Master and Commander (Aubrey & Maturin, #1)

by Patrick O'Brian

Hitherto, Jack had been too busy working up his crew to pay much attention to the education of his midshipmen, but he had looked at yesterday’s slips and they, with a very suspicious unanimity, had shown the Sophie in 39°21'N., which was fair enough, but also in a longitude that she could only have reached by cleaving the mountain-range behind Valencia to a depth of thirty-seven miles. ‘What do you mean by sending me this nonsense?’ he asked them. It was not really an answerable question; nor were many of the others that he propounded, and they did not, in fact, attempt to answer them; but they agreed that they were not there to amuse themselves, nor for their manly beauty, but rather to learn their professions; that their journals (which they fetched) were neither accurate, full, nor up to date, and that the ship’s cat would have written them better; that they would for the future pay the greatest attention to Mr Marshall’s observation and reckoning; that they would prick the chart daily with him; and that no man was fit to pass for a lieutenant, let alone bear any command (‘May God forgive me,’ said Jack, in an internal aside) who could not instantly tell the position of his ship to within a minute – nay, to within thirty seconds.
