On the whole, it is estimated that the marsh and the sand islands have about an equal aggregate extent. In areas where the sand islands cover less than 25 per cent of the surface the soil on the islands is undifferentiated and the area is mapped with the marsh soil. Where the islands make up more than 75 per cent of the total area the whole tract is mapped as one of the Plainfield types.

The sand islands are usually fairly well drained, while the intervening areas of marsh are naturally poorly drained. A large proportion of this class of land has been incorporated in drainage districts and is now being reclaim'ed by large open ditches or canals. Origin.--The greater portion of the material composing this mixed type is of alluvial origin, having come in part from granitic rocks, but probably more largely from sandstone formations. Varying amounts of organic matter have accumulated in the lower places, which accounts for the dark color.
