All places surveyed are included in the zone of serpentin. Almost all hills are slided and collapsed and they have no big tree. The reservoir is being filled with a large amount of slided materials. Four places were chosen along the road for the present survey where some special features of the land-slide were respectively observed and resistivities of serpentin could be distinguished from that of the other material. We have had such a conclusion ac that the resistivity method will be useful for the survey of the land-slide in this district.
