P.S. Well, anyway, I've cured the chronometer. After knocking about the sea for eight squally, rainy days, most of the time hove to, I succeeded in catching a partial observation of the sun at midday. From this I worked up my latitude, then headed by log to the latitude of Lord Howe, and ran both that latitude and the island down together. Here I tested the chronometer by longitude sights and found it something like three minutes out. Since each minute is equivalent to fifteen miles, the total error can be appreciated. By repeated observations at Lord Howe I rated the chronometer, finding it to have a daily losing error of seven-tenths of a second. Now it happens that a year ago, when we sailed from Hawaii, that selfsame chronometer had that selfsame losing error of seven-tenths of a second. Since that error was faithfully added every day, and since that error, as proved by my observations at Lord Howe, has not changed, then what under the sun made that chronometer all of a sudden accelerate and catch up with itself three minutes? Can such things be? Expert watchmakers say no; but I say that they have never done any expert watch-making and watch-rating in the Solomons. That it is the climate is my only diagnosis. At any rate, I have successfully doctored the chronometer, even if I have failed with the lunacy cases and with Martin's yaws.
