We find ourselves in the valley of the Drave, in one of those boundless tracts where even the wild beasts lose themselves. Here are primeval forests, the roots of which rest in the water of a great swamp encircled not by water lilies and reed-grass, but by giant trees whose branches, dropping below the surface, form new roots in the quickening water. Here the swan builds its nest; this is the haunt of the heron and all those wild creatures one of which only now and then marches out into more frequented regions. On the higher ground, where in late summer the waters ebb, spring such flowers as might have been seen just after the deluge, so luxuriant and so strange is their mighty growth out of the slimy mud.
