"Kirkwall Harbour, Orkney, Headquarters of the Northern Patrol" image: a view of the busy harbour at Kirkwall. In the left foreground there are small boats, perhaps tugs or fishing vessels, moored against the harbour wall, with larger merchant vessels moored further back. The jetty runs down from the centre of the composition. There are many figures walking up and down the jetty, and more ships and boats out at sea in the distance.
