The _Bessy_--for so Ben Tripper had named his bawley, after his favourite sister--was lying on the mud just above Leigh. A fishy smell pervaded the air, for close by were the boiling-sheds, with their vast heaps of white cockle-shells. These were dug by the cocklers either from the sand at the end of the Canvey Island or on the Maplin Sands somewhere off Shoebury.
