A few days after this furious gale, we found ourselves in warm weather, having entered the edge of the Gulf Stream. We proceeded in a south-east direction, crossing the trade winds on our way to the equinoctial line. Were it not for the monotony, which always fatigues, there would be few undertakings more interesting than a sail through the latitudes of "the trades," where we meet with a balmy atmosphere, gentle breezes, and smooth seas. In the night the heavens are often unclouded, the constellations seem more interesting, the stars shine with a milder radiance, and the moon gives a purer light, than in a more northern region. Often in my passage through the tropics, during the night-watches, seated on a spare topmast, or the windlass, or the heel of the bowsprit, I have, for hours at a time, indulged my taste for reading and study by the light of the moon. Fish of many kinds are met with in those seas; and the attempt to capture them furnishes a pleasant excitement; and if the attempt is successful, an agreeable variety is added to the ordinary fare on shipboard. The dolphin is the fish most frequently seen, and is the most easily caught of these finny visitors. He is one of the most beautiful of the inhabitants of the deep, and presents a singularly striking and captivating appearance, as, clad in gorgeous array, he moves gracefully through the water. He usually swims near the surface, and when in pursuit of a flying-fish shoots along with inconceivable velocity. The dolphin, when properly cooked, although rather dry, is nevertheless excellent eating; and as good fish is a welcome commodity at sea, the capture of a dolphin is not only an exciting but an important event. When the word is given forth that "there's a dolphin alongside," the whole ship's company are on the alert. Business, unless of the last importance, is suspended, and the implements required for the death or captivity of the unsuspecting stranger are eagerly sought for. The men look resolved, ready to render any assistance, and watch the proceedings with an eager eye; and the wonted grin on the features of the delighted cook, in anticipation of an opportunity to display his culinary skill, assumes a broader character. The captain or the mate takes his station in some convenient part of the vessel, on the bow or on the quarter, or beneath the bowsprit on the martingale stay. By throwing overboard a bright spoon, or a tin vessel, to which a line is attached, and towing it on the top of the water, the dolphin, attracted by its glittering appearance, and instigated by curiosity, moves quickly towards the deceiving object, unconscious that his artful enemy, man, armed with a deadly weapon, a sort of five-pronged harpoon, called a GRANES, is standing over him, with uplifted arm, ready to give the fatal blow.
