These image are from the archive and show the lock keeper on the Rochdale Canal in the centre of Manchester in the Spring of 1977. Those gnarled, strong hands look as though they have endured a lifetime on the cut (Travel Theme: Strong & Weekly Photo Challenge: Endurance).
In those days the Rochdale was still in private ownership and you were obliged to pay for the descent along the short stretch of canal which links the Ashton Canal with the Bridgewater at Castlefield. There was so much water flowing down the Rochdale that it cascaded over the back gates and made the process of emptying the lock a long, slow process. When I passed this way again in 2008 the lock keeper and the house adjacent to the top lock were gone but, the plumbing remained a problem.
