In this mode of grafting hickories it is not necessary to employ the entire root or stock, if it is of large size, for a single cion; for pieces of from six to twelve inches long, containing a few lateral fibers, will answer the purpose, and it will be found, in practice, that these sections of the large fleshy roots contain so much vitality that, if the cions set in them fail to grow, they will throw up sprouts from adventitious buds during the ensuing summer. Almost any fair-sized piece of root left in the ground, when digging up hickory trees large or small, is pretty certain to throw up sprouts, this not only showing their great vitality, but that propagation by root cuttings is perfectly practicable and may be utilized whenever and wherever it may be desirable. The man who attempts to raise hickories from root cuttings must have patience, for very frequently the cuttings will remain apparently dormant in the ground one entire season before the sprouts appear above the surface. I will also add that this slow or retarded germination frequently occurs with the nuts, especially if they have become somewhat dry before planting. For commercial purposes root-grafting small stock, as described, during the fall and winter, gives promise of being the best and most practicable system of multiplying varieties; but there is much yet to be learned in regard to details, and hundreds of carefully conducted experiments may be necessary to determine the exact time, condition and mode of operation. It may be that very early grafting is better than late, or that we have not, as yet, found the best species for stocks, and that a half-ripened one will be preferable to one fully matured. Neither has it, as yet, been determined what kind of material is best in which to store the grafted roots: sand, soil or sphagnum (moss) from the swamps; or whether they should be kept very moist, or comparatively dry; very cold, or moderately warm. Here is a wide field for experiments, and a most interesting one; for the successful propagation of the hickories by any mode that will insure the perpetuation and rapid multiplication of varieties, means millions of dollars added to the wealth of the country.
