A view of the right side of a riveted steel water tank on wooden sleepers on the quayside at Parkeston, Harwich. The box has been fitted over the hole (seen in N22638) using clamps attached onto a vertical bar on the tank. The hole in the box is much larger than that depicted in N22636, suggesting a modification to the design.

Aurora's log records leak stopping parties under instruction in the late morning of 6, 11, 13, and 14 October 1916 [Ship's log, TNA, ADM 53/34496].

The original caption described this as 'Mr Roger's Tank', although the identity of Mr Rogers is unknown.

This part of a series (N22636-N22340) showing the same tank with two methods of fixing similar boxes to the tank sides. The purpose of this tank is not known but it seems to be illustrating a way of reducing water ingress resulting from a shell hole in the side of a ship. The box is fitted over the hole and the water can continue to pour in through the hole in the box. Once the box is securely fitted the valve operating the hole in the box can be closed. This should reduce the water entering the ship.
