The Hope - Pedro and others.
The Hope (or Hope Reach) is shown on the endpaper maps of my "Everybody's Pepys" as being that stretch of the Thames between Tilbury and the mouth of the Medway, at which point the estuary begins. I used to live in Stanford-le-Hope, Essex, which is on a diminutive stream named the Hope. Stream is the word: we used to jump it without getting wet. It enters the Thames about two miles south of Stanford and three miles east of Tilbury.
