o the Chelmer and Blackwater Navigation in Essex, the waterway which took goods between Chelmsford and Heybridge Basin on the River Blackwater.  If you look carefully behind the rushes on the photo on the left, you will see some corrugated iron. This was brought back from the trenches in France after the end of the First World War, and was used to reinforce the sides of the waterway to prevent erosion.  This is the last piece left on the waterway, between Paper Mill Lock and Little Baddow Mill.
