"After tacking for three weeks off Gibraltar, wearing out our cordage and exhausting our larder, we put into the bay and anchored. Here we were surrounded by vessels from all parts of the world, and were so near the town that we could almost exchange greetings with those on shore. One Sunday the Spaniards had a bull-fight just across the Neutral Ground; but I preferred a quiet New England Sabbath on shipboard. "After lying at anchor in the bay for two weeks I went on shore one day to lunch with an American lady. Returning to the ship in the evening, I betook myself to my berth. At midnight I heard unusual sounds, clanking of chains, and sailors singing 'Heave ho!' From my port-hole I could see an unusual stir, and dressing in haste went on deck. Sure enough the wind had changed, and all the vessels in the bay were alive with excitement. The captain was radiant. I could see his beaming face, for it was clear and beautiful as moonlight could make it. He invited me to stay on deck, sent for a cup of coffee, and made himself very agreeable. We were soon under way. I was in a kind of ecstasy with the novelty and the beauty of it all. The full moon, the grand scenery, the Pillars of Hercules, solemn in the moonlight, and the added charm of six hundred vessels, from large to small craft, all in full sail, made a rare picture. I sat on deck till morning, and certainly never saw a more beautiful sight than that fleet spreading its wings like a flock of mighty sea-birds, and moving off together from the Mediterranean into the Atlantic." Such picturesque scenes are not so likely to be witnessed now; for since the introduction of steam the plain and prosaic, but very useful, "tug" tows off the wind-bound bark through the dreaded Straits into the open sea, where she can spread her wings and fly across the wide expanse of the ocean. To-day, as we look down from the signal station, we see no gathered ships below waiting for a favoring breeze; the wind scarcely ripples the sea, and the boats glide gently whither they will, while here and there a great steamer from England, bound for Naples, or Malta, or India, appears on the horizon, marking its course by the long line of smoke trailing behind it. To this wonderful combination of land and sea nothing can be added except by the changing light which falls upon it. For the fullest effect you must wait till sunset, when the evening gun has been fired, to signal the departing day, and its heavy boom is dying away in the distance, "Swinging low with sullen roar." Then the sky is aflame where the sun has gone down in the Atlantic; and as the last light from the west streams through the Straits, they shine as if they were the very gates of gold that open into a fairer world than ours.
