growth. As a high temperature causes a premature and unhealthy growth it is advisable to keep up a healthy atmosphere of from 55° to 65°, with an increase of a few degrees in sunshiny weather, when a little air, if only for a very short time, should be admitted; but be careful to avoid draughts at this early period of the year. All growing plants to be watered at the roots only, being careful not to allow any water to lodge in the axils of the leaves to cause decay. To preserve the roots of some Orchids in a healthy state it is necessary to grow them on blocks of wood; the blocks to be made proportionate to the specimens they are intended to bear; and the heel of the plant to be placed close to the end of the log, to give as much space as possible for the plant to grow upon. The following thrive well on blocks without moss:—Barkeria spectabilis, Leptotes bicolor, Phalænopsis amabilis, and Sophronitis cernua, the Brassavolas, the Cattleyas, nearly all the dwarf Epidendrums, all the Lælias, and nearly

all the dwarf Maxillarias and Oncidiums, and all the Schombergias.

FORCING-HOUSES.

Cucumbers.—Attend to the thinning and stopping, and impregnate the fruit blossom when open.

Figs.—Care to be taken that cold currents and sudden changes of air are excluded from the trees. The roots to be well supplied with water, and the trees to be occasionally syringed overhead.

Peaches.—When set, thin the fruit and shoots as required; to be done gradually, a little at one time, to prevent any sudden and injurious change in the system of the tree. A liberal supply of moisture to be kept up, with a temperature ranging from 55° to 65° and 70° by sunheat. A drier atmosphere is advised for trees in bloom; the bloom to be thinned if the trees are weak; and if shy setters, to be artificially impregnated, using a camel-hair pencil for that purpose.

Pines.—Be watchful about the bottom heat, and lose no time in raising the pots nearer to the surface if an approach to a burning temperature is apprehended. To be thoroughly watered when they require it, and to be syringed overhead in the morning and evening of every clear day unless the plants are in bloom, or ripening their fruit. Any crowns, suckers, or small plants not well established will do well in a pit or frame on a bed of leaves, or well sweetened dung, where they will make a rapid and vigorous growth during the summer.

Vines.—Attend to last week’s instructions as to stopping all laterals, &c., and thinning the bunches in good time; and tie up all the principal shoulders with soft strands of matting. Never allow the head or hand to touch the berries. Give them plenty of air-moisture during their swelling season; to be discontinued when they begin to colour. Shy-setting sorts—such as the Black Damascus, Cannon Hall Muscat, &c.—will set better by thinning the blossom-buds before expansion, by which a more regular and compact bunch will be produced. Late Vines should be pruned and dressed; and if not frosty the lights to be removed, which will retard their breaking, and benefit the trees.

FOURTH WEEK.

GREENHOUSE AND CONSERVATORY.

During continued frosty weather fires must be kept up in these houses, and then particular attention must be given to the New Holland plants, Heaths, and such like, which are impatient of heat, that they do not suffer from want of water. Be sure that the ball is thoroughly moistened at least once a-week.

PITS AND FRAMES.

Amongst climbers, Calampelises, Cobœas, Lophospermums, Maurandyas, Rodochitons, and Tropæolums, deserve attention at this time, increasing them by cuttings or by seeds. Some annuals are also worthy of attention, such as Brachycomas, Phloxes, Portulaccas, Schizanthuses, with others which may all be forwarded in heat. Whoever has not yet attended to the propagation of plants for bedding out, should now begin, without further delay, to put in cuttings of Fuchsias, Verbenas, Heliotropes, Petunias, Salvias, Scarlet Geraniums, &c., to have good plants in May and June. All straggling and weak shoots to be topped back to form robust, bushy plants.

STOVE AND ORCHID-HOUSE.

Some of the stove plants that have done blooming should be cut back, such as the Eranthemum pulchellum, Euphorbia jacquiniæflora, Geissomeria longiflora, Gesnera lateritia, Justicias, Linum trigynum, Poinsettia pulcherrima, and others. A bottom heat will be necessary when they are repotted, which may be done in about three weeks or a month. Such of the most forward plants, as they require shifting, to be attended to. The condition or fitness for this must, in a great measure, be determined by the progress the shoots and roots have made.

FORCING-PIT.

Continue to introduce plants of Azaleas, Hyacinths, Heliotropes, Hydrangeas, Kalmias, Sedums, Lilacs, Narcissus, Pelargoniums, Pinks, Rhododendrons, and Roses

in varieties. A batch of last year’s young Fuchsias, Erythrinas, and Salvia patens, to be shaken out, repotted, and placed in bottom heat. Sow Balsams, Cockscombs, Globe Amaranths, &c.

FORCING-HOUSES.

Cucumbers.—Attend as previously advised to thinning and stopping, set the fruit blossom when open, keep the inside of the frames watered with warm water, and apply some occasionally to the roots. Water overhead on fine days, shutting up with 75° or 80° of heat.

Cherries.—They will be benefited by frequent syringings at all times except when in bloom. Air to be given on all favourable occasions, shutting up with as much solar heat as possible. Keep down the green fly and look well after caterpillars.

Figs.—Maintain a kindly humidity, but do not syringe overhead, except on very fine days, as too much moisture is apt to cause the fruit to drop off or to turn yellow.

Peaches.—Tie in the forwardest shoots in the early-house as they advance; gradually disbud and thin out all the shoots that are not wanted; thin the fruit but not too much at once, and, with water of the temperature of the house, syringe the trees that have set their fruit. Remove large shoots cautiously, and reserve, in tying and disbudding, merely sufficient wood for next spring.

Pines.—The atmospheric heat to be gradually increased in the fruiting-house, and the plants to be frequently syringed, taking care that no water is allowed to lodge in the hearts of the plants. The plants swelling their fruit to be watered occasionally with clean soot water, air to be admitted on every favourable opportunity, but cold draughts to be avoided. A good heat to be kept up in succession-pits worked with linings.

Strawberries.—To be placed near the glass with plenty of air, and in favourable weather to be liberally supplied with warm manure water, and the surface of the pots to be frequently stirred.

Vines.—As soon as the first swelling is completed, and the stoning process commences, allow a little more liberty to the laterals to induce a corresponding increase of root action. All shoots to be properly trained up; but none

to be allowed to touch the glass. All small bunches to be removed when in flower. When the fruit is set, the heat by day may be allowed to rise from 70° to 80°. See to the border coverings, if out-doors, as also border waterings, if in-doors. Be careful when admitting air to the early Vines, to avoid cold currents and changes, for in the space of an hour we have sometimes strong sunshine, sleet or snow, and cutting winds. Vines in pots to be
