A selection for this purpose should be made from the Tea and Sourbon families, on their own roots or budded very low. Presuming the plants brought from he nursery are in the small pots they are generally grown in for sale, they should at once be laced into those a size larger, carefully and freely watered, during this and next month, cutting ff all the flower-buds they may show before September. About the middle of the latter month horten the strongest shoots, and thin out the slender ones, turn the plants out of the pots, lepriving them of some of the soil, and repot in those a good size larger, using a compost of urfy loam, sand, and manure in about equal proportions; they also like a little leaf mold; put everal pieces of broken crock in the bottom of the pot then a portion of soil; place the plant to that its surface roots shall just be covered, and then filling with the soil; put them in a situa-ion partially shaded - water sparingly, till they begin to grow - then expose them fully to the ran, and water freely every day. There they may remain till the middle or end of October, when they should be removed to a pit to prepare them for flowering. Previous to their removal, the oots should be washed, and the plants neatly tied up.

Where charcoal can be had, it will be bund of great utility in the pot-culture of Roses, broken to the size of nuts, and about one-fifth nixed with the soil; the roots delight to ramble through it, and the foliage becomes of a richer and darker green; the surface of the soil must have frequent stirrings. The plants must be care-ully examined, and whenever infested by the green-fly, the latter should be destroyed by tobacco moke, Roses in pots are wonderfully benefited by a watering of manure-water now and then, [his water is very easily prepared. Let droppings from the stable or cow-house be put into a arge tub or barrel, with water kept over them for a week or two, occasionally stirring it up; he water may then be poured or drawn off for use. Guano water also makes a good manure. A quarter of a pound of guano in three gallons of water, frequently stirred before using, will be bund very nourishing; indeed, one pound to sixteen gallons will be strong enough to use by the nexperienced, for if used much stronger than I have stated it would injure plants in pots.

In he open ground any of these liquids may be used stronger and rather more frequently. - J. H., in Gardener's Chronicle, London, July 16.

Tax Lapageria rosea, exhibited by W. J. Myers, Esq., at Chiswick, on Saturday last, has been grown in the plant-stove, where for the last three years it has never failed to flower beautifully; nd when fifteen or sixteen blooms are in perfection at one time (as we have had it) the effect is very striking. One planted out in the border of a Camellia-house has not grown any - in fact t has grown small by degrees and "beautifully less." Another planted in the border of the plant-stove last year has made a shoot twenty feet long, and is now in flower, up the rafter. We find that it grows best in pure leaf-mold, with plenty of pieces of wo state of decay mixed with the soil, and the plant kept well up in the pot or border in whi lanted.
