Raffia, the lower epidermis of a ^Madagascar jjalm (Raffia niffia). peeled in narrow strips and dried, is extensively used in America and Europe for tying vines, flowers, celery and in graftage. It is soft, strong enough for the purposes, and not quickh' altered by moisture or temperature. Because of its cheapness it has displaced bass in nurser}' and green- house jiractice. Its chief fault is its ten- dency to roll when dry. Moistening overcomes this. As received from abroad, it is in jjlaits or skeins. Fig. 185 shows one of these unra^'eled. 293. Grafts in moss and charcoal. âR. C. de Briailles has simplified grape bench grafting by the following plan : .-\s the grafts are made they are placed in a box containing a three-iijch layer of damp moss and charcoal (three to one) and covered with another layer about half as deep. So on till the box is nearly full, the remaining space being filled with packing. The box may thus be ship- ped or the grafts treated at once by a room warmed to 50 or 60 FIG. 185â SKEIN OF RAFFIA being placed in Within 24 hours the buds start lo swell, and in a week may be one-half inch long, when the moss is remo^â ed for inspection. If all is well, new packing is applied about half as thick. " If any grafts are rotting, the whole are exposed for 24 hours and then covered. If too dry, a thicker layer of packing is added and the box stood in water of the room temperature till the packing is moistened n
