1) The propagation of chestnut trees by layering which has been reported to be difficult, was tried; then the percentage of rooting, the number and the length of roots developed were investigated.Ordinarily two or four trees of nursery were obtained from one mother tree, and the percentage of rooting showed 45%.The mean of the numbers of roots developed per one nurssery tree was 4.3and the meen of their length was 13.4 c.m. long.2) It is assumed that the success by mean of this treament was due to the applicatication of the "Yokofuse method" in layering which has been often used to the propagation of mulberry trees, and to the volcano ashes' soil in Koma.3) As it were treated with some impetus of the part of the branches on which roots are developed, the percentage of rooting should be more promoted.4) Although this experiment is not enough to give such conclusion, but it may be said that from the results of this experiment, the propagation of chestnut trees by layering is not so difficult as they make out.
