Whichever of these modes of grafting is adopted,the graft must be fastened in its place by tying, forwhich purpose a strand of bast-matting is commonlyused. The access of air is further prevented bymeans of clay, which has been worked up with aLittle chopped hay, horse or cow dung, and water,and which is applied to the place of jimction so asto form a ball, tapering both upwards and down-wards.
