By the 1960s there were only a small number of boats using the London canals for trade and by the 1970s the use of canals for leisure had begun. A large crowd has gathered to watch police divers search the canal; unfortunately Henry Grant hasn't left any notes about this photograph so we dont know why they were in the water or where exactly they were.
