If the pots are full of roots, as they often are on being received from a nursery, - should be shifted into pots a size larger, in a soil consisting for the most part of turfy loam, with a small quantity of turfy peat or half-rotten sticks, added to it They will, of course, receive regular watering through the summer, and during the hot season be placed where for six hours or so, during midday, they can be protected from the sun.

The whole of the other plants may be turned out into a half-shaded border, which has previously been deep dug and lightly manured, till the end of August, "when all but Spircea, Deutzia, Weigela, Ribes, and, in short, all but deciduous shrubs, should bo prepared for lifting into pots. This preparation coneists in giving them a thorough soaking with water a few hours previous to taking them up, without which they will suffer materially under the operation. Put them in as small pots as possible, place them in a situation where they will get only the morning sun for some days, and pot or syringe, and place them gradually in the full light as they seem able to bear it. They will "miss the change" but very slightly, and besides the requisite labor attending plants kept in pots the whole season, will be much better plants. The exceptions to the above (deciduous shrubs) are best left in the ground till their leaves are ready to fall, say about the end of September, as, if they are lifted before the wood is ripe, they seldom flower freely.

The plants should be all housed before the weather becomes even "white frosty," and at the return of spring, or, in this latitude, early in May, set out of doors a few days, then cut down as is usual with Geraniums, and afterwards planted out to grow, as in the previous season. When the plants turned out of doors have begun to grow, a few young shoots of each kind should be taken off and struck. Young plants thus raised will come into flower a few weeks after the old ones are gone out, and will besides come in useful to retain wherever the old ones grow too large.

Besides the plants I have above noted as permanent green-house plants, there are many special things that cannot be dispensed with. The Camelias Double White, Candidi8sima myrtifolia, and Lady Hume's Blush - are essential in a collection of boquet flowers; nor can Azaleas indica alba, Phameciae, and Smithii. These can be successfully grown with the other plants by giving them an open, turfy soil, well drained, and an abundance of water while growing, little when comparatively at rest, and partially shaded in summer time.

The Horse Shoe or Scarlet Geraniums, Geranium Comptonianum, the Oak-leaved, and Rose-scented, are essential ingredients in my ideas of a winter boquet; and in the spring of the year of the lighter colored Cinerarias and white and scarlet Verbenas. Cuttings of all these should be put in expressly for this purpose early in the summer and grown for a few months in the fall. Mignionette and Phlox Drummondii should also be sown in pots with these, for the same object.

The Rose must not be forgotten. For a small green-house, I would select the following kinds as blooming very freely under very common treatment - Cels, white; Devoniensis, pale lemon; Madame Bosanquet, creamy white; Souvenier de Malmai-son, rosy white; Caroline, salmon white; Lyonnais, salmon; Common Daily or Monthly China, pink; Hermosa, rose; Carmin Bean, purplish rose; Agripini and Louis Philippe, crimson. Roses for blooming early in winter, should in all cases be turned out of their pots, and lifted in August, in the same manner as already described for a class of plants. When they are re-potted, a good proportion - say one-third of coarse stable manure, with the turfy loam employed, will be of great service.

There are many other plants, and tribes of plants, which are indispensable to make a green-house gay in the fall, winter, and spring, as Chrysanthemums, Cactuses, Hyacinths, Lechenaultia, Pimelia, etc. But I have thought it best to confine myself in this article strictly to your correspondent's object - "plants which will serve at once to adorn the green-house, and to cut for the centre-table".
