all talk to the contrary notwithstanding.

CHAPTER VI.

ATMOSPHERE AND TEMPERATURE.—INSECTS.

The proper regulation of the atmosphere as to moisture and temperature, is one of the most important points to be observed in cultivating plants in the parlor, or window-garden. Plants will not flourish, bloom, and be healthy, in a dry, dusty atmosphere, even though the best of care otherwise may be bestowed upon them; hence it is that those who attempt to raise plants in their dwellings meet with so little success. There is an immense contrast between the atmosphere of a well regulated green-house and that of an ordinary dwelling. In the green-house, the atmosphere is moist and well-tempered to the healthful growth of plants; while that of the parlor or sitting-room is invariably dry and dusty, and plants will not flourish in it as they would in the conservatory. If the dwelling be heated by coal, there is more or less gas constantly discharged into the air of the room, which is of itself enough to destroy vegetation, or make it sickly. Houses heated by steam, are better adapted to the cultivation of plants.

All plants will not flourish in the common temperature of a living-room; some require a low temperature, and others need a warmer one. The following plants require a temperature of from 70° to 80° in the day-time, and 55° to 60° at night Begonias, Coleuses, Calceolarias, Bouvardias, Ferns (tropical), Hibiscuses, Poinsettias, Tuberoses, Heliotropes, Crotons, Hoyas, Cactuses, all kinds, Caladiums, Cannas, Palms, Orange and Lemon Trees, Geraniums, etc.

The following will do well in an atmosphere ranging from 50° to 60° by day, and 40° to 45° by night: Camellias, Azaleas, Oleanders, Roses, Carnations, Callas, Ivies, Abutilons, Jessamines, Holland-bulbs, Lily-of-the-Valley, Primroses, Violets, Verbenas, Chrysanthemums, etc. Plants will flourish better in the kitchen, where the steam and moisture from cooking are constantly arising, and tempering the atmosphere, than in a dry, dusty sitting-room; hence it is that we find "Bridget" sometimes cultivating a few plants in her kitchen window, that are envied by the mistress of the house, because they are so much finer than those in her parlor or sitting-room.

If a pan of water is set upon a stove in a room where plants are growing, it will help to materially relieve the dryness of the atmosphere. But most all kinds of house-plants will do fairly in a uniform temperature, from 70° by day to 55° by night. Careful observation of the habits and requirements of different kinds of plants, as they come under our care, will greatly assist the cultivator, and in a short time he will be so conversant with their various habits as to know just how to properly treat each and every plant in his collection.

INSECTS UPON PLANTS.

The little green insects so frequently seen on house-plants, are called aphis (plural aphides), plant-lice, or green-fly. They feed upon the tender growth of plants, especially the new leaves, and will rapidly sap and destroy the life of any plant if allowed to remain undisturbed. In the spring these insects abound in great numbers on the plants in green-houses and parlors, or wherever they may be growing, and the remedy should be promptly applied. The greatest enemy to the green-fly is tobacco smoke, made by burning the stems, the refuse of the cigar-maker's shops; allowing the smoke to circulate among the leaves to which the insects are attached, will readily exterminate them. Place the infested plant under a barrel, an ordinary cracker barrel will do, and put under it a pan of burning tobacco, slightly moistened with water. Leave the plant in the smoke for fifteen or twenty minutes, after which remove it. If one "smoking" fails to destroy the insects, repeat the dose three or four times, once each day, until they are completely exterminated.

A strong solution, or "tea," made from soaking tobacco stems in water, and syringing the same over the plants, will effectually destroy the little pests, and not injure the plant in the operation.

CHAPTER VII.

WINTERING PLANTS IN CELLARS.

Many plants, such as Agaves (Century Plants), Oleanders, large Cactuses, etc., that have grown too large to be accommodated in the sitting-room or conservatory; can be successfully wintered in any moderately dry, frost-proof cellar. After placing these large plants in the cellar, it will not be necessary to give them any water, the object being to keep them dormant all winter, which can be done by keeping the soil as dry as possible, but not so dry as to allow the plants to shrivel, or become withered. Large plants of the kinds mentioned, often form desirable ornaments during the summer time, but it is impracticable, in most cases, to bring them into the house in winter, but they can be kept for years by cellaring through the winter as stated. Large Geraniums, Salvia and Heliotrope roots, and even Tea Roses, and Carnations, can be kept moderately well in the cellar by trenching them in dry, or moderately moist sand. Thus many choice specimens of these plants that we are loth to pull up and threw away when winter approaches, can be successfully kept over until the next season. It is a needless expense to purchase a stock of new plants for the garden every year, when we can winter many of the old ones in this simple and inexpensive manner. The leaves of all deciduous plants should be removed before they are put away in this manner. The foliage should remain on the Oleanders and Carnations.

CHAPTER VIII.

THE LAW OF COLOR IN FLOWERS.

The public are so often duped by a set of travelling frauds, who make it their business to represent themselves as being the sole proprietor or agent of some "wonderful" kinds of plants, bulbs, or seeds, which possess the virtue of being remarkably distinct from anything ever seen or heard of before, that many over-credulous ladies or gentlemen fall victims to the unprincipled sharks. Did you ever see any one who could sell rose bushes that would certainly bear blue roses, or plants of the Verbena that produce yellow blossoms, or Tuberose bulbs bearing scarlet flowers? If you have not, you have something to learn, and many have paid dearly for experiences of this kind.

There is a natural law of color in flowers, that the varieties of a species invariably present a certain range of colors. To attempt to introduce a new and distinct color, as for example a blue rose, into a family where the colors are always white, red, and yellow, is an impossibility, and any one who claims to do this, may be set down as a swindler.

Much credit is due Mr. Peter Henderson, an eminent florist and seedsman of New York City, for the vigorous methods employed by him in exposing frauds of this kind, whenever his attention has been called to them. We quote from an article written by Mr. Henderson on this subject, some years ago: "It has long been known among the best observers of such matters, that in certain families of plants, particular colors prevail, and that in no single instance can we ever expect to see blue, yellow, and scarlet colors in varieties of the same species. If any one at all conversant with plants, will bring any family of them to mind, it will at once be seen how undeviating is this law. In the Dahlia we have scarlet and yellow, but no approach to the blue, so in the Rose, Hollyhock, etc. Again in the Verbena and Salvia, we have scarlet and blue, but no yellow. If we reflect, it will be seen that there is nothing
