six o'clock
Sirhassen was forty sea miles from Cape Datu , or five hours as the yacht was running ; and when land was reported on the beam , bearing about west , he knew what it was . The chart gave the island as one of considerable size compared with the multitude of small ones in that locality ; and this indication afforded him a further clew to the identification . At eight bells , or four o'clock , the morning watch came on duty , with Achang as its officer . Captain Scott did not turn out when the second mate was called , with Felix to take his place at the engine , and it was six o'clock when he made his appearance . Except when there is only one mate , as in small vessels , the captain keeps no watch ; but he is liable to be called at any hour of the night in case of a squall or other peril . His responsibility may induce him to spend the entire night on deck . When he came out of the cabin , his first care was to observe the signs which indicate the coming weather .
