    — The pH in water of the hillside soils varied between 3.1 and 6.1 with a mean of 4.2. The pattern of pH variation is complex and does not clearly relate either to cultivation or occupation. The most consistent, though weak, correlation appears to be between higher pH and flushes or bogs, which indicates that the local groundwaters are comparatively basic.
