eight o'clock in the morning
When it was discovered that this man had long been suspected of being an _ informer _ among the crew , little surprise and less pleasure were evinced at his narrow escape . I can not quit this matter of the hammocks without making mention of a grievance among the sailors that ought to be redressed . In a man-of-war at sea , the sailors have _ watch and watch ; _ that is , through every twenty-four hours , they are on and off duty every four hours . Now , the hammocks are piped down from the nettings -LRB- the open space for stowing them , running round the top of the bulwarks -RRB- a little after sunset , and piped up again when the forenoon watch is called , at eight o'clock in the morning ; so that during the daytime they are inaccessible as pallets . This would be all well enough , did the sailors have a complete night 's rest ; but every other night at sea , one watch have only four hours in their hammocks . Indeed , deducting the time allowed for the other watch to turn out ; for yourself to arrange your hammock , get into it , and fairly get asleep ; it maybe said that , every other night , you have but three hours ' sleep in your hammock . Having then been on deck for twice four hours , at eight o'clock in the morning your _ watch-below _ comes round , and you are not liable to duty until noon .
