In Sekigane Hot-Springs, the chloride and sulfate content and water temperatures of well waters and the amounts of chloride and sulfate fixed to the soil were determined with the samples collected from the various parts of the thermal spring district and its neighbourhood. The chloride and sulfate content of the well water samples collected from the thermal spring district were higher than those from its neighbourhood, and no difference was found for the water temperatures. The amonnts of chloride fixed to the soil in the samples collected from the thermal spring district were greater than those from its neighbourhood, and the amounts of sulfate in the samples collected from the thermal spring district were extremely greater than those from its neighhourhood. As the existence of other sources which would supply the chloride and sulfate to the water and soil is not expected, the difference in the chloride and sulfate content and water temperatures, between the sa.mples from the thermal spring district and its neighbourhood, seems to be due to the effects of thermal springs.
