BY ELMINA T. WILSON, C. E., Formerly Assistant Professor of Civil Engineering, Iowa State College. WASHINGTON: GOVERNMENT PRINTING OFFICE, 1907. 1039 Ishiu.' more economical of fuel, but more expensive to install than the overhead system. (Ref. 8, p. 821.) BATHROOMS. 11 The minimum size for the bathroom is 6 feet by S feet. An eastern exposure is best and good ventilation should always he secured. If possible the floor should be tiled or of cement with coved base; the walls finished in cement or hard View - plaster. Linoleum, laid before the fixtures are set, makes an economical and sanitary floor covering. The essential fixtures are tub, lavatory, and water-closet. A good enameled iron tub and lavatory will last a lifetime. The enameled ware costs about one-half that of porcelain. The best water-closet to-day is the siphon closet. This should be of porcelain. The fixtures shown in this bathroom would cost about SI 00. PLUMBING. The pipes that cany the water over the house and those that remove it with its accumulated waste are included in the plumbing. The service pipe should enter the cellar well below the frost line. (Ref. 9.) The pressure which forces the water to the points where it is to be used may be procured either by a pneumatic or an elevated tank. If a tank in the attic is 12 used a direct connection from the supply pipe to the kitchen will furnish a fresher supply of water for general use. The hot-water system shown is furnished by a boiler and water-back attachment to the range. (Ref. 10, p. 13.) An additional supply can be secured by installing a hot-water coil in the furnace. The crackling noises in the hot-water boiler and pipes are usually caused by poor circulation due to the sagging of the connection between the water back and boiler, or else to overheating of the water from lack of use. If a hot- water faucet is left open a short time the snapping will stop. PIPES. The service pipe is usually of galvanized iron. Brass or copper pipes are best for the hot-water system; the waste pipes should be of "extra heavy" cast iron or of galvanized wrought iron. The use of lead pipe should be restricted to the short branches of the waste pipes. The soil pipe should run as straight as possible and be continued at least 3 feet above the roof. The main drain in the cellar should be kept above the floor. Each fixture must have a separate connection to the main soil pipe and be provided with a suitable trap. All pipes should be exposed to view wherever possible, as open plumbing is cleaner and more sanitary. (Ref. 11, p. 27.) If a septic tank is used with an inlet pipe bent down below the water line, this forms a trap, and the main trap shown just inside the cellar walls should be omitted. A septic tank similar to the one shown has been built for $23, including labor. (Ref. 10, p. 29.) KITCHENS. PIMP. Id The kitchen should be light, sanitary, and easily ventilated. Tt should be well planned and supplied with up-to-date fur- nishings. It should be compact without being cramped. Too much room is quite as undesirable as too little. (Ref. 12, p. 4.) If a coal range is used, a gasoline or oil stove should be provided for use during the summer, or a combination gas and coal range can be secured. A projecting curved bood of metal over the range or one built of Btudding and plastered on metal lath, with a ventilating thimble close to the ceiling under the hood, will remove the fumes of cooking. The hot-water boiler may be set on a standard or hung in a horizontal position above the range. The sink should be of enameled iron or porcelain supported on enameled iron brackets from the wall. It should have no wooden rim or inclosure. The drain boards should be of white ash, with grooves and a "drip" cut under edges of boards. If a tile or cement floor is not laid in the kitchen, the best substitute is a white-pine floor planed smooth and covered with linoleum before the piping to the sink is connected or the molding of the 14 baseboard set. A perfectly plain trim 5 inches wide with edges rounded off is most suitable for kitchen, storeroom, and pantry. The cupboard shelves should be given three coats of 15 white paint, and a final coat of white enamel. A half-inch space should be left between shelves and wall. Flour, sugar, and meal may be kept in zinc-lined tilting bins, or the counter- shelf can be hinged over a space large enough for the flour barrel to be put in on rollers or a barrel swing. (Ref. 3, p. 31.) It is more convenient to have a storeroom connected to the kitchen than to have a large kitchen. If the refrigerator has an outside door through which the ice chamber is filled in warm weather, in winter this door can be left open to admit the outer air for cold storage. A Berving pantry provides space for the table china and helps keep the dining-room cool and free from odors. The slide between the dining-room sideboard and the pantry saves many steps. The lift, counter- weighted so that a touch will set it in motion, carries fruit and vegetables from the cellar. FURNISHINGS. William Morris said, " Have nothing in your homes that you do not know to be useful or believe to be beautiful." Most of our homes are overfurnished, crowded with useful and us< things. Good furniture should have simple lines and be abso- lutely free from useless ornamentation. Modeled after Colo- 9 nial or Mission style, plain, strong, and tasteful, it will with- Viev> - stand the hardest wear and grow more beautiful with age. Color is one of the important elements in the selection of fur- nishings. A room where colors of rugs, curtains, and walls are inharmonious is not calculated to soothe and rest the weary. An ugly room badly lighted, poorly ventilated, and inadequately heated lowers the level of human life. Where good pictures are not available, use wall decorations, which render pictures unnecessary — e. g., wall papers of good design or some stenciled design upon kalsomined walls. Where pictures are used, let the walls be plain. Do not use pictures and flowered paper upon the same wall. An effective dining room could have a tapestry or colonial landscape paper with plain cream ceiling and white painted woodwork; chairs and table should be plain, of oak or mahogany. A high narrow shelf running around the room for plates or one or two hanging plate racks are sufficient decoration. All curtains, covers to sideboard, serving table, and the like should be washable. For country houses sand-finished walls, either natural or stained with good strong color, flat woodwork of yellow pine, 1 6 cypress, or redwood stained and rubbed, not varnished, hard- wood floor stained to harmonize with trim, combine to give a dignity hard to obtain in any other way. For interior finish that is to be painted, use white pine or poplar, free from knots and pitch. For staining or natural finish, hard pine, redwood, ash, chestnut, oak, cherry or mahogany, ranking in cost in about the order named, are all desirable. The living room of to-day is almost a necessity- in family life. 1 7 With its books, copies of good pictures, fireplace, and com- fortable chairs, it makes the thought of home more attractive and the hall bedroom of a city boarding house less alluring. Bedrooms should have hardwood floors with rugs, kalso- mined or painted walls instead of paper, and brass or iron beds. Hardwood floors should be stained and waxed or treated with shellac and spar varnish. They cost very little more than a floor of soft pine and require only rugs instead of carpet, thus doing away with the most objectionable feature of house cleaning as well as being handsomer and more sanitary. Double floors should be used wherever possible — the under floor of spruce or common fence boards. The upper or finished floor should not be put in place until the plastering is thor- oughly dry and the standing finish mostly in place. North Carolina pine or birch floors are good and cheap, oak is better but more expensive. If only one floor is used, it must be matched to prevent currents of air. (Ref. 8, p. 314.) 11837— No. 8—07 2 10 FIREPLACES. A fireplace will not Furnish sufficient heat for a room in winter weather, hut for spring and autumn a grate fire is all that i- required. It Lb generally conceded that there i.s no better means of ventilating a living room than by B grate fire and no way of making a room more cheerful. (Kef. .;. p. 121.) In recent years brick fireplaces, simply and honestly built, have grown in popularity. Brick can be obtained in beautiful shades varying from delicate cream to deep bronze. The ordi- nary paving brick in connection with stained woodwork gives excellent results. For large living rooms, charming fireplaces 18 may be made of field stone or bowlders with heavy wood shelf and wood or stone brackets. In connection with interiors of a more dainty or elegant character, molded woodwork and tile facing may be used, or a mantle formed on Colonial lines with marble, brick, or tile facing, and woodwork painted white. In place of a mirror use a plaster cast or a good Japanese print set flush in a permanent frame formed of narrow flat strips. The fireplaces should be 3 feet to 3 feet 6 inches wide and 2 feet 6 inches to 3 feet high and 20 to 30 inches deep. Cement makes admirable hearths and will withstand heat quite as well as tile or firebrick. (Ref. 13, p. 219.) A suitable color could be mixed with the cement and the sand should have a good color. A smoking fireplace is a never-ending source of discom- fort. The diagram show r s how the back and throat should be built; the throat forming a long narrow T passage for the flames, not more than 3 or 4 inches wide. Two small steel angles or a cast-iron lintel can be used to support the brick in front with a bar at the back to hold the firebrick in place. INCLOSED PORCH AND BACK DOORS. An inclosed porch is the connecting link between the house and the garden. The plan of the house can be so arranged that this porch makes a convenient summer dining room. The 19 planting of the trees, shrubs, and vines should be such as to give it privacy and a pleasant outlook. There is no reason why a back yard should not be a pleasant place. The part of the yard 20 in daily use should be kept in a sanitary condition at least and, with proper attention, it can be made very attractive. Uncut 2 1 grass, decaying vegetables, weeds, and stagnant water, to breed mosquitoes, are surely unnecessary. 11 RELATION OF HOUSE TO SURROUNDINGS. The architectural treatment of the grounds is inseparably Viev> - connected with the architectural effect of the house. Every place possesses certain advantages as to location, view, expo- sure, the character and situation of the trees, and the like, which calls for a particular means of emphasizing its good points and of evading or concealing its bad points. Many a busy home maker has sighed over some bare and ugly spot around the otherwise satisfactory home and wished for time and means to improve it. Here and there is one who sees what is necessary to be done; the ashes and tin cans are removed, the ground spaded, shrubs, vines, flowers, and grass are assigned to 22 their proper places, walks are built of concrete, brick, or cinders, and the final result is a lawn and garden worthy of the names. The garden should be planned to open off from the part of the house most commonly used so as to be but one of the rooms into which you step out of another. More use should be made of the garden. Apart from the pleasure of gathering and caring for the flowers and vegetables, there is the pleasure of living in the open air. The garden should be inclosed by a hedge or a vine-covered fence and the flowers should succeed each other according to 23 the season. Seats, which should always be simply formed and pro- tected from the weather by a } 7 early coat of paint or varnish, may be conveniently placed for resting where the outlook is 24 most pleasing. A seat of barrel staves will be found extremely comfortable, the curves of the wood adapting themselves well to the body. The paths bordered with flowers or low shrubs should lead straight to the house, ending in an arbor which will serve to 25 screen the kitchen or enlarge the piazza and tie the house to the garden. Pump shelters, back porches, and entrance porticoes may be greatly improved in appearance by the addition of vines. When the house is not supplied with a bathroom and a privy is used, have the walk leading to it sheltered from view and weather and the building itself neat and well placed. If 26 a dry-earth closet is used it may be located very near to the house. (Ref. 10, p. 22.) GENERAL PLAN. It is a common error to give little forethought to the placing of the buildings in their relation to each other, to disregard the l l 2 vuw. outlook from the house, and to take do care in tree planting or 27 to do no planting whatever. A complete and appropriate lay- out .should be the starting point, and time spent in planning an estate will result in economy and beauty when the place is subsequently developed. If poorly planned it means a con- tinued process of tearing down and reconstructing. DAIRY AND POWER HOUSE. The building in which the milk is handled should be entirely separate from the one in which the cows are kept, as great cleanliness is essential in the handling of milk and other dairy products, nothing absorbing impurities more readily. (Ref. 28 14, p. 12.) The building should be well ventilated and so con- structed as not to be readily affected by changes in tempera- ture. The windows should be so arranged that the sunshine may be freely admitted at least once a day. Provision should be made on the ground floor for cooling the milk rapid h' and for the separator and churn, the cellar being used for refriger- ation and storage. The floors and walls should be of tile or composite material, so that a hose may be turned upon them and all thoroughly cleaned. The cellar w^alls may be faced with enameled brick. This power house forms a part of the same building but 29 entirely separated from the dairy. The transmission of power to the various machines of the farm is accomplished by using a dynamo in connection with the gasoline engine, so that motors are located at the various points where pow T er is desired. The house and buildings may be lighted by use of the same plant. (Ref. 13, p. 303.) POULTRY HOUSES. A poultry house should be isolated from other buildings where practicable, built on dry, porous soil, convenient of 30 access, and kept free from vermin. The house should be warm, dry, and well ventilated, having foundation of concrete, brick, or field stone grouted with cement, extending below frost line. A cheap and efficient house can be made of two thicknesses of rough inch lumber put on 2 by 4 studs vertically, with tarred building paper between. The inner layer of boards should first be put in place, the tar paper placed on the outside of these, with well lapped joints held in place by lath and nails, then the outside layer, covering the cracks with ordinary lath for battens. The air space between the boards makes a house warm in winter and cool in summer. The roof should be 13 sheathed with rough boards placed close together, covered View - with tar paper, and shingled. (Ref. 13, p. 192.) A good width for a poultry house is from 10 to 14 feet, length as required. The building should face the south and have plenty of small, low windows, so as to admit sunshine to the floor. A ventilator should be placed on the highest point of the roof, with adjustable openings, so that the temperature of the house may be regulated in winter. Perches should be low, not more than 30 inches from floor, with a smooth, removable platform underneath to facilitate cleaning. Drinking troughs shoidd be in the alley separated from the house by slats. (Ref. 15, pp. 9-18. The posts for runways may be 12 feet on centers. Common rough boards may be used for base, which should be 24 inches high, above which 2-inch mesh poultry netting 36 inches wide should be used, making a 5-foot fence. ICE HOUSE. In building an ice house the main object is to secure isola- tion of the ice by surrounding it with an adequate amount of nonconducting material. The house should have double walls packed with sawdust, a drain at the bottom to carry off water without admitting air, and a ventilator at peak of roof to allow vapors to pass out. There should be no windows, and the door should be as nearly air tight as possible. BARNS. A sanitary and conveniently arranged barn costs but little more than one unsuited to animal life. The conditions gov- erning the planning are very similar to those for a house, i. e., fresh air, sunlight, good drainage, and protection against sud- den changes of temperature. The winter ventilation can be provided for by one or more flues so arranged as to allow the foul air to enter them near the floor line and to pass out through ventilators on the roof, the fresh air coming in near the ceiling. (Ref. 20, p. 29.) Within the last few years a number of very sanitary barns have been built of reinforced concrete. This material is proof against fire, water, and vermin, needs no painting, little repair- ing, and is cool in summer and warm in winter. View 31 31 shows a group of concrete barns on a large stock farm near White Plains, N. Y. The barns have been designed and built to obtain the best possible results with the least expendi- ture of labor in the handling of the stock. The cow stables 14 (the end of one is shown at the right of the picture) have walls, floors, and curved roof of concrete. The walls are hollow, and in them is Installed the "King system of ventilation." Each wing is arranged for forty cows. The Uh^\ troughs arc cast in concrete, with a water inlet at one end and outlet at the other, so thai they may he easily flushed oat. The stalls are made of 1',-inch galvanized pipe and fittings benl to shape and anchored in the concrete. The cows are fastened from each side by chains to a leather collar. The windows swing on their lower v-A^o<, and open into iron cheeks. Tracks hung from the roof on either side behind the stalls are used for the manure carriers which run through the end doors and dump into carts. Modern sanitation requires that the cows he kept apart from the feed and the manure apart from the cows. The concrete roofs are covered with a tar felt, washed over with tar and covered with slag, to make them water-tight. In the floors a layer of felt and tar was placed for a damp course. The feed room and grain storage room are at the junction of the two wings and the hay barn connects with these. The ha}* barn, feed rooms, and silos have concrete walls and shingle roofs. The silos have proved perfectly sat- isfactory. Another example of reinforced concrete construc- 32 tion is the stable built for Dr. N. B. Van Etten, of Xew York City. The walls, floors, and roof are no thicker than required when of wood, but are fireproof, and moisture does not collect on the inside of the walls, although no air space was left. Any part of the stable can be cleaned by turning on water with a hose. Concrete is made of cement, sand, and broken stone, gravel, or washed cinders. (Ref. 16, pp. 1-0.) Wooden forms are 33 constructed, and the cement filled into the spaces required. As 34 the work progresses the lower courses become set and the lum- ber of the forms can be removed and used over again. (Ref. 14, p. 219.) The work must be carried on carefully and intelli- gently, but it is not a difficult form of construction. The suc- cess of the building depends upon the faithfulness and care of the workmen. After the forms have been removed the surface can be given a mortar facing, it can be tooled to remove the outer skin of mortar in which the form marks exist, or it can be washed with an acid preparation to remove the cement and expose the particles of sand and stone, then with an alkaline solution to remove all free acid, finally giving it a thorough cleansing with water. (Ref. 17. pp. G5, 99.) A pebble-dash surface can be secured by using large rounded pebbles in the concrete and when the forms are removed brushing the cement 15 and sand from around the face of the gravel with steel brushes, View - leaving about half of the pebbles exposed. After about twenty-four hours the brushing can be carried on most suc- cessfully. (Ref. 18, p. 643.) In planning the barn, provision should be made for growth of both crops and animals. This can be accomplished either by building for the future or by so arranging the plan that an additional bay can be added with little change in the present building. Greater comfort and better results will be obtained from barns not over 35 feet wide than if built wider. If these are arranged to partly surround a court open to the south they will prove very satisfactory. The barn should be built to store abundance of provender; hence the mow should be without crossties through the middle to obstruct the hay fork, the trusses being placed about 16 feet on centers. It is often found convenient to have a barn for 35 hay with the stock barns grouped around it. The practice of scattering buildings over the farm has been found more incon- venient and expensive than to group them near each other, as all the buildings are more or less dependent. Scattered build- 36 mgs add much to the labor of doing the work. The foundations should extend well below frost line, the basement posts resting directly upon the foundation piers without wood sills at the grade line. The floors of all barns 37 and sheds should be dry and well drained. The best and most economical floor for a dairy barn is of concrete. The ground floor should be raised enough to give a good fall in all directions from the barn. In the construction of stables for live stock, 38 especially milch cows, the ventilation must be proportioned to the number of animals; 500 cubic feet of air space per head is the least amount allowed in good designing. The stalls should have a slope toward the gutter of about 2 inches in 5 feet. The fall of the gutter should be about 1 inch in 20 feet. An example of good planning is shown in " Three Rivers 39 Farm," the home of Mr. E. W. Rollins, near Dover, N. H. An arbor extends from house to barn and the garden lies at one side of this arbor. The native trees have been used to give shade and shelter, but are not allowed to cut off the beautiful outlook over the hills and river. The barns form three sides of a court, a convenient and labor-saving arrangement. The location is exceptional, but the neatness of the yards and buildings need not be so. The Iowa farm shown in the next view was started a hun- 40 dred years or so later than the preceding, and the details have not been so well looked after. The buildings have been 16 dropped down on the yard with little thought for convenience. The tree planting is excellent, hut no one has taken the time to plant the vines and shrubs needed to soften the outlines and to separate the hams from the house. HOG HOUSES. -1 I Houses built for the keeping or breeding of swine should he easily cleaned, well lighted, and well ventilated, with separate feeding floors and sleeping quarters. The feeding floor, located in full sunlight, should he of concrete, 12 feet wide and as long as required, slightly sloping, about ' inch in 12 inches, to a gutter on one side. The feeding trough may be formed of concrete. and should extend along one side and he protected by a swing- ing fence from the hogs while being cleaned or filled. For the sleeping quarters, the "Ring system of ventilation"' is excel- 42 lent. (Kef. 20, p. 29.) The pens, walls, and floor may be of concrete, with iron doors, so that all may he kept clean. The runs may be separated" by wire fences and should have a shal- low concrete basin at one end, where the hogs may lie in water in the hot weather. FENCES. A irood fence carefully built will add much to the appearance of a farm. Wooden fence posts are becoming more expeii and cement or iron posts are often substituted. The cement posts may be made on the farm if sand and gravel can he easily 43 obtained. (Ref. 13, p. 213.) The casting of ornamental shapes in concrete may be accomplished by the use of sand, wood or plaster of Paris molds. The concrete fence at the Gedney Farm had the posts cast in position, with grooves on e;ich side, into which the rails were dropped and the grooves 44 filled with concrete. The rails, 4 by 9 inches and about 16 feet long, were cast in separate forms and put in place after the concrete had thoroughly set. They have a '.-inch reinfon rod in each corner with 1-inch stirrups every 2 feet of length. REMODELED HOUSES. The farm shown in this view had been "running down" for a generation before taken by the present occupants. There were no trees near the house, but brambles and weeds grew 45 everywhere. The untidy outbuildings were located on a steep hillside covered with stones and bushes. The rickety feE and general air o( untidiness are typical of a certain class of farms. 17 The first improvement made was to clear out the weeds and View - thickets, fill the hollows, rebuild the stone walls, add a layer of good soil, and seed. It was then possible to go all about the buildings. The apple trees being pruned and cared for, took on new beauties. Lombardy poplars were planted because they are fast-growing trees. The elms and maples were trans- planted while still small trees, and after five years made quite a 46 showing. The flower beds are massed near the house; the plants against the old brick walls seem to make the house less obtrusive and more a part of the landscape. The new shed and terrace, although not exactly in keeping with the old house, are well built, the terrace making an excellent outdoor living room when covered with vines. (Ref. 19, p. 13.) This house was not chosen because of its architectural excel- lence, but to show that no matter how unpromising a house may be it is possible to convert it into a comfortable home. The well-kept drive and lawn give the place a prosperous look, 47 while the two-storied porch means solid comfort in summer 48 weather when inclosed with screens and utilized as dining and sleeping rooms. The arrangement of the vines in front of the house is very unfortunate, shutting off the view from the win- dows, as they apparently do. Grown upon a trellis against the corner of the house or with the rocks as a background they would be excellent. To improve the existing conditions upon a farm, development of additional resources are often unnecessary; much may be accomplished by a different disposition of materials already at hand. APPENDIX.
