II.第二年度現場調査

抄録

The results of the supplementary survey in the field are described in this paper as the continuation of the former report. The chief object of this work is to determine the vertical distribution of the water content of soil in the frozen zone as well as in the layers under the freeing line. The results are shown in the Figures. As a rule the frozen layer contains excessive water than the soil saturated with water, and a dry layer is always found just below the freezing line, the soil further below being less descicated.
The water content was measured for many samples of frozen soil which show various modes of segregation of ice. The photographs of samples and the amounts of water content were tabulated.
