The annexed figure represents a design for an ornamental flower-stand, to be made of wire, which we commend to workers in this material. Where a greenhouse is well-managed, there will be no difficulty in furnishing it with a succession of camellias, roses, geraniums, fuchsias, asaleas, calceolarias, Ac. Ac, and it should be the aim of the possessor to preserve the brightness of the scene all through the year. The moment a plant goes out of bloom, it should be removed, and its place supplied with another; for, as to rearing plants in such situations, and in dry rooms, it is wasting one of the best opportunities which art affords us for a display of successive pictures. As well might the actors dress and rehearse before the audience, as a collection of plants be allowed to present themselves in all their preparatory stages to the eye of the visitor or the host. We do not mean by this, to prevent the window culture which gives many so much pleasure Washihgtov. D. C. Dear Sir: I thought of you, to-day, when I received from the Professor of Chemistry of Georgetown College, a great and valuable vegetable curiosity - the greatest, perhaps, in | America, in the shape of an enormous Truffle found in Virginia. I showed it to Mr. Mason, Commissioner of Patents, and produced quite a sensation, as they had published in their report for 1854 only an account of the Piedmontese truffles, not dreaming that they existed so close at hand.

We may now hope to have Strasburg pies as soon as some American makes the fois gras. My Virginia Truffle weighs one pound eleven ounces, dried, giving double that weight green. It would have sold, in Covent Garden Market, for nine dollars 1 [A similar report was circulated some years ago, to the effect that one of the foreign ambassadors at Washington had discovered the Truffle in Virginia, but it was never till now followed by a verification. It has been generally believed that this delicious esculent was not cultivable; more recent information leads us to believe that, like the mushroom, it may be artificially propagated; Dr. Lindley says so; and a Frenchman has lately asserted, without sufficient data, that the Truffle is the result of the stinging of roots of oak-trees by the Truffle fly, which Dr. Lindley denies. We shall probably know more of this ere long. - Ed].
