Passing Yarmouth and Harwich, the railway turns northward at the elbow of the cape, where Chatham is on the ocean shore. Brewster is northward, and Eastham, noted for its fortified church, whose colonial pastor received by law, for his salary, part of every stranded whale coming upon the shore. To the left is Welfleet, on the bay shore, and to the right the triple lighthouses of Nauset Beach, in front of which the ocean tides divide, moving in opposite directions, one current south to Nantucket Sound, and the other north, to go around the Cape into Massachusetts Bay. Northward is the sandy desert of Truro, the "Dangerfield" of early days, regarded as the most fatal coast in New England. This town of Truro has been described as "a village where its able-bodied men are all ploughing the ocean together as a common field," while in North Truro "the women and girls may sit at their doors and see where their husbands and brothers are harvesting their mackerel fifteen to twenty miles off on the sea, with hundreds of white harvest-wagons." Here, upon the high hill making the ocean shore, where the headland curves from north around to the west, is the guardian beacon of Cape Cod, the lofty Highland Light, forty-one miles southeast of Boston Light, and whose powerful white rays shine for twenty miles over the ocean without, and the bay within. The tower stands on a hill one hundred and forty-two feet high, and the light is elevated nearly two hundred feet. Along here Thoreau walked on the "sand-bar in the midst of the sea," and as he gazed far over the ocean, thus reflected: "The nearest beach to us on the east was on the coast of Galicia in Spain, whose capital is Santiago, though by old poets' reckoning it should have been Atlantis, or the Hesperides; but Heaven is found to be farther west now. At first we were abreast of that part of Portugal _entre Douro e Mino_, and then Galicia and the port of Pontevedro opened to us as we walked along, but we did not enter, the breakers ran so high. The bold headland of Cape Finisterre, a little north of east, jutted toward us next with its vain brag; for we flung back 'Here is Cape Cod, Cape Land's Beginning.' A little indentation toward the north--for the land loomed to our imaginations like a common mirage--we knew was the Bay of Biscay, and we sang, 'There we lay, till next day, in the Bay of Biscay, O!' A little south of east was Palos, where Columbus weighed anchor, and further yet the pillars which Hercules set up." THE PURITAN COMPACT.
