Arriving at Mauritius on 29 April 1836, Darwin was impressed by the civilised prosperity of the French colony, which had come under British rule. He toured the island, examining its volcanic mountains and fringing coral reefs. The Surveyor-general Captain Lloyd took him on the only elephant on the island to see an elevated coral plain. By then, FitzRoy was writing the official "Narrative" of the "Beagle" voyages, and after reading Darwin’s diary he proposed incorporating it into the account, a suggestion Darwin discussed with his family.
