Dear Sir - I respond with pleasure to your wishes respecting the description and management of the cold vinery, erected two years ago, at this place, by my employer J. C. Green, Esq.

The house is 74 feet long, and in other respects, the same as Mr. Van RENssElaEr's at Clinton Point, described in a late number of the Horticulturist, with the exception of there being only two rows of pillars inside, which gives a pathway six feet through the middle of the house. There are 24 vines to each roof, and 14 on each side of the pathway, being one to each pillar, making a total of 74 vines. The base soil of the borders is a tenacious, hazelly loam, resting upon an adhesive gravelly bottom. The borders are 20 feet wide on each side of the house and twenty inside, giving a breadth of 00 feet and length of 74 feet. A drain three feet deep, and filled with rough stones to the level of the lower base of the border, extends all round the outside, and also another on the lower end to convey the water off, the whole base being on a slight slope. Underneath the whole bed is a layer of oyster shells five inches deep, so that the entire borders rest upon drainage with a free outlet for water by the outside drains.

The materials made use of in forming the borders, which are not more than two feet deep, (18 inches below and six inches above the level,) are the base soil above mentioned, 60 barrels of bone dust and 40 tons of stable manure well decomposed, being about one bushel of bone to every three, and one ton of manure to every twelve square yards.

The vines were obtained from Mr. Buist of Philadelphia, and with the exception of three, were one year old. They were all planted inside of the house in March, 1850, the roots being carefully spread out and placed on small mounds on the surface, having about two inches deep of soil covered over them. They were pruned back to the lowest good eye, and when they commenced growing freely, water was administered plentifully over the house, and a humid atmosphere kept up, more particularly in dry and hot weather; excepting on cloudy damp days, the vines were syringed over head every evening, and the floor damped too or three times during the day. During the hot weather the borders were lightly covered with the refuse grass from the lawn's. The lower ventilators were not opened till the vines began to show appearand of ripening, and the thermometer kept through the day from 90° to 100° while growing freely. On dull cloudy or rainy days, with an east or south-east wind, the house was kept closed, and a little sulphur strewed over the floor to prevent mildew. The laterals were shortened in to an eye as they were produced.

In September appearances of maturity were visible, and water was gradually withheld; the lower ventilators were now opened gradually in the day time, increasing the air as ripening progressed.

After the middle of October, water was entirely withheld, at which time most of the vines had run up to the top of the house on one side, and as the beads were not stopped, down to the bottom on the opposite side. The leaves were allowed to remain on till they fell off, quite yellow and mature, leaving the canes well ripened and short jointed, most of them being three-fourths of an inch in diameter, with fine plump and well rounded buds and a uniform growth throughout the house.

They were now pruned in to about an average of six feet on the rafter, and each other eye on each side of the cane disbudded, leaving those intended for next season about twelve inches apart. A covering of straw was wrapped round them and they were tied down horizontally. The borders outside were covered with salt hay. The house was kept open except in severe weather or rain.

By the middle of March the buds showed signs of bursting, the vines were uncovered, and a good syringing given, which was repeated two or three times a day in mild, but withheld in cold weather The heads of the vines were kept down in a horizontal position till all the eyes were well burst, when they were taken by degrees, according to development, and tied to the wires, the tops being; allowed to hang pendant till all parts were equally broken. The flower bunches were now approaching towards bloom, and as it was not intended to allow the vines to bear heavily the first season after planting, most of the lower bunches were taken out to encourage the bottom side shoots to become as strong as the top ones, and on each other eye, higher up the cane, a bunch was allowed to remain. As the blossoms expanded, the atmosphere was allowed to become somewhat drier, and syringing was withheld overhead; the bunches were occasionally shaken to distribute the pollen and assist in fertilizing the stigmas. After blooming, and when fairly set, all bunches not wanted were removed. The berries, when about the size of peas, were thinned out carefully, leaving the berries on smaller kinds closer, and on the larger ones more distant; the shoulders were tied up, and the clusters pegged out.

Very little after-thinning was required. The borders were uncovered at the same time as the vines, and slightly forked over, and a dressing of compost laid over, (both inside and out,) about three inches thick, composed of three-fourths turf sods, one-fourth stable manure, and a light addition of sugar house refuse. These had been mixed the season before, and were well incorporated together.

When planted, the crowns of the roots were somewhat elevated, which enabled me to apply this dressing to advantage, as the small fibres were quite matted underneath the surface. The same treatment was adopted throughout the summer as last season, till the grapes began to color, when water over head was discontinued, but occasionally applied to the roots inside the house, to enable the crop to ripen off well. The borders outside were lightly mulched throughout the summer, with stable manure, and a thorough good soaking of water was applied three times during the long drouth.

On the second of August were cut, fully ripened, and well swelled, the first bunches, (Mulvesia and Joslin's St. Albans,) being a little under seventeen months from the date of planting-. Other kinds matured in succession; the whole crop being two hundred and sixty-two bunches, well colored, some of the Hamburghs being over two and a half pounds weight, and the other kinds being equally fine. •

From the present state of the vines, I do not hesitate to say that from six to seven hundred bunches may be taken from them next season, without injury. In pruning this fall, I have cut the side branches back to a good and plump eye, with the intention of taking two shoots from one spur, each (farthest from the main stem, for fruiting,) and one close to the base, (not to be fruited till the season after,) when the spur maybe cut back, thereby keeping the side shoots "at home," without stubbing in so close, and ensuring finer bunches. The top growth is cut to about six feet, and dis-budded as last season, leaving the canes over twelve feet long, and in good condition at the end of two seasons planting, to bear a full crop.

Hoping the above description may assist in stimulating the lovers of this inestimable fruit to erect houses for its cultivation, as no fruit-bearing plant is more easily grown, or gives greater return for kind treatment, I am yours most respectfully, Wm. ChoRltON, Gardener to J. C. Green, Esq., New Brighton, Staten-Island.

[We thank Mr. ChorltoN for his very practical and valuable communication. We would be glad to receive many more just such as this from our practical readers, who know but will not communicate their knowledge. Ed].
