1) For purpose of determining the relation between felling season of bamboo and its decay, the writer made the following experiment : Test pieces of 3 species of bamboo, Phyllostachys reticulata, P. pubescens, P. nigra var. Henonis, cut down on the definite day of every month, were used as the materials. These test pieces were inoculated with the mycelia of Poria vaporaria and Schizophyllum commune and kept for a hundred days.2) Considering the decrease in weight of test pieces after the decay experiment, P. reticulata was the most durable and P. pubescens and P. nigra var. Henonis followed. In percentage of loss in weight the former showed an average of about 52% of the latter in case of P. vaporaria, and about 72% and in case of S. commune.3) Every bamboo species showed the minimum of decay between September and February of next year.4) From the result shown above, from autumn to winter seems to be the most suitable season for felling of bamboo.
