Modelling and Making Paper Flowers. This art is so elegant, clean, and delicate, that the most refined lady need not scruple to practise it; it requires only to examine Flora's gifts with exactness, and delicacy in handling the materials, to bring it to perfection. The following instructions will be found sufficient for the modelling a Pomegranate and Burige's Rose Campion. THE POMEGRANATE.-This is a beautiful flower to model, and is of a brilliant scarlet, of a peculiar tint, and will amply repay the pupil for the care be stowed in making it. There is another beautiful and delicate variety of this flower, which is white, much more crimped at the edges, and most richly marked with scarlet; it is rather scarce in this country, but an elegant flower for a vase. This flower requires but two patterns for the petals, and about 35 to 40 form a flower-20 of No 1, and 16 of No. 2. Place the petals No. 1 on a piece of crape, fold them in two, and crimp between the fingers and thumb the upper part of the petals. Fold them together lengthways, and bring the upper edges for ward. Proceed in the same way with petals No. 2. Then take a piece of middling-sized wire, bend the end a little, and roll round it some paper to the shape and size of a plum-stone, and cover with some scarlet paper; after which, fix the petals No. 1 with some cement and silk in rows of threes and fives together. Then proceed with petals No. 2 in like manner; after which draw on the calyx (which may be purchased ready prepared) of nearly a similar colour to the flower. Finish by preparing the thickest wire by covering it with reddish brown paper for the stem, in imitation of bark (or woody stalks); then cut the stalk of your flower about an inch long, just sufficient to attach it to the stem. This flower grows in trusses of three and four together, with two or three buds above them (which may also be obtained ready prepared), and which will give great effect to its appearance. BURIGE'S ROSE CAMPION.-This species of flower is a beautiful scarlet, and easy to model. It is a native of Asiatic Russia, an herbaceous perennial, very pretty and ornamental, and displays its rich scarlet flowers in the month of July. This flower is peculiarly grace. ful on account of its lanceolate leaves; hence it has been selected as a good flower for grouping. This flower requires but one pattern for the petals, namely, to show the size, and has five in number. You must avoid cutting every petal alike, but vary them more or less (as seen in the whole flower in the engraving). After having cut the petals in bright scarlet paper, form fine veins on them, as seen in diagram, with a tint mixed of carmine and indigo, and placed on with a fine sable brush. Con ing with the feet. Place at onee over from frost is past, remove the protection, Let only one stem rise from a plant, and nip all laterals as they appear. Never allow the plants to suffer for want of water; and as soon as flowerbuds are formed, mulch the beds with rotten manure. I prefer this to giving manure water, as the latter, unless ap Culture of Hollyhocks.-The hollyhock is not so generally grown as its decorative qualities entitle it to be, says a correspondent in the Gardener. When grown amongst shrubs in situations moderately sheltered, few plants produce a finer floral display during the autumn months. The great drawback to its cultivation is the liability of the plants to get broken with the winds; but if secured when 18 inches high to suitable stakes, this objection is at once got over. At planting time give each plant a few spadefuls of rotten manure, and if possible a little fresh soil; press the earth firmly round the plants; and if the ground is dry, give a good water-plied with judgment, has a tendency to ing. In due time, stake each plant, and make the plants grow by fits and starts, as the stems advance in growth, secure thereby causing irregularity in the build them thereto with strong ties of mat- of the spikes, a fault which neither ting. If the above simple hints are at- length of spike nor size of blooms will tended to, the result in most instances compensate for. In most instances, two will be satisfactory. flower-buds will start from the axil of each leaf; nip out the smaller of the two; and in any case of crowding thin to the requisite number. During the three weeks preceding the show, the spikes must be protected from rain and strong sun. This, in the case of the hollyhock, is not so readily accomplished, but it is necessary to the production of clean spikes; and the cultivator must not neglect, as by doing so he will destroy his chance of attaining the end in view. When Holyhocks are grown for exhibition, they must have a plot of ground devoted to themselves; let the situation be as sheltered as possible, but never near to anything that would in the least obstruct the noonday sun or a free circulation of air. To produce spikes such as are seen at some of our horticultural shows requires a rich soil. To secure this, let the ground be trenched in autumn, adding, as the work proceeds, a liberal supply of good manure. When the trenching is complete, give the surface a dressing two or three inches thick of the best manure procurable; the winter rains will wash the best parts of it into the soil, and when planting-time comes, a slight forking is all that is required to make the bed in readiness to receive the plants. The plants should not be put out until all danger from severe frost is passed, say the end of March or the beginning of April. Let the plants stand three feet apart in the lines, and five feet from line to line." When finished planting, if the ground is moderately dry (which it should be, as it is a bad plan to plant when the soil is over-wet), make the surface rather firm by giving the whole a gentle tread Culture of the Chinese Primrose. The large purple and white-fringed varieties of last season being a great improvement both in size and colour, will now more generally commend this favourite flower to the notice of the public. About the middle of March the seeds are sown in a pan of light rich soil, in gentle heat, in a cucumber frame, or in any other warm place, and when plants have obtained their rough leaf, to be removed to the greenhouse, and placed on a shelf or trellis as near the glass as possible, to give them strength and dwarfness. When fit, they are potted off singly into small 60-sized pots. About the end of May they are shifted into large 60-sized pots. using compost of have even candles. Now, the reason is this: the hydrogen of the gas, or oil, or tallow unites with the oxygen of the air, taking eight measures of oxygen to one of itself, to form nine measures of water, which is deposited on the windows and walls if provision is not made for its escape; then the carbon unites with a portion of the oxygen to form carbonic acid gas. equal portions of turfy leaf-mould, peat, | this takes place in every room where we and silver-sand well mixed together in a rough state; the drainage must be carefully looked to, or most probably, if not well drained, many of the plants will damp off and others grow weakly. They are to be placed again in the greenhouse near the glass, and to have plenty of air and room. About the beginning of July, when the plants will have filled their pots with roots, they are shifted into 48-sized pots, in the same sort of compost as before, with the addition of a little decomposed cow-dung, and if any blooms appear, they are pinched off. About the middle of August they are shifted in 32-sized pots, in a compost of two-thirds charred turf, one-third rotten cow-dung and silver-sand. When large specimens are required, they are shifted into 24-sized pots, the soil to be made quite firm around the roots, and then to be removed to a shady situation in the open ground until, if the weather is favourable, the first or second week in October, when the best-fringed and coloured flowers are chosen, and removed to shelter under glass, where air can be freely admitted to them in fine weather. By such treatment they will bloom freely from November to May. Ventilation is required in all apart ments, but especially in those we sleep in. Various methods have been used for this purpose, the most useful of which is that of Dr. Arnott, which consists in making an aperture opening into the chimney, as near to the ceiling as possible. The chief points requiring attention in ventilating rooms or houses consist 1. Of having an inlet for fresh air, and an outlet for vitiated air. 2. The air admitted should be as pure as possible, free from local vitiations, such as drains, smoke, &c. 3. When air is admitted into an apartment it should be at the lowest part, and the aggregate area of admission should be twice as great as that of the outlet. Where gas or oil is consumed for lighting a room a large amount of carbonic acid and water is generated, and Each room should have a fireplace, and particularly bedrooms, and when there is not one, some other means of ventilation should be contrived, such as inserting a revolving ventilator in the upper part of the room, over the door. Such a contrivance can be procured and fixed for about sixpence or ninepence, and when the upper sash of the window is let down for about an inch, the room will be rendered quite sweet and wholesome. Whenever persons have left a room in which they have sat for some time, the window should be opened and the door set ajar; the same plan should be pursued with bedrooms. Many persons sleep with their windows a little open, and the plan is not objectionable, except in damp weather. In high houses it is advisable to light the staircase by a skylight hung in the centre, so that it will serve for the purpose of ventilation as well. Dr. Darwin, while addressing an audience of mechanics at Derby, some years ago said: "By your exertions you pro cure for yourselves and families the necessaries of life; but if you lose your health, that power of being of use to them must cease. I fear some of you do not understand how health is to be maintained in vigour. This, then, depends upon your breathing uncontaminated air; for the purity of the air becomes destroyed where many are collected together, effluvia from the body corrupts it. Keep open, then, the windows of your workshops, and as soon as you rise in the morning, open all the windows of your bedrooms. Inattention to this advice, be assured, will bring disease on your |
