I woke up this morning thinking about the fractions of Iron Pyrites that are found on the coast. I remember the story I once was told about Iron - falling down from heaven, meteor showers they are called. The Iron then flows in the water system just the same way it does in our blood, until it comes to a rest in a lake or a shore.
The Iron ore I have found was beached together with flint nodules and salted by the sea. Once upon a time people used to strike the two minerals together to produce a spark for their fire. So many journeys are met thus. Such a junction of stories is the sea.
