a large iceberg, often mistaken for a ship.
- 1852  Many of them [icebergs] were of a very dirty colour, from accumulations of mud, gravel, and larger fragments of rock which had taken place in them in the glaciers, and not infrequently very dark seams (the closed up crevasses) could be seen traversing them throughout their whole extent, causing the most illusory and fantastic appearances. These the whalers sometimes mistake for ships, and then they call them "country ships."
