I just read an interesting Reuters article on Yahoo News by Stefano Ambrogi. It is about a man who searches through the Thames mud during low tide and finds items from centuries past which are preserved because of a lack of oxygen in the mud. It's a very interesting read for those who are interested in old Britain. The mud digging reminds me of the fact that poor men, women and children, in the past, used to dig in the mud of the once filthy sewer called the Thames to find items to sell to survive. Sad, but true.
