Quotation from: The Cruise of the SnarkWritten by: Jack London |
|
This is the illustration. At eight A.M. I took my chronometer sight. At the same moment the distance recorded on the log was noted. At twelve M., when the sight for latitude was taken. I again noted the log, which showed me that since eight o'clock the Snark had run 24 miles. Her true course had been west 0.75 south. I entered Table I, in the distance column, on the page for 0.75 point courses, and stopped at 24, the number of miles run. Opposite, in the next two columns, I found that the Snark had made 3.5 miles of southing or latitude, and that she had made 23.7 miles of westing. To find my eight o'clock' latitude was easy. I had but to subtract 3.5 miles from my noon latitude. All the elements being present, I worked up my longitude.
