The most complete establishment for this system of culture that it has yet been our good fortune to see is in the grounds of Wm. Beech Lawrence, Esq., at Newport, Rhode Island, and under the care of Mr. Alfred Chamberlain. The house is a lean-to, 300 feet long, built in the best and roost substantial manner, back and front walls of stone, back wall 12 feet high and front 5 feet, (two feet stone arch, and front glass ventilators, 3 1/2 feet by 3 feet') the house is 13 1/2 feet wide, the trees in pots being grown in a pit five feet high and seven feet wide, the larger pots being placed nearer the back; the roof is made of seven-by-nine extra thick horticultural glass; the ventilation in the roof is effected by means of 3 1/2 feet by 3 feet sliding sash; these, as well as the front ventilators, in which the glass is larger, are worked by means of an iron crank - an ingenious invention of Mr. Chamberlain, which for completeness and simplicity exceeds anything that we know of. The entire house is heated by hot water pipes, with one of Wethered & Cher-evoy's patent furnaces, and is divided by glass partitions into sections of thirty feet; the floor is paved with brick, and around the pits are shelves for the smaller trees, together with a shelf eighteen inches from the roof, on which it is proposed to-stand some 600 strawberry pots; thus bringing into use all the available space, at the same time furnishing the necessary facilities for approaching each tree.

The first and second divisions are intended for growing pineapples; in the third are 200 pear-trees, in various sized pots: here are Doyenne d'Ete, Duchesse d'Angoul&me, Louise Bonne de Jersey, Tyson, and I know not how many other varieties, all on the quince; on some there was a fair show of fruit, although only potted last October. The size of the pots varies from eleven to fourteen inches, the first-mentioned size being esteemed most desirable, but with many of the trees it was found impossible to cut away enough of the roots for an eleven-inch pot without endangering the tree; it is Mr. Chamberlain' sintention to use eleven-inch pots altogether. A noticeable feature was, that the aperture at the bottom of the pot was permitted to remain of the usual size, and not enlarged according to Mr. Rivers's directions. The trees were all well mulched with moss, and have made a fine growth. The pears are carefully pinched in every five weeks. Water is given every other day, and the syringe used daily in the evening, an abundance of air being permitted at all times.

The next division embraces the peaches, of which there are 260 pots making a most luxuriant growth; here are to be seen peach-trees growing 'in wire-baskets, surrounded with moss and trained in every imaginable shape.

Mr. Chamberlain is entitled to the credit of having been the first to grow trees in hanging baskets; some of the peach-trees are trained as espaliers over the back walk. The same treatment is given them as the pears, except that they are left unpinched, the pinching off of the terminal buds having been found to burst the fruit-buds and destroy the prospect of the next season's crop: the branches are intended to be tied down, and the tree made to assume a pyramidal shape.

In the next apartment we find 200 cherries, 100 apricots, and 60 plums, all freely pinched in, and trained into pyramidal shapes. A number of apples on the Paradise, in eight-inch pots, together with figs and strawberries, complete the assortment; but as curiosities, currants, raspberries, and even filberts are found cultivated in pots. The varieties of strawberry to which the preference is given, are Boston Pine, Wilson's Albany, Jenny Lind, and Scott's Seedling. On the back wall are the potting room and the pot rooms for keeping the pots together, with rooms for assistant gardeners, and mushroom pits. The mushroom spawn is procured from a New York house, and grown in the dark: about six weeks after planting, the mushrooms are ready for market, and the demand is good.

A number of turtles and frogs are kept among the pot trees, and are found exceedingly useful in devouring numerous insects. The arrangements for watering are very complete, and force pumps and hose so introduced that no tree is likely to be overlooked.

In the greenhouse were found a number of Bananas just imported from Cuba, in fourteen-inch pots, ready for forcing. The fruit is intended to be forced, and under Mr. Chamberlain's care we should have no fear of the crop, he having had the benefit of two years' experience with Mr. Thomas Rivers, of Sawbridgeworth, England. The cost of his buildings was about ten thousand dollars.
