A considerable amount of grafting has been done since 1949 and the results have been good. Two year old Chinese transplants are usually used as rootstocks and all grafting is done in the field. The best results have been obtained where the rootstock plant was transplanted one year prior to the grafting. The simple splicegraft, or the bark or rind graft are used, depending on the size of the scion compared to that of the rootstock, the latter technique being used when the stock is considerably larger than the scion. There is some evidence of incompatibility; thus, scions from Chinese trees, or hybrids that show a dominance of Chinese characters, give a higher percentage of takes when grafted on Chinese rootstocks than scions from the native chestnut, or from hybrids between Japanese and native chestnut. Some indications of incompatibility between European and Chinese chestnut in grafts have also been encountered where scions received through the cooperation of Dr. C. Schad, Centre de Recherches agronomiques du Massif Central, France, and Count F. M. Knuth, Knuthenborg, Denmark, were used, but in some cases these grafts were successful. Topworking, using the veneer crown graft, has been quite successful as long as sufficient sap drawers are left on the stock (Fig. 3). Inarching The senior writer has already explained in detail (2) the simple method by which blighted chestnut trees can be restored to health and vigor by cutting out blighted areas in the bark, painting them over, and inarching or ingrafting one or more basal shoots into the healthy bark above the lesion. We do this work from mid-April to mid-May, and make a systematic canvas of all the trees in all our plantations, inarching all those where if is necessary or might be advantageous. Each operation requires only a few minutes. Last year we put in many hundreds of inarches, altogether, which later showed nearly 100% "take". Owners of chestnut orchards should take advantage of this method of keeping valuable nut-bearing trees, although with cankered areas, in healthy, vigorous condition. We believe that, in cutting out the diseased bark, it is advisable to cut out also a few of the outer annual rings of wood (of course tangentially), especially if the canker is one of long-standing, since we know that the fungus eventually penetrates the outer rings of wood. Since that is true, the canker might enlarge later on from this same source of infection. Further it may also be possible for spores or bits of mycelium to be transported upward in the sap stream and cause new infections higher up in the tree. A thorough painting of the cut surfaces should go far toward remedying this situation.
