Such methods will prevent the necessityof bridge grafting except in cases of unusual FIG. \i -VARIOUS STYLES OF GRAFTING KNIVES A, closing blade propagating knife with bone bark lifter; B, C, nursery graftingknives, blades stationary; D, pocket grafting knife. \\hen the girdles are narrow—say only one to —no bridging may be necessary. In such cases,however, it is well to err on the safe side by covering thewound with grafting clay (half clay and fresh cowmanure) and bandaging this in with cotton cloth, or byusing grafting wax as described above. Often suchwounds will heal over in a single season. 301, Root grafting, perhaps the most generally prac-ticed nursery method, is usually performed by means ofthe whip or tongue graft, a method employed only withsmall stocks generally one or two years old. It is often-est done during winter in a cool, humid room. Shouldthe air be too dry or too warm, the grafting wood may beinjured by drying. Never should the work be done neara stove or a radiator for this re
