The New International Encyclopædia…
“ The soils of Maine, with the exception of the Pleistocene marine clays along the coast, are almost wholly glacial. Along some of the rivers and lakes and in many old lake bottoms, long since filled up or drained out, there are alluvial plains of great fertility. The higher outcrops of the crystalline old land are largely denuded of all soil, while the whole surface of the State is more or less strewn with glacial débris. The drift is in places arable, though in wide areas it is unsuited for agriculture. ”
