Like inarching, this will only be practised on the home grounds. Fig. 23 gives the method of doing the work. A scion eighteen to twenty inches long is used with one end stuck into the soil and near the top it is grafted on the stock by inserting a wedge at the top of the stock into an upward cut two thirds of the way through the scion. The long scion with lower end in the soil, holds moisture while the union takes place. The writer has grafted the grape in this way when the scion rooted below while the union was taking place above. We have also found this a certain method of grafting the peach, cherry, and plum, if the work is done very early before sap-movement commences, using a dormant scion cut the winter previous to using.

With potted plants this method is adopted with some plants by placing the lower end of the long scion in water. In this case, as stock and scion are in leaf the union is made as in Fig. 24 and the top of the stock is not cut back until the union is complete. This plan is also adopted sometimes in the open air in top-grafting, in the dormant period.
