one in the Dining-Room marked as G. A large Range will be required, with Water-Back, &c, and a Circulating- Boiler, holding 60 gallons, of galvanized iron, with all the fixtures and connec- tions; Water-Back, &c. It will be necessary to have two fur- naces, in order thoroughly to warm a building of the dimensions of those we are describing, and to distribute the heat, properly and uniformly, through- out all the apartments. The greatest care should be exercised, in the con- struction of the Flues, both for the Hot- Air and for Smoke. They should be perfectly uniform in size, and of a very smooth surface. In order to secure these* essential points, tin is frequently used as the material for lining the flues, and it is usually built in the wall, during the construction. This is a practice, however, which we disapprove of, as the brick is, in almost every case, laid around the tin, without any regard to system, or regularit}^ ; the result of which is, that, in the course of time, the tin corrodes, leaving the flue in such a rough and irregular state, that the fric- tion of the current will not permit any draught, thus leaving it equivalent to no flue at all. There is another method, which has met with much favor, and is now quite extensively practised, viz., that of using Terra Cotta Pipes, of an oblong shape with round edges. These vary in size ; and, being glazed on the inside, form not only a durable, but safe and efficient material for the purpose. They are generally set in flush with the wall ; and plastered over, as is done on the surface of the wall. These flues are manufac- tured, expressly for the purpose, in lengths of twenty-four inches, with con- nections, register and pipe openings. Still another mode has been success- fully tried, that of building the flues open on the face, from the bottom to the top, and uniform in size throughout. They are afterwards regularly plastered with plasterer's mortar, coated to a smooth surface, and white-coated. They are then covered on the face, with a course of slate, the smooth side inwards, secured to the wall with plaster, and, occasionally, by a nail, driven into the joints of the brickwork. This course of slate is theu coated over with the same mortar, and a second layer of slate is bedded firmly in this mortar, the surface of which is then ready for the regular plastering coat. With reference to these different modes of constructing flues, our decided
