Due to heavy surf, they only stayed at Fernando de Noronha for a day to make the required observations, and Fitzroy decided to make for Bahia, Brazil, to rate the chronometers and take on water. On 28 February, they reached the continent, arriving at the magnificent sight of the town now known as Salvador, with large ships at harbour scattered across the bay. On the next day, Darwin was in "transports of pleasure" walking by himself in the tropical forest, and in "long naturalizing walks" with others continued to "add raptures to the former raptures". He found the sights of slavery offensive, and when FitzRoy defended the practice by describing a visit to a slaveowner whose slaves replied "no" on being asked by their master if they wished to be freed, Darwin suggested that answers in such circumstances were worthless. Enraged that his word had been questioned, FitzRoy lost his temper and banned Darwin from his company. The officers had nicknamed such outbursts "hot coffee," and within hours FitzRoy apologised, and asked Darwin to remain. Later, FitzRoy had to remain silent when Captain Paget visited them and recounted "facts about slavery so revolting" that refuted his claim.
