About eleven
o'clock
On the whole , the cabin-boy was pretty well satisfied that he had won the money honestly , and he carefully bestowed it with his clothing in his berth . Early in the morning Mr. Watts went on shore with a boat 's crew , to commence bringing off the water casks . It required the whole forenoon to remove the old casks , and stow the new ones in the hold . About eleven o'clock the mate complained of a chilly sensation , and a pain in his back , which was followed up by a severe headache . He was soon compelled to leave his work , and take to his berth in the cabin . The next boat from the shore brought off a surgeon , who promptly pronounced the disease the yellow fever . Before the Roebuck could get off , two of the sailors were attacked by the terrible malady .
