In Fukudome, Kitadani Village, the chloride, sulfate and phosfate content and water temperatures of well waters and the amounts of chloride and sulhte fixed to the soil were determined with the samples collected from various parts near the spring which contains much
inorganic salts. The chloride, sulfate and phosfate content of the well water samples collected from the district which surrounds the spring, were higher than those from its neighhonrhood, but for the water temperatures of the well water samples, no difference was recognized. As the existence of other sources which would supply the chloride, sulthte and phosfate to the well water is not expected, the difference in the chloride, sulfate and phosfate content of well waters between the samples collected from the A district and its neighbourhood, seems to be due to the effects of the spring which contains much inorganic salts or its sources.
