There was a log-reel and line on deck, and I found a sand-glass in the chest in my cabin in which I had met with the quadrants, perspective glass, and the like, and I kept this log regularly going, marking a point of departure on the chart the American captain had given me, which I afterwards found to be within two leagues and a half of the true position.

A latitude by Polaris, and at the same time some star in one of the southern quadrants, as a check, will give admirable results.

It sounded good, and might have worked if there had been the normal food reserve, or if the other three quadrants had been willing to do as much.
