INARCH'ING, or GRAFTING BY APPROACH, a mode of grafting by whfch branches are united together before any of them is separated from its original stem. Branches grow ing across one another sometimes unite in this way of themselves, and it is supposed— not improbably—that an observation of this cirmunstance first led to the invention of grafting. Inarchina. is practiced in cases in which the ordinary modes of grafting are not found readily to succeed, as with camellias. The stocks to be grafted upon are planted, or placed in pots, around the plant from which the grafts are to be taken. Four or five months are generally sufficient to complete the union, but sometimes even twe years are necessary. When the union is complete the scion is separated by a sloping cut from its parent 'plant. Care must always betaken that the parts to be joined together be cut so as to fit one another pretty exactly, and they are then firmly together, and SC, covered that neither air nor water may penetrate. It is desirable that they be branches
of nearly the same thickness. They should be cut almost down to the pith, but the pith must not be injured. marching is performed in spring, after the sap has begin to circu late. There arc several ways of inarching. For example, two branches of a tree may be bent so as to meet and strike upon a wound in the main stem, by which a gap will be filled up; one growing tree either from the ground or a pot, may be led to unite with another; or several suckers may be led from the ground'archwise to strike upon a point in the stein, thus bringing fresh aid to the productive part of the tree. By means such these, quiekset-hedges are sometimes thickened like a net-work, so as greatly to their appearance and protective qualities.
