Plants. - A simple method of conveying shrubs, and young trees, from distant climates, has lately been published by M. Charpentier De Caussigny. He directs a box to be provided, of a sufficient capacity, according to the number of plants intended for transportation. Some light earth, moderately moistened, is then to be spread at the bottom, to the thickness of fifteen lines, or from one to two inches. The young trees should now be taken out of the ground, together with their roots, and the soil adhering to them : after cutting off the extremities of the roots, and also of such branches as are in a growing state, they must be carefully placed between two strata of earth ; when the box should be closed. As the plants are apt to become dry during the voyage, in consequence of which their vegetative principle would be endangered, it will be necessary to perforate the lid of the box with several holes, through which they may occasionally be supplied with water; and then be closed with wooden pegs, in order to secure the plants from the effects of cold and moisture. This method has been successfully practised by M. de C. with the most delicate shrubs, which uniformly prospered, after having lain several months in close boxes.
