In this paper, the writer investigated on the relation between the tendency of the distribution of acidities and the morphological characteristics of the profiles in "Hiba" forest regions of the Tsugaru and the Shimokita Peninsulas, and he found that the distribution of acidities have close relation with both morphological characteristics and soil formation process, because they are characterized by the leaching of base and the movement of colloidal complex.The soil of "Hiba" forest regions are divided into the four main classes according to the distribution of acidities, as follows;(1) Reddish-Brown Forest Soil.(2) Leached Brown Forest Soil.(3) Podzolized Soil.(4) Ground-Water Soil and Wet Brown Forest Soil.To conclude, the writer wishes to express his sincere thanks to the superiors of the Aomori Regional Forestry Office, Dr. M. OHMASA, Head of the Government Forest Experiment Station and Dr. T. SHIBAMOTO, Professor of the Tokyo University, for their sympathetic attitude and continual instruction; to Mr. K. YAMADA, assistant in my laboratory, for his kind assistance.
