I'm not sure whether anyone is still following this but there are problems with the suggested answer to clue 33. Although it includes small hamlets my gazetteer doesn't index Highwater - where is it? In fact it doesn't bring up anything beginning with words associated with the moon or the tides. Also, spring tides occur at both full moon and new moon so the order of wane and wax would be irrelevant. Any further thoughts would be welcome but meantime it's back to the drawing board!
