GRAFTING CLAY. This consists of two parts clay and one of cow-dung. Some persons make an addition of finely-cut hay, as being of use in preventing the Clay from cracking and falling off. These ingredients should be beaten together, and thoroughly mixed, several weeks before being required for use, and be then occasionally turned and mixed again. If a cavity is made in the top of the heap, and filled with water, the whole bulk may be kept moist for a long time. Grafting Clay is an economical composition, most useful for excluding air and moisture until a union in the stock and scion is effected.
