Cape Cod by Henry David Thoreau (find a book to read txt) 📕

in the night, in July, 1855. It moved the sand on the beach opposite the light-house to the depth of six feet, and three rods in width as far as we could see north and south, and carried it bodily off no one knows exactly where, laying bare in one place a large rock five feet high which was invisible before, and narrowing the beach to that extent. There is usually, as I have said, no bathing on the back-side of the Cape, on account of the undertow, but when we were there last, the sea had, three months before, cast up a bar near this lighthouse, two miles long and ten rods wide, over which the tide did not flow, leaving a narrow cove, then a quarter of a mile long, between it and the shore, which afforded excellent bathing. This cove had from time to time been closed up as the bar travelled northward, in one instance imprisoning four or five hundred whiting and cod, which died there, and the water as often turned fresh, and finally gave place to sand. This bar, the inhabitants assured us, might be wholly removed, and the water six feet deep there in two or three days.

The light-house keeper said that when the wind blowed strong on to the shore, the waves ate fast into the bank, but when it blowed off they took no sand away; for in the former case the wind heaped up the surface of the water next to the beach, and to preserve its equilibrium a strong undertow immediately set back again into the sea which carried with it the sand and whatever else was in the way, and left the beach hard to walk on; but in the latter case the undertow set on and carried the sand with it, so that it was particularly difficult for shipwrecked men to get to land when the wind blowed on to the shore, but easier when it blowed off. This undertow, meeting the next surface wave on the bar which itself has made, forms part of the dam over which the latter breaks, as over an upright wall. The sea thus plays with the land holding a sand-bar in its mouth awhile before it swallows it, as a cat plays with a mouse; but the fatal gripe is sure to come at last. The sea sends its rapacious east wind to rob the land, but before the former has got far with its prey, the land sends its honest west wind to recover some of its own. But, according to Lieutenant Davis, the forms, extent, and distribution of sand-bars and banks are principally determined, not by winds and waves but by tides.

Our host said that you would be surprised if you were on the beach when the wind blew a hurricane directly on to it, to see that none of the drift-wood came ashore, but all was carried directly northward and parallel with the shore as fast as a man can walk, by the inshore current, which sets strongly in that direction at flood tide. The strongest swimmers also are carried along with it, and never gain an inch toward the beach. Even a large rock has been moved half a mile northward along-the beach. He assured us that the sea was never still on the back-side of the Cape, but ran commonly as high as your head, so that a great part of the time you could not launch a boat there, and even in the calmest weather the waves run six or eight feet up the beach, though then you could get off on a plank. Champlain and Pourtrincourt could not land here in 1606, on account of the swell (la houlle), yet the savages came off to them in a canoe. In the Sieur de la Borde's "Relation des Caraibes," my edition of which was published at Amsterdam in 1711, at page 530 he says:—

"Couroumon a Caraibe, also a star [i.e. a god], makes the great lames á la mer, and overturns canoes. Lames á la mer are the long vagues which are not broken (entrecoupées), and such as one sees come to land all in one piece, from one end of a beach to another, so that, however little wind there may be, a shallop or a canoe could hardly land (aborder terre) without turning over, or being filled with water."

But on the Bay side the water even at its edge is often as smooth and still as in a pond. Commonly there are no boats used along this beach. There was a boat belonging to the Highland Light which the next keeper after he had been there a year had not launched, though he said that there was good fishing just off the shore. Generally the Life Boats cannot be used when needed. When the waves run very high it is impossible to get a boat off, however skilfully you steer it, for it will often be completely covered by the curving edge of the approaching breaker as by an arch, and so filled with water, or it will be lifted up by its bows, turned directly over backwards, and all the contents spilled out. A spar thirty feet long is served in the same way.

I heard of a party who went off fishing back of Wellfleet some years ago, in two boats, in calm weather, who, when they had laden their boats with fish, and approached the land again, found such a swell breaking on it, though there was no wind, that they were afraid to enter it. At first they thought to pull for Provincetown, but night was coming on, and that was many miles distant. Their case seemed a desperate one. As often as they approached the shore and saw the terrible breakers that intervened, they were deterred. In short, they were thoroughly frightened. Finally, having thrown their fish overboard, those in one boat chose a favorable opportunity, and succeeded, by skill and good luck, in reaching the land, but they were unwilling to take the responsibility of telling the others when to come in, and as the other helmsman was inexperienced, their boat was swamped at once, yet all managed to save themselves.

Much smaller waves soon make a boat "nail-sick," as the phrase is. The keeper said that after a long and strong blow there would be three large waves, each successively larger than the last, and then no large ones for some time, and that, when they wished to land in a boat, they came in on the last and largest wave. Sir Thomas Browne (as quoted in Brand's Popular Antiquities, p. 372), on the subject of the tenth wave being "greater or more dangerous than any other," after quoting Ovid,—

"Qui venit hic fluctus, fluctus supereminet omnes
Posterior nono est, undecimo que prior,"—

says, "Which, notwithstanding, is evidently false; nor can it be made out either by observation either upon the shore or the ocean, as we have with diligence explored in both. And surely in vain we expect regularity in the waves of the sea, or in the particular motions thereof, as we may in its general reciprocations, whose causes are constant, and effects therefore correspondent; whereas its fluctuations are but motions subservient, which winds, storms, shores, shelves, and every interjacency, irregulates."

We read that the Clay Pounds, were so called "because vessels have had the misfortune to be pounded against it in gales of wind," which we regard as a doubtful derivation. There are small ponds here, upheld by the clay, which were formerly called the Clay Pits. Perhaps this, or Clay Ponds, is the origin of the name. Water is found in the clay quite near the surface; but we heard of one man who had sunk a well in the sand close by, "till he could see stars at noonday," without finding any. Over this bare Highland the wind has full sweep. Even in July it blows the wings over the heads of the young turkeys, which do not know enough to head against it; and in gales the doors and windows are blown in, and you must hold on to the lighthouse to prevent being blown into the Atlantic. They who merely keep out on the beach in a storm in the winter are sometimes rewarded by the Humane Society. If you would feel the full force of a tempest, take up your residence on the top of Mount Washington, or at the Highland Light, in Truro.

It was said in 1794 that more vessels were cast away on the east shore of Truro than anywhere in Barnstable County. Notwithstanding that this light-house has since been erected, after almost every storm we read of one or more vessels wrecked here, and sometimes more than a dozen wrecks are visible from this point at one time. The inhabitants hear the crash of vessels going to pieces as they sit round their hearths, and they commonly date from some memorable shipwreck. If the history of this beach could be written from beginning to end, it would be a thrilling page in the history of commerce.

Truro was settled in the year 1700 as Dangerfield. This was a very appropriate name, for I afterward read on a monument in the graveyard, near Pamet River, the following inscription:—
