The containers made of bamboos aged two months (I), three months (II), one year (III) and three years (IV) were set in the field, and the biotic community in each of them was investigated ecologically with special reference to the succession of the Protozoa. 1. The appearance of Diptera larvae was characteristic in I-IV and closely related to the occurrence of the Protozoa association. 2. The water situations were similar to each other in the fauna of Protozoa and differed in the velocities of their succession ; namely, in I, it changed rapidly, in II, following I, and in IV, changed most slowly. 3. The characteristics of the velocity of succession was explained by taking the progressive changes of the amount of matter into consideration. 4. When the bottles containing the bamboo juices with different concentration were placed in the field, they were characterized by a definite seral stage of the protozoan succession after bacterial contamination.
