ten o'clock
`` I do n't know that there is anything more to be seen . I seemed to know the city before I had seen it . '' `` Very well , then we will go to sea to-night . '' By ten o'clock the ships were under way ; and in a couple of hours more they were in the China Sea , headed north-west-by-north , for Hong-Kong . The sea was as smooth as glass , for the east monsoon seemed to be interrupted under the lee of the islands . The passengers retired at an early hour , and there was no excuse for not going to sleep at once . In the morning the ship was a long way out of sight of land .
