July 10th.–A fishing excursion, last Saturday afternoon, eight or ten miles out in the harbor. A fine wind out, which died away towards evening, and finally became quite calm. We cooked our fish on a rock named “Satan,” about forty feet long and twenty broad, irregular in its shape, and of uneven surface, with pools of water here and there, left by the tide,–dark brown rock, or whitish; there was the excrement of sea-fowl scattered on it, and a few feathers. The water was deep around the rock, and swelling up and downward, waving the seaweed. We built two fires, which, as the dusk deepened, cast a red gleam over the rock and the waves, and made the sea, on the side away from the sunset, look dismal; but by and by up came the moon, red as a house afire, and, as it rose, it grew silvery bright, and threw a line of silver across the calm sea. Beneath the moon and the horizon, the commencement of its track of brightness, there was a cone of blackness, or of very black blue. It was after nine before we finished our supper, which we ate by firelight and moonshine, and then went aboard our decked boat again,–no safe achievement in our ticklish little dory. To those remaining in the boat, we had looked very picturesque around our fires, and on the rock above them,–our statues being apparently increased to the size of the sons of Anak. The tide, now coming up, gradually dashed over the fires we had left, and so the rock again became a desert. The wind had now entirely died away, leaving the sea smooth as glass, except a quiet swell, and we could only float along, as the tide bore us, almost imperceptibly. It was as beautiful a night as ever shone,–calm, warm, bright, the moon being at full. On one side of us was Marblehead light-house, on the other, Baker’s Island; and both, by the influence of the moonlight, had a silvery hue, unlike their ruddy beacon tinge in dark nights. They threw long reflections across the sea, like the moon. There we floated slowly with the tide till about midnight, and then, the tide turning, we fastened our vessel to a pole, which marked a rock, so as to prevent being carried back by the reflux. Some of the passengers turned in below; some stretched themselves on deck; some walked about, smoking cigars. I kept the deck all night. Once there was a little cat’s-paw of a breeze, whereupon we untied ourselves from the pole; but it almost immediately died away, and we were compelled to make fast again. At about two o’clock, up rose the morning-star, a round, red, fiery ball, very comparable to the moon at its rising, and, getting upward, it shone marvelously bright, and threw its long reflection into the sea, like the moon and the two light-houses. It was Venus, and the brightest star I ever beheld; it was in the northeast. The moon made but a very small circuit in the sky, though it shone all night. The aurora borealis shot upwards to the zenith, and between two and three o’clock the first streak of dawn appeared, stretching far along the edge of the eastern horizon,–a faint streak of light; then it gradually broadened and deepened, and became a rich saffron tint, with violet above, and then an ethereal and transparent blue. The saffron became intermixed with splendor, kindling and kindling, Baker’s Island lights being in the centre of the brightness, so that they were extinguished by it, or at least grew invisible. On the other side of the boat, the Marblehead light-house still threw out its silvery gleam, and the moon shone brightly too; and its light looked very singularly, mingling with the growing daylight. It was not like the moonshine, brightening as the evening twilight deepens; for now it threw its radiance over the landscape, the green and other tints of which were displayed by the daylight, whereas at evening all those tints are obscured. It looked like a milder sunshine,–a dreamy sunshine,–the sunshine of a world not quite so real and material as this. All night we had heard the Marblehead clocks telling the hour. Anon, up came the sun, without any bustle, but quietly, his antecedent splendors having gilded the sea for some time before. It had been cold towards morning, but now grew warm, and gradually burning hot in the sun. A breeze sprang up, but our first use of it was to get aground on Coney Island about five o’clock, where we lay till nine or thereabout, and then floated slowly up to the wharf. The roar of distant surf, the rolling of porpoises, the passing of shoals of fish, a steamboat smoking along at a distance, were the scene on my watch. I fished during the night, and, feeling something on the line, I drew up with great eagerness and vigor. It was two of those broad-leaved sea-weeds, with stems like snakes, both rooted on a stone,–all which came up together. Often these sea-weeds root themselves on mussels. In the morning, our pilot killed a flounder with the boat-hook, the poor fish thinking himself secure on the bottom.
