It is a delicate matter to find fault with those, who with great labor and industry have exerted themselves to add to the interest and attractions of our Horticultural exhibitions and State Fairs - especially when the great mass of the people show so little enterprise in supporting them. It can certainly do no harm, however, to point out the difference between good and bad taste, and to enable the industrious and ingenious to expend their labors to better advantage. Good taste can never deviate from- fitness and good sense; hence images of the human figure, built, like cobble-stone houses, of roses and asters, are entirely out of place. Flowers are light and decorative merely, and can never be properly used in constituting the solid material of heavy bodies. The human figure may be imitated in stone or plaster, and wreaths of flowers used sparingly in decorating it. but never in building up its solid portions. The same objection, that of unfitness, applies to the construction of banners, stars, and other odd conceits, of flowers. There must be a natural suggestion of the one from the other, which is not the case when the American flag is made of verbenas, as we lately saw a most ingenious example at a State fair.

Temples and alcoves of flowers arc also objectionable for the same reason j but temples and alcoves decor uted properly with wreaths of flowers, not as a part of them, but as exterior ornament merely, may be in perfectly good taste. We have seen some beautiful objects in the form of baskets of flowers; but when the baskets themselves appear to be com posed entirely of flowers, instead of being merely filled with them, or wreathed by them, the incongruity is at once apparent. At the late State Fair at Utlca, were some very ingeniously constructed figures in human form, but in most singular bad taste, and which must have cost the exhibitors whole days of labor - while close beside them stood two handsome empty vases, which might have been in a moment rendered infinitely more pleasing by throwing promiscuously into each an armful of flowers. At the late Philadelphia annual show, there were some very richly wrought specimens of flower temples; but we regarded with a great deal more interest the simple structures made of wire, and beautifully covered with climbing plants, which had grown up and covered thern, and were then in full bloom.
