The succession of vegatation was investigated in the intertidal zone at Takamatsu harbor from 1947 to 1955. As an experimental spot the surface of one of the many boulders in the habor was selected. The change of vegetation presented the following two interesting points : At first, there was a closed community of Gloiopeltis furcata on the highest zone of the rock surface, but Ulva pertusa gradually began to grow among it. At last, the rock surface was almost covered with a closed community of Ulva pertusa, but Sargassum Thunbergii was invading them. It is said that this is the influence of alternation of the substratum in the Takamatsu district, which has been caused by the Nankai earthquake of 1946. Perennial algae can not easily emigrate, while the substratum is submerging. On the other hand, if the substratum is stable it can easily emigrate. The zonal arrangements which have been constant for these nine years, can be summarized as follows : [table]
