Rusty Water

When I walked down to the studio, I saw the brook was really full.  I cross it twice on my way; once by a footbridge, once a road bridge.  There was so much water rushing down from the hills that there was white water.  Well, they would have been if the water wasn't brown.  The water in the brook is so brown even the white bits are brown.  That is because the water is - today's word - chalybeate.  That is full of iron.  It doesn't make for a very attractive brook, as it is always a kind of rusty colour.
