“ There seems to be a general consciousness of the fact that, in the struggle for wealth and the greed for wide possessions, as well as [Pg 8] in the inherent difficulties of our situation—thrown as we have been upon a new and vast continent—we have too long neglected the culture of the Vine, one of the most ancient and useful arts of life; an art which has, in all ages, been the fruitful source of comfort and luxury, of health and happiness, to the masses of mankind. ”

“ The principal advantage of the Polyprosopic roof, is its portability, that is, it can be made in sashes, and transported to any portion of the country, thus obviating the necessity of painting and glazing in the hot atmosphere of the interior, or loss of time from storms, etc., on outside work. The fixed roof house can be sent anywhere primed, but the glazing and second coat of paint must be done after the erection of the building; either house we think equally well adapted to growing purposes, but as a matter of beauty and economy we give the preference to the fixed curvilinear roof. ”

“ One of these which may be noticed is a neat fountain in the centre; always a pretty feature wherever it can be introduced. Another is a rustic niche or alcove in the north wall, built of rough stones, over and through which the water constantly trickles into a basin. Its full beauty will not be seen till it has acquired age, and become covered with mosses and ferns. Fortunately for the plants and for good taste, there is no shelving in this house. Beds are formed of brick, with a neat coping, in which the pots are set. ”

“ Mistakes are frequently made in the erection of structures for the growth of plants which, notwithstanding all the skill and art of experienced gardeners, render it impossible to arrive at satisfactory results. One of the most common of these is the excessive height of the roof. Men of experience in the construction and use of glass houses, have satisfied themselves that the lowest elevation which the uses and purposes of the building will admit, is the best. The difference in temperature between the floor and roof of a house twenty feet in height, will vary from ten to fifteen degrees. ”

“ There is still much to be learned in the matter of [Pg 16] exotic grape-growing in this country, and, in fact, in the management of conservatories, orchard-houses, and all descriptions of horticultural buildings, and all classes of plants cultivated under glass. Whatever progress may have been made abroad, where experiments are carried on upon a large and costly scale, and often with eminent success, is of little or no value to the American horticulturist. Our climate is very different in its character and conditions from that of Europe, and especially that of humid England. ”

“ All gardeners know the difficulty of rooting cuttings as warm weather comes on. When the thermometer marks 80° in the shade fires are laid aside; and if the rooting of cuttings is attempted, the sand or soil in which they are planted will be 10 or 15 degrees lower than the atmosphere, or the opposite of the condition required for success.
The advantage possessed by the gutter or tank, as a means of bottom heat, over smoke flues or pipes, is in its giving a uniform moisture, cuttings scarcely ever requiring water after being first put in, and then only to settle the sand about them. ”

“ The American people are rather disposed to be self-reliant, and we may, therefore, safely predict that, when we take hold, in real earnest, of the business of grape culture, either under glass or in the open air, we shall do it with our customary determination and energy, and that success will just as surely follow as it has in other cases where imported ideas have been improved upon and superseded. ”

“ It occasionally happens that a conservatory attached to a dwelling is heated by the same steam apparatus employed to heat the latter, but we believe that a person who should advocate, at the present day, the general adoption of steam as a means of heating horticultural structures, would be regarded as belonging to a generation which has now passed away.
Steam travels through pipes with great rapidity, and parting with its heat rapidly, it becomes quickly condensed, unless the boiler is of large capacity and capable of furnishing a full supply. ”

“ If the situation is a dry one, and the soil gravelly or sandy, then a pit may be excavated, of the size of the intended frame, and three feet in depth. A hollow brick wall should be built up from the bottom, six inches above the surface, if it is intended that the bed should be permanent; otherwise the excavation may be lined with boards, or if designed for only a season's use, it may be left without any support. Hot-beds made under ground require less material, are more lasting in their heat, and require less attention than those built on the surface. ”

“ THE COLD PIT.
Many who have not the advantage of a green-house, wish to preserve over the winter their half-hardy plants which have ornamented their garden during the summer. These are generally consigned to the cellar to dry up and be forgotten. In the darkness they loose their leaves, and when in spring they are again brought to light many are dried up and dead. Properly constructed cold pits offer superior advantages for the protection of many plants of a half-hardy nature, and indeed some that are usually considered tender here find a congenial location. ”

“ It cannot be questioned that houses of moderate extent can be heated at much less expense for the original cost of apparatus by the flue system than by any other now before the public. Flues have the advantage over steam or hot water in their power to generate heat and supply it to the green or hot house [Pg 23] in a very short space of time, and with this apparatus, the fires may be allowed to go out on mild and bright days in winter, with the certainty that heat can be easily and quickly commanded at nightfall. ”

“ The enjoyment of a country place naturally depends very much on its neat and tasteful appearance, the completeness of all its appointments, the order and good taste of all its arrangements. And although we do not advocate extravagance, or needless cost in ornamentation, which would be unsuitable to the purpose for which these structures are designed, we think that true economy would indicate the use of the best materials and workmanship requisite for substantial and permanent buildings. Horticultural buildings are not intended for a few years' use merely. ”

“ Soil or sand, to the depth of six to ten inches, is usually placed upon the tanks, and used as a plunging bed for pots containing cuttings; or the cuttings are sometimes inserted in the bed itself.
Any arrangement by which vapor from the tanks is admitted to the roots of plants is to be avoided, for however desirable a moist bottom heat may be, it is found from experience that the soil is frequently rendered a mass of puddle, in which no living roots can exist.
A portion of the covering of the tank may be made moveable to allow moisture to escape into the house when required. ”

“ The boiler is so set that the back of it and all the connecting pipes are inside of the house, only the fire and ash pit doors project through the brick partition into the boiler pit. Much heat is generally wasted from hot water boilers by the direct connection of the chimney with the outer air, that might be saved by means of a well constructed flue. It will be seen that the smoke from the boiler is carried under the tank, in this instance through 8 inch vitrified drain pipe. To prevent the cracking of the pipe near the boiler the first 6 or 8 feet is laid with cast iron pipe. ”

“ Well managed Orchard houses will give us, without doubt or failure, the Peach, the Apricot, the Nectarine, the Plum, the Fig, and many other fruits in great perfection. With the addition of fire heat these [Pg 132] may be forced, and the fruit obtained much in advance of its natural season.
In England, houses for the growth of these fruits, which will generally not ripen in the open air of that climate, have been in successful use for a number of years. In these houses the trees are planted in prepared borders, which gives the roots liberty to ramble at will. ”

“ The boiler pit is sunk beneath the floor of this room, and has connected with it a coal bin and shoot. Communicating with the potting-room is a propagating room, in the north end of the conservatory, and divided from it by a solid partition. It is provided with hot-water pipes for furnishing bottom heat. It will propagate all the bedding and other plants needed on the place. It will thus be seen that there are ample facilities for furnishing an abundant supply of grapes and flowers. The house, as a whole, forms a marked feature of the grounds. ”

“ The sides, except the potting room, are of glass, the sashes being about three feet high. Every other sash is hung at the bottom, for the purpose of ventilation. The roof is a continuous glazed roof, and is quite flat, which is a decided advantage to the plants within. There are no ventilators in the roof, the top ventilation being effected by means of the sashes over the doors at each end, which are hung at the bottom for this purpose, and afford abundant ventilation for a house the length of this one. ”

“ General collections of plants cannot well be grown in one house; for this reason, we have the house divided by a glass partition. By an arrangement of valves in the hot water pipes, and independent ventilation, a different temperature can be maintained in each. Plants requiring a considerable degree of heat will find a congenial location [Pg 130] in the central house, while those in bloom, and others to which a cooler atmosphere is more suitable, will be placed at the circular end of the building. ”

“ By the use of glass houses on city lots, much enjoyment may be had by all who have a desire to spend their time in growing fine fruits and flowers. Pot vines and trees condense a vineyard and orchard into a wonderfully small space, and border vines yield a harvest of glorious fruit that surprise all not accus [Pg 97] tomed to seeing and eating such luxuries. Our city lots, with rare exceptions, are well adapted to the growth, under glass, of grapes and orchard fruit, and the forcing of vegetables. ”

“ But if tanks are constructed of substantial and enduring materials, they possess little if any advantage, on the score of expense, over hot water pipes, while they occupy much more room and are unsightly objects in a well ordered green-house.
Wooden tanks are frequently used where the heat is required to rise perpendicularly from them. If constructed of good pine plank, well put together with white lead, and thoroughly painted inside and out, they will last for several years. Scarcely any heat will be radiated from the sides and bottom of a wooden tank. ”

“ Beds should be well covered before the sun has left them in the afternoon, and not opened in the morning until the sun is well up. Seeds of vegetables for early planting, and those of annual flowers may be sown, and cuttings of green-house and bedding plants started in pots. Such a bed will also be a favorable place for the propagation of grape eyes, in which an experienced person will often succeed better by this humble means, than with the best designed and most conveniently arranged propagating house. ”

“ It is true that a house of a given size cannot as soon be brought to the required temperature after the fire is first lighted, as by other modes of heating, but when once in full operation greater regularity is maintained, and if the fire should by any neglect go out, heat is still radiated, often for several hours, before the pipes become entirely cold. ”

“ Greater strength of the roof, enabling it to resist pressure from accumulated snows, without the necessity of supporting columns under the rafters, which are indispensible under a straight roof of considerable span, to prevent its settling down, and the opening of joints in glass and wood work, admitting the cold air from without.
A good proportion for a grapery or conservatory, is twenty feet in width by fifty feet in length. We think the width should never be much less where the roof is of double pitch. Single pitched houses should not exceed sixteen feet in width. ”

“ There are two entrances to the boiler vault, one from within by a concealed trap-door, and the other from without. The house will be heated by hot water pipes.
There will be neither shelves nor tables in the house. The plants will be set either on or in the ground, and the whole interior made to resemble as much as possible a flower garden. The plants will thus be easier seen, better enjoyed, and more appreciated than if placed either on tables or staging. In any well-designed house, the plants look and grow infinitely better upon flat tables ”

“ Again, flues generally require more fuel than a hot water apparatus, and moreover, they are unsightly in an ornamental house, and with the best care in their construction and management, they do not give entirely satisfactory results.
Earthenware drain-pipe is frequently employed for flues, and when care is taken to prevent their cracking by the excessive heat near the furnace, they answer the purpose very well. When properly secured at their joints they prevent the escape of gaseous matter more perfectly than brick flues. ”

“ The principle objections to tank heating, as usually employed, are an excess of bottom heat and a deficiency of atmospheric heat, with a superabundance of moisture when the vapor from the tank is not properly excluded from the house. Tanks should be covered with some good radiating material, as slate or metal. If slate is employed, the joints should be carefully and effectually cemented. ”

“ An extensive grower of pot plants, from information carefully gathered among his fellow nurserymen, estimates that the plant trade of the vicinity of New York reaches nearly the sum of $200,000 annually, and this for plants mainly employed as "bedding plants," in the decoration of gardens and city yards, leaving entirely out of the question, those for winter culture at windows and in green houses, as well as the immense stock of the growers themselves to supply the demand for cut flowers. ”

“ In the centre is a large bed of earth used for grapes in pots, vegetables and plants. A portion of the roof on the south side can be raised when it is desirable to [Pg 59] harden off the plants in spring. The foundation is of wood, locust posts being used, with boards nailed upon both sides and coated with coal tar. The house is forty one feet long and sixteen feet wide, and is heated by a tank constructed as follows: brick piers are built three feet apart on which are laid common blue flag stones six feet long and two feet wide. ”

“ It is evident that while the required supply of heat for the bottom is uniform, and that for the top exceedingly irregular, both objects cannot be properly secured except by a separate supply of heat for each. For these reasons we would employ a hot water pipe or pipes, passing around the house, on the same level with the tanks, supplied with a valve to regulate the heat at pleasure, or a brick smoke flue constructed in the usual manner. ”

“ The general plan of Horticultural structures may be as perfect as possible, but if the details are not well carried out, and especially if the workmanship be not good, they will prove a source of never-ending vexation and expense. Insecure foundations, ill-fitting doors and ventilators, imperfect glazing, and inferior workmanship of every description, are evils that skillful gardeners have to contend with, and upon whom the consequences of such defects usually fall, when they should be placed upon the shoulders of the constructor. ”

“ It was desirable to have the house raised or appear higher owing to the slight depression of the ground at the site, and for this reason the border was all made above the surface two feet and a half in height, composed largely of decayed sods, with an addition of muck, coal and wood ashes and a small quantity of stable manure. It has been found to work admirably, and preserve an even moisture throughout. Elevated borders are highly recommended by some exotic grape growers, and our experience with them is much in their favor. ”

“ While it is desirable that they should be so on extensive places where much accommodation is required, in grounds of moderate extent many advantages are gained by having the houses connected. Facility for heating and management, protection of those houses requiring the most heat, by those kept cold or at only moderate temperature, and the ease with which all departments may be visited by the owner, are all obtained by such an arrangement. In the present instance the Green-house occupies a position east and west, and is protected on its north and most exposed quarter by the Grapery. ”

“ It is an excellent rule, that what is worth doing at all, is worth doing well; and it is just as applicable to horticultural buildings as to any undertaking in life. Rough hemlock lumber, rudely put up and whitewashed, would be a cheap mode of construction, which might be tolerated on a merely commercial place, but would illy correspond with neatly-kept private grounds, however humble and unpretentious they might be. ”

“ Hot Water Pipes.—It is generally conceded, among practical men, that the circulation of hot water in iron pipes is the best known method of heating plant houses. The property which heated water possesses of retaining for a considerable length of time its heat and transmitting it to the pipes at long distances from the boiler, renders it a most effective agency for such purposes: A perfect control of the moisture of the atmosphere, by means of evaporating pans attached to the pipes ”
