"Beagle laid ashore, River Santa Cruz", copperplate engraving by Thomas Landseer, art by Conrad Martens, from "The Narrative of the Surveying Voyages of HMS Adventure and Beagle", published by Henry Colburn in 1838. The Beagle was grounded for repairs on the April 16, 1834 to repair damage caused by a rock at Port Desire and to check that the copper sheets were intact; Fitzroy notes they were about to enter the Pacific where worms soon eat their way through unprotected planks. They found that a piece of the false keel had been knocked off and the copper was heavily rubbed in places. The carpenter, Mr. May, repaired it all in one tide. The Beagle undertook a repainting and refit while Fitzroy, Darwin and a small crew explored upriver for several days.
