Historical Context
As the gatekeeper is preparing to close the downstream lock gates, another person is tying the ropes to the bollards.  After the downstream gates are closed, the underwater sluices are opened, and the large valves allow water from the canal above the lock to flow through and fill the lock.  The packet boat begins to rise as the level of water also rises.  When the water has risen to the level in the canal above, the upstream gates are opened, the ropes are reattached to the team of mules, and the packet boat continues on its journey.
