Darwin made long journeys inland with travelling companions from the locality. He spent much of the time away from the ship, returning by prearrangement when "Beagle" returned to ports where mail could be received, and Darwin's notes, journals, and collections sent back to England. He had ensured that his collections were his own and they were shipped back to Henslow in Cambridge to await his return. Several others on board, including FitzRoy and other officers, were able amateur naturalists, and they gave Darwin generous assistance as well as making collections for the Crown, which the Admiralty placed in the British Museum.
