Part of the preparation was to let the captain know beforehand that it was eight o'clock, and get his authority that it might be so; subject always to the yet higher authority that the yards and sails were ready. If they were not, so much the worse for eight o'clock. It had to wait quite as imperatively as the sun did for Joshua. Sunset, when the masts and yards came down, was equally under bonds; it awaited the pleasure of the captain or admiral. Indeed, in my time a story ran of a court-martial at a much earlier day, sitting in a capital case. By law, each day's session must end by sundown. On the occasion in question, sundown was reported to the admiral--or, rather, commodore; we had no admirals then. He sent to know how soon the court could finish. The reply was, in about fifteen minutes. "Tell the officer of the deck not to make it sundown until he hears from me;" and, in defiance of the earth's movement, the colors were kept flying in attestation that the sun was up. One other hour of the twenty-four, noon, was brought in like manner to the captain's attention, and required his action, but it was treated with more deference; recognition rather than authority was meted to it, and it was never known to be tampered with. The circumstance of the sun's crossing the ship's meridian was unique in the day; and the observation of the fact, which drew on deck all the navigating group with their instruments, establishing the latitude immediately and precisely, was of itself a principal institution of the ship's economy. Such claims were not open to trifling; and were there not also certain established customs, almost vested interests, such as the seven-bell nip, cocktail or otherwise, connected with the half-hour before, when "the sun was over the fore-yard"? I admit I never knew whence the latter phrase originated, nor just what it meant, but it has associations. Like sign language, it can be understood.
