Chemical and mineralogical studies were made of the Wethersfield silt loam, a Brown Podzolic soil derived principally from sandstone, siltstone and shale. The clay minerals identified were illite, vermiculite, chlorite, and interstratified montmorillonitechlorite. Illite decreased from the parent material (70%) to the surface (35%) while vermiculite increased from 5% in the parent material to 40% in the surface. The interstratified montmorillonite‐chlorite was positively identified in the B 3 and C horizons and composed 15% of the clay fraction. The chlorite, hematite, quartz and feldspars were present in quantities ranging from 5–10% each. Field observations of a compact C horizon capable of supporting a perched water table and a 7% slope facilitating lateral movement of water help to explain the results of the mechanical, chemical, and mineralogical analyses performed in the laboratory.
