"Friday.--Yesterday was a day of complete success, the paying out in every respect satisfactory. The wind still from the eastward, but inclined to draw to the northward, the sea entirely gone down. As Mr. Canning told us we should see the after tank emptied at eleven o'clock, ship's time, we were all collected there about ten o'clock, by which time the cable was down to the last flake. Next to having daylight for changing from the after to the fore tank, we could not have had a more favorable time--clear starlight, no wind, and a smooth sea. Looking down into the tank, the scene was highly picturesque. The cable-watch, whose figures were lighted up by the lamps suspended from above, slowly and cautiously lifted the turns of the coil to ease their path to the eye. As each found its way to the drum, the wooden floor of the tank showed itself, and then we saw more floor, and as its area increased the cable swept along its surface with a low, subdued noise, until, with a graceful curve, it mounted to the outlet, where it was soon to join a fresh supply; and now we hear the word passed that they have arrived at the last turn, and the men who stood on the stages of the platform of the eye with the bight, watch the arrival of the cable and pass it up with tender caution, until it reaches the summit; then it rushes down a wooden incline to meet the spliced rope, which had by this time come down along the trough leading from the forward tank. This operation was conducted with great skill by Mr. Canning and his experienced assistants, Messrs. Clifford and Temple. At eleven minutes past one A.M. (Greenwich time), the fresh rope was going over the stern, and the screw engines going ahead at thirteen minutes past one. A watch of four men is now stationed, fore and aft, all along the trough, which is illuminated by many lamps at short distances from each other. A lamp with a green light indicates the mile-mark as it comes up from the tank, and this signal is repeated until it reaches the stern, where it is recorded by the clerk who keeps the cable-log, in an office adjoining the paying-out machinery. A red lamp indicates danger. During the daytime red and blue flags are used. All through the night the sea was smooth as glass, and by this morning we saw that a sensible impression had been made on the contents of the fore tank. The ship begins to lighten at the bows, and by this time to-morrow will come up more as the cable passes out of the tank.
