The drydock 

Bone, Muirhead, Sir, 1876-1953 · 1899

On the left the hull of a big ship, shored up by beams which reach right across the plate and rest on steps descending to the level of the floor of the dock. Farther back, a small steamer with the name Calston, London, on her stern. Beyond the dock and on a higher level is a chimney crossed by a double board inscribed Docking, Painting & Repairing. R. Napier & Sons, Shipbuilders & Engineers. The tall hull is now shaded vertically, as well as horizontally, all over. The inscription which appeared upon it in states II.-V. is worked over and hidden. The steps in the foreground on the right are continued beyond the beam to the foot of the plate.
