The source of the elements which compose the Pampean alluvia is very uncertain.
It was only in the extra-glacial tracts that alluvia of interglacial age were at all likely to be preserved in any abundance.
Hence, I believe that some of our so-called “post-glacial” alluvia will eventually be assigned to an interglacial horizon.
Then comes the Negro down in the alluvia, with dark skin, woolly hair, and prognathous development.
We see clearly the alluvia of two streams converging from right and left, and uniting to pass to the sea through Brading Harbour.
