The author describes several examples of the colonization processes in Hokkaido, and the conclusion derived from his research is as follows; the management of rice-farming in newly colonized Hokkaidl mainly depends on the improvement of new varieties of rice and technical progress of cultivation. The development of dairy-farming depends on rail way-transportation and urburn demand for its products. The farmers who are engaged in dairyfarming consume themselves very little milk, meat and butter, eating considerable amount of rice for diet. This is the very point that the dairy farming in Hokkaido is ecologically different from that of European type. The ecological situations of rice- and dairy-farming in Hokkaido are not so well harmonized with natural. conditions of Hokkaido, as they are in the other parts of Japan.
