text: I should like to give you an illustration from my own handicraft. It is not every vine that admits the grafting process; if it be old and decayed, or if it be weak and slender, the vine either will not receive the cutting, or will not nourish it and make it a part of itself, nor will it accommodate itself to the qualities and nature of the grafted part. Hence we usually cut off the vine above ground, so that if we do not get results at first, we may try a second venture, and on a second trial graft it below the ground.
