I dutifully answered; and, moving aft to the skylight, raised the canvas cover which had been placed over it to mask the light of the low-turned lamp which was kept burning all night in the fore cabin, and glanced at the clock which, screwed to the coaming on one side of the tell-tale compass, balanced the barometer which, hung in gimbals, was suspended on the other side.  The clock marked the time as two minutes to five a.m., or within two minutes of two bells in the morning watch.
