The lock gate

An original fiction passage set in the nineteenth century.

The barge waited below while Jacob fitted the iron handle into the lock mechanism. He had watched his father perform the task a hundred times, yet the long oak beam seemed to have grown heavier now that it belonged in his hands. Water pressed, dark and impatient, against the gates. He set his shoulder to the beam, but stopped when the mechanism gave a sudden groan. The boatman said nothing; his silence was worse than advice.

A floating twig turned slowly towards the narrow opening, and Jacob understood the pull of the water. “Not yet,” he called as the boatman reached for a rope. He raised the paddle by inches. The water climbed smoothly against the brickwork, while the groan beneath his palm settled into a steady click. When the two levels met, Jacob walked the full length of the beam without pausing. The gate swung open before the barge’s bow.
