In the all-important question of kitchen and servants" quarters be modern from start to finish. The old farmhouse kitchen was both living room and workroom. It was large and cheerful. Accordingly the reconstructed house continues it as a living room. The new kitchen can best be located in an extension either original or new but designed to be in keeping. Here the noises and odors of cooking will not permeate the main structure and with mouse-proof new part.i.tions, kitchen, pantry, and servants" quarters can be arranged so they will be logical and convenient. Wherever possible the garage ought to be a part of the service wing for ease of access and heating in winter.
Because of the individuality of old houses, returning doors and windows to the original location is not entirely mandatory. One here and there can be moved a little without destroying resemblance to the original. With the plans for re-erection complete, everything is ready for a second raising of the frame. New sills cut to the same dimensions as the old are put in place. Then corner posts, summer and plate beams, and other princ.i.p.al timbers are hoisted to their proper places. By virtue of numbering and marking with colors--red for the ground floor, blue for the second, and black for the attic is one reconstructor"s code--each mortice and tenon joint is put back just as it was originally and the whole frame made plumb. Now hardwood pins driven home at its joints make the skeleton firm and solid. Then comes the new roof of whatever type of shingles selected. Along with it starts the work of enclosing the side walls. These steps, of course, apply to a structure taken apart piecemeal. With a "flaked" house, roofs and walls are returned to position as panels. Making saw-cut cracks tight is the only remaining step.
If possible, the old studding and weather boarding are used, although, as neither will show, new material can be subst.i.tuted if desired.
Similarly a rough flooring of cheap lumber is laid as a foundation for the old. Such features as the main stairway and paneling, cleaned and repaired, are now brought in through large openings in the side walls and put in place before enclosing the frame is completed.
There are two points of view about using old window frames. One favors using them despite lack of mechanical means for raising or lowering the sash. The other, reasoning that many of the frames are bound to be badly weathered and not too sound, recommends new ones complete with weights and cords. With the latter, the old effect is preserved by reproducing the exterior molding exactly and by using the original interior trim.
After enclosing is completed and the interior part.i.tions are in place, the house is ready for lath and plaster. Wood or metal lath or any one of the various plaster boards can be used as foundation. Now comes a fine point. Present-day plasterers produce a much finer finish than was the rule a century ago, but if they understand the effect desired they will restrain themselves and possibly omit the final skim coat.
The next details are the window sash, interior trim, and the final exterior siding. The latter can be either the original clapboards, new ones of the same width, or the long riven shingles. Whatever is used, for protection against winter winds, the boarding ought to be sheathed either with building paper or a quilting. Likewise, the tops of all door and window frames must be properly flashed. This prevents rain leaks which are bound to stain the plaster.
Before the original flooring is re-laid it should be thoroughly scrubbed with a mild lye solution to rid it of old paint, stains, and dirt; as many of the old nails removed as possible, and injured sections discarded. Since there is bound to be an appreciable loss, the attic flooring can be used to take the place of that discarded or an additional amount bought from some wrecker specializing in materials salvaged from old structures. Along with cleaning the old flooring, it is frequently wise to have the edges re-planed so they will be straight and true. It obviates wide cracks that gather dust and lint.
In taking the old house apart, a bit of siding may give a clue to the original color outside. Under the various coats of paint and paper of the interior the owner may get glimpses of the scheme of decoration used when the house was young. We may not realize it but Colonial Americans were partial to color in the home and used a number of very effective off-shades now largely forgotten. If these can be discovered and samples preserved for matching, the results will be authentic and at the same time give the house an individuality and atmosphere that will not be met with elsewhere.
[Ill.u.s.tration: AS THEY BUILT A CHIMNEY IN THE EIGHTEENTH CENTURY

A house that can be purchased for removal will not often be completely equipped with its original wrought-iron hinges, door latches and locks. But the chances are that enough will remain to indicate what they were and replacements that match and fit can be bought from an antique dealer specializing in old hardware.
Since electricity is entirely a modern convenience, selecting fixtures must depend entirely on the owner"s taste. One of the most satisfactory restored houses we have seen has very few fixtures and many portable lamps chiefly made from old jugs and converted astral oil lamps. In bathrooms, kitchen, cellar and garage, no attempt was made to affect the antique. Being strictly utilitarian rooms, simple fixtures that would provide the maximum of light were employed.
So "if only" has become an actuality. The old house is now comfortably settled on its new site and like most transplanted things will thrive better if some faint flavor of its old surroundings is present, such as an apple orchard or one or two fine old trees that look as if they and the house had grown old together.
THE SMOKE GOES UP THE CHIMNEY
[Ill.u.s.tration]
_CHAPTER VIII_
THE SMOKE GOES UP THE CHIMNEY
"Remember that the new chimneys are not to smoke," wrote General Washington from New York in 1776 to his kinsman and overseer, Lund Washington, regarding the remodeling of Mount Vernon. That admonition is just as necessary today as then. A chimney is still an essential part of a house. Also, despite the newest and most effective heating systems, family life, in the country at least, still centers around the hearth. Old, new, or merely middle-aged, no country home is considered properly equipped without at least one fireplace.
There is no use in pretending that they are needed for heat, but the leaping flames and brisk crackling of burning twigs are a cheery sight and sound. "Harriet _will_ have her fireplace fire even though she has to open all the doors and windows," chuckled one householder. This ceases to be a pleasantry if doors and windows have to be thrown wide to let out smoke instead of excess heat. Then this center of family cheer becomes as exasperating as any other inanimate thing that doesn"t work.
If, by purchase of an existing structure, a householder has become heir to such a problem, simple things, like fireplace hoods, capping the chimney, or increasing its height, can be tried. If these fail, architectural counsel is the next step. Such trouble is more frequent in houses dating after the stove era than before. The old masons built fireplaces for practical use rather than for occasional indulgence.
They had never heard of aerodynamics but they knew how to construct fireplaces that would give out real heat as well as chimneys that carried the smoke where it belonged, up and out.
Of course some unwise features are to be found in the old work but, for the most part, design and proportions cannot be improved. The angles of sides and back, size of opening and throat, location of smoke shelf, size and proportions of smoke chamber, all were determined through years of rule of thumb experiment where only the best results survived. Therefore, the owner of an antique country home with chimney and fireplaces intact should think twice before he gives orders to demolish them. Similarly, he who is building a new house can well plan to reproduce the old fireplaces in size and shape.
Building proper chimneys and hearths was slowly evolved through the centuries. In the late 18th century, an American codified this masonic lore and established the scientific basis for a proper fireplace so cogently that even today his principles form the backbone of fireplace building. He was born Benjamin Thompson, March 26, 1753, at Woburn, Ma.s.sachusetts, but is better known as Count von Rumford of the Holy Roman Empire.
"The plague of a smoking fireplace is proverbial," began Rumford in his treatise on the subject, written during his years in the service of the Elector of Bavaria. Stripped of the involved terminology characteristic of the natural philosopher of that day, his specifications for a smokeless, heat-radiating fireplace are very simple and depend on three fundamentals. First, the size of flue must be in proportion to the fireplace opening. Second, the angles of back and jambs must be such that they will reflect heat into the room.
Third, throat and smoke chamber of proper size and shape are essential because the former improves the draft while the latter prevents smoke from being blown out into the room by a down draft within the chimney flue.
From this it is clear that the New England-reared count of the Holy Roman Empire was really describing the type and design of fireplace in general use at home in his boyhood and explaining the scientific reasons for its superiority over European rectangular ones, built throatless and without a smoke chamber. As stated before, technical men today generally go back to Rumford"s work and the American tradition behind it, but in one particular they make a wise departure.
Instead of a single common flue, they advocate separate ones for each fireplace.
These modern specifications, based on several centuries of good practice, are as follows: The fireplace should be at least 18 inches deep and have a hearth 20 inches wide. The size of opening must of course be in proportion to the dimensions of the room, but one with lintel less that 26 inches above the hearth is not practical because of difficulty in tending the fire. A good maximum height is 42 inches.
The width should be in accord and exceed it so that the opening is a well-proportioned rectangle with its greater dimension horizontal.
In our country home, built about 1765, there are three fireplaces, each of different size and proportions. The largest, where the cooking was done, is 50 inches wide by 37 inches high and 18 inches deep. The one in the old parlor has a width of 38-1/2 inches, a height of 28-1/2 inches, and a depth of 13-1/2 inches. The smallest has an opening just off the square which is 27 inches wide by 25-1/2 inches high with a depth of only 11 inches. All three are non-smokers under all conditions of wind and weather. With proper size of wood they are easy to tend and good sources of warmth except in real winter weather. Each is individualistic in hearth dimensions, the largest of course being that of the old kitchen with a hearthstone over seven feet long by two feet wide.
Whether heat radiates into the room, or goes up the chimney along with the smoke, depends on the angles of fireplace sides and back. The former should be set at an angle of about 60 degrees so that they flare outward from the back wall. There are two schools of thought regarding the back. One would have the forward pitch begin one third of the distance from floor to lintel; the other favors the slope starting at the bottom and continuing upward in an unbroken plane. In the former, the pitch should be about 23 degrees from the vertical; with the latter, 18 degrees will suffice.
From this point the consideration of dimensions goes up the chimney.
In its standard ordinance for chimney construction, the National Board of Fire Underwriters calls for fireplace flues with a draft area of one-twelfth of that of the fireplace opening and determines this area as a circle or ellipse that will fit within the tile used to line the flue. As it is difficult to obtain flue linings of exactly the desired area, it is better to select a size slightly larger, rather than one smaller, and so make sure of sufficient capacity under all weather conditions.
Between the lintel of the fireplace and the point where the flue commences come the three structural features so stressed by Count Rumford. They are the throat, smoke shelf, and smoke chamber. As its name implies, the throat is the opening through which smoke, hot gases, and some flames pa.s.s on their way upward. Experts hold that its correct construction contributes more to the efficiency of a fireplace than any other feature, save proper flue design. The area of the throat opening should not be less than that of the flue and its length must be equal to the width of the fireplace. It should be located eight inches above the lintel. Under present practice, a cast-iron throat with a damper which can be opened and closed to regulate the up-chimney flow is standard. Also, when the fireplace is not in use, this damper can be closed and so prevent loss of other heat.
The smoke shelf comes immediately above the throat and is formed by recessing the brickwork of the back the full width of the chimney for at least four inches. With very large fireplaces, it may be as much as twelve inches. The object of this feature is to stop any accidental draft within the flue from going farther and blowing smoke out into the room. The area in between this and the flue itself is called the smoke chamber. Here the walls are drawn in with a gradual upward taper to the point where the flue lining begins. The chamber so formed can and does hold acc.u.mulated smoke temporarily when a gust of wind across the chimney top cuts off the draft for a moment.
In building chimneys, the old masons varied their structural ways and materials according to the part of the country in which they worked.
New England workmen were partial to a central chimney, the core around which the house was built, and their usual material was stone.
Occasionally brick was used but this material was more in favor with old houses of the middle states and the South. Here, instead of the central stack, a chimney was built in each of the two end walls. The climate was milder and the style of architecture, with central hall and stairway, made such practice desirable.
The mark of an old chimney is its ma.s.sive construction. In those of the central type, it is not uncommon to find a foundation pier of ten by twelve feet in the cellar. This was laid dry and just below the level of the first floor, large transverse beams were put in place to support the hearthstones of the fireplaces above. Here dry work stopped and, from there to the chimney top, all stones were laid in a mortar made of lime and sand. At a point above the smoke chambers of the various fireplaces and the brick-oven flue (always a part of the kitchen fireplace) all came together in a common flue. Here the chimney gradually tapered to the top and was usually about three or four feet square where it came through the roof. Originally such chimneys were entirely of stone. Comparatively few are found in original condition today. Time and weather usually made repair or repointing of the portion above the roof line necessary and, in the course of it, brick was often used instead of stone.
By ample proportions the old masons achieved fire safety. This can now be accomplished with a distinct saving in s.p.a.ce if one is building a new chimney. There are certain fundamental provisions as stated in the standard chimney ordinance cited above. These are tedious and complicated reading for the layman, but to architects, builders and masons, they simply mean standard workmanship and materials that have been used for years to insure correctly functioning chimneys. Possibly a brief resume of these fundamentals is not out of place in order that the prospective country house owner may not demand the impossible in his schemes for convenient closets, cupboards, or even a stairway.
The chimney may be built of brick, stone, reinforced concrete, concrete blocks, or hollow tile of clay or concrete.
All chimneys should rest on an adequate foundation located below the frost line and both chimney and flues should adhere strictly to the perpendicular.
If an angle is necessary, it ought not to be greater than 45 degrees.
No offset should be over three-eighths of the total width of the chimney.
In laying brick or other material, care should be taken that all joints are tight and completely filled with mortar.
Unlined chimneys are not prohibited but the best arrangement is one in which all flues are lined with fire clay tile, joints well set in mortar, and each flue separated by a part.i.tion of brick. Only sound, uncracked tile should be put in place.
Fireplace walls must be of ample proportions to support the chimney and at least eight inches thick. It is further suggested that they be lined with fire brick.
The woodwork around fireplaces must not be closer than four inches to the back wall of a chimney and floor beams must be two inches away from a chimney wall. The s.p.a.ce between should be filled with loose crushed cinders or other porous incombustible material to form a fire stop.
Plaster for exterior walls of a chimney should be applied direct or on metal lath. No wood furring or lath.
