“Port a little, you may, my son,” said the master to the man at the helm; “steady, so, keep her. East-and-by-north is the course,” pronouncing the north with a strong emphasis on the O, and without the R—as if it were spelt Nothe. “Just get a gentle pull on our weather-braces, Mr Timmins,” to the mate. “The wind’s drawing a little more aft again. We’re making her walk along, sir,” to the colonel. “She’s not going less than six knots an hour, I’ll warrant, which, with this light wind, is not bad for a craft of her build—she’s no clipper, I own, sir. Heave the log here. I dare say you’ll like to be certain, miss,” turning to Ada, as he thought the operation would amuse her.
The second mate and two hands came aft with the log-line and reel. Bowse took a half-minute glass from the binnacle, and watching till all the sand had run into one end, held it up before him. The seamen, meantime, held the reel up before him, so as to allow it to turn easily in his hands, and the mate, taking the little triangular bit of wood, called the log-ship, adjusted the peg, and drew off, with a peculiar jerk of his left hand, several coils of the stray-line, which he held for a moment over the quarter of the vessel, till he saw that his chief was ready with the glass, and he then hove it over into the water. The first part of the line is called the stray-line, and its object is to allow the log-ship to settle properly in the water, as well as to take it clear of the eddy. As soon as this part had run out, a cloth mark ran through the mate’s fingers. “Turn,” he exclaimed. “Turn,” repeated the master, and turned the glass. The marks rapidly passed through the mate’s hand, as he jerked the line of the reel, always keeping it at a stretch.
“Stop,” sung out Bowse, as the sand had run out of the upper end of the glass.
“Done,” said the mate, and stopped the line.
He had not to count the knots run off, for his experienced eye was able to tell the number by the mark on the line. It must be understood that this line is divided into a certain number of equal parts, each of which bears the same proportion to a mile, which thirty seconds do to an hour, and therefore, as the log-ship remains stationary in the water, according to the number of these proportions dragged through, while the sand is running, so is shown how many miles or knots the vessel is going through the water.
“Six and a quarter,” exclaimed the mate. “That’s what I call good going for a ship with a full cargo, in a breeze like this.”
“That’s what we call heaving the log, Miss Garden,” said the master, who had been explaining the use of the log, though in not quite so succinct a way as I have attempted to do. “You’ll be able to turn the glass another time, I’m sure.”
The glass runs, in reality, only for twenty-eight seconds, as two are considered to be employed in turning it.
Ada, who enjoyed an advantage over the reader, by having the operation performed before her eyes, answered that she clearly understood it, and would always, in future, hold the glass.
“By this calculation, you see, miss, as it is just two hours since we passed Fort Saint Elmo, we have run exactly twelve knots and a half off the reel; though we didn’t go through the water so fast at first, as we are now doing. However, by the look of the land, I calculate we are not much less than that off it. You see we call miles—knots, miss, on account of the knots which are marked on the line. When we can just see the last of some conspicuous point, we shall take its bearing by compass and its distance, and then I shall commence pricking the ship’s course off on the chart, and that is what we call taking our departure. Now you see there’s many people on shore would fancy that when we left the port we took our departure; but the ties which bind a seaman to the shore, and to those we leave behind, are not so quickly parted as they may think, you see, miss.” And the honest master, chuckling at one of the first attempts at wit and gallantry of which he had ever been guilty, thought the next instant he blushed at his own audacity.
