Mild as it was on shore this morning, the wind was cold and piercing on the water. Though it be the hottest day in July on land, and the voyage is to last but four hours, take your thickest clothes with you, for you are about to float over melted icebergs. When I left Boston in the steamboat on the 25th of June the next year, it was a quite warm day on shore. The passengers were dressed in their thinnest clothes, and at first sat under their umbrellas, but when we were fairly out on the Bay, such as had only their coats were suffering with the cold, and sought the shelter of the pilot’s house and the warmth of the chimney. But when we approached the harbor of Provincetown, I was surprised to perceive what an influence that low and narrow strip of sand, only a mile or two in width, had over the temperature of the air for many miles around. We penetrated into a sultry atmosphere where our thin coats were once more in fashion, and found the inhabitants sweltering. Leaving far on one side Manomet Point in Plymouth and the Scituate shore, after being out of sight of land for an hour or two, for it was rather hazy, we neared the Cohasset Rocks again at Minot’s Ledge, and saw the great Tupelo-tree on the edge of Scituate, which lifts its dome, like an umbelliferous plant, high over the surrounding forest, and is conspicuous for many miles over land and water. Here was the new iron light-house, then unfinished, in the shape of an egg-shell painted red, and placed high on iron pillars, like the ovum of a sea monster floating on the waves,—destined to be phosphorescent. As we passed it at half-tide we saw the spray tossed up nearly to the shell. A man was to live in that egg-shell day and night, a mile from the shore. When I passed it the next summer it was finished and two men lived in it, and a light-house keeper said that they told him that in a recent gale it had rocked so as to shake the plates off the table. Think of making your bed thus in the crest of a breaker! To have the waves, like a pack of hungry wolves, eying you always, night and day, and from time to time making a spring at you, almost sure to have you at last. And not one of all those voyagers can come to your relief,—but when your light goes out, it will be a sign that the light of your life has gone out also. What a place to compose a work on breakers! This light-house was the cynosure of all eyes. Every passenger watched it for half an hour at least; yet a colored cook belonging to the boat, whom I had seen come out of his quarters several times to empty his dishes over the side with a flourish, chancing to come out just as we were abreast of this light, and not more than forty rods from it, and were all gazing at it, as he drew back his arm, caught sight of it, and with surprise exclaimed, “What’s that?” He had been employed on this boat for a year, and passed this light every weekday, but as he had never chanced to empty his dishes just at that point, had never seen it before.
