Periwinkles (?) (Fusus decemcostatus).
We afterward saw some other kinds on the Bay-side. Gould states that this Cape “has hitherto proved a barrier to the migrations of many species of Mollusca.”—“Of the one hundred and ninety-seven species [which he described in 1840 as belonging to Massachusetts], eighty-three do not pass to the South shore, and fifty are not found on the North shore of the Cape.”
Among Crustacea, there were the shells of Crabs and Lobsters, often bleached quite white high up the beach; Sea or Beach Fleas (Amphipoda); and the cases of the Horse-shoe Crab, or Saucepan Fish (Limulus Polyphemus), of which we saw many alive on the Bay side, where they feed pigs on them. Their tails were used as arrow-heads by the Indians.
Of Radiata, there were the Sea Chestnut or Egg (Echinus granulatus), commonly divested of its spines; flat circular shells (Scutella parma?) covered with chocolate-colored spines, but becoming smooth and white, with five petal-like figures; a few Star-fishes or Five-fingers (Asterias rubens); and Sun-fishes or Sea-jellies (Aureliæ).
There was also at least one species of Sponge.
The plants which I noticed here and there on the pure sandy shelf, between the ordinary high-water mark and the foot of the bank, were Sea Rocket (Cakile Americana), Saltwort (Salsola kali), Sea Sandwort (Honkenya peploides), Sea Burdock (Xanthium echinatum), Sea-side Spurge (Euphorbia poylgonifolia); also, Beach Grass (Arundo, Psamma, or Calamagrostis arenaria), Sea-side Golden-rod (Solidago sempervirens), and the Beach Pea (Lathyrus maritimus).
Sometimes we helped a wrecker turn over a larger log than usual, or we amused ourselves with rolling stones down the bank, but we rarely could make one reach the water, the beach was so soft and wide; or we bathed in some shallow within a bar, where the sea covered us with sand at every flux, though it was quite cold and windy. The ocean there is commonly but a tantalizing prospect in hot weather, for with all that water before you, there is, as we were afterward told, no bathing on the Atlantic side, on account of the undertow and the rumor of sharks. At the lighthouse both in Eastham and Truro, the only houses quite on the shore, they declared, the next year, that they would not bathe there “for any sum,” for they sometimes saw the sharks tossed up and quiver for a moment on the sand. Others laughed at these stories, but perhaps they could afford to because they never bathed anywhere. One old wrecker told us that he killed a regular man-eating shark fourteen feet long, and hauled him out with his oxen, where we had bathed; and another, that his father caught a smaller one of the same kind that was stranded there, by standing him up on his snout so that the waves could not take him. They will tell you tough stories of sharks all over the Cape, which I do not presume to doubt utterly,—how they will sometimes upset a boat, or tear it in pieces, to get at the man in it. I can easily believe in the undertow, but I have no doubt that one shark in a dozen years is enough to keep up the reputation of a beach a hundred miles long. I should add, however, that in July we walked on the bank here a quarter of a mile parallel with a fish about six feet in length, possibly a shark, which was prowling slowly along within two rods of the shore. It was of a pale brown color, singularly film-like and indistinct in the water, as if all nature abetted this child of ocean, and showed many darker transverse bars or rings whenever it came to the surface. It is well known that different fishes even of the same species are colored by the water they inhabit. We saw it go into a little cove or bathing-tub, where we had just been bathing, where the water was only four or five feet deep at that time, and after exploring it go slowly out again; but we continued to bathe there, only observing first from the bank if the cove was preoccupied. We thought that the water was fuller of life, more aerated perhaps than that of the Bay, like soda-water, for we were as particular as young salmon, and the expectation of encountering a shark did not subtract anything from its life-giving qualities.
Sometimes we sat on the wet beach and watched the beach birds, sand-pipers, and others, trotting along close to each wave, and waiting for the sea to cast up their breakfast. The former (Charadrius melodus) ran with great rapidity and then stood stock still remarkably erect and hardly to be distinguished from the beach. The wet sand was covered with small skipping Sea Fleas, which apparently make a part of their food. These last are the little scavengers of the beach, and are so numerous that they will devour large fishes, which have been cast up, in a very short time. One little bird not larger than a sparrow,—it may have been a Phalarope,—would alight on the turbulent surface where the breakers were five or six feet high, and float buoyantly there like a duck, cunningly taking to its wings and lifting itself a few feet through the air over the foaming crest of each breaker, but sometimes outriding safely a considerable billow which hid it some seconds, when its instinct told it that it would not break. It was a little creature thus to sport with the ocean, but it was as perfect a success in its way as the breakers in theirs. There was also an almost uninterrupted line of coots rising and falling with the waves, a few rods from the shore, the whole length of the Cape. They made as constant a part of the ocean’s border as the pads or pickerel-weed do of that of a pond. We read the following as to the Storm Petrel (Thalassidroma Wilsonii), which is seen in the Bay as well as on the outside. “The feathers on the breast of the Storm Petrel are, like those of all swimming birds, water-proof; but substances not susceptible of being wetted with water are, for that very reason, the best fitted for collecting oil from its surface. That function is performed by the feathers on the breast of the Storm Petrels as they touch on the surface; and though that may not be the only way in which they procure their food, it is certainly that in which they obtain great part of it. They dash along till they have loaded their feathers and then they pause upon the wave and remove the oil with their bills.”
Thus we kept on along the gently curving shore, seeing two or three miles ahead at once,—along this ocean side-walk, where there was none to turn out for, with the middle of the road the highway of nations on our right, and the sand cliffs of the Cape on our left. We saw this forenoon a part of the wreck of a vessel, probably the Franklin, a large piece fifteen feet square, and still freshly painted. With a grapple and a line we could have saved it, for the waves repeatedly washed it within cast, but they as often took it back. It would have been a lucky haul for some poor wrecker, for I have been told that one man who paid three or four dollars for a part of the wreck of that vessel, sold fifty or sixty dollars’ worth of iron out of it. Another, the same who picked up the Captain’s valise with the memorable letter in it, showed me, growing in his garden, many pear and plum trees which washed ashore from her, all nicely tied up and labelled, and he said that he might have got five hundred dollars’ worth; for a Mr. Bell was importing the nucleus of a nursery to be established near Boston. His turnip-seed came from the same source. Also valuable spars from the same vessel and from the Cactus lay in his yard. In short the inhabitants visit the beach to see what they have caught as regularly as a fisherman his weir or a lumberer his boom; the Cape is their boom. I heard of one who had recently picked up twenty barrels of apples in good condition, probably a part of a deck load thrown over in a storm.
Though there are wreck-masters appointed to look after valuable property which must be advertised, yet undoubtedly a great deal of value is secretly carried off. But are we not all wreckers contriving that some treasure may be washed up on our beach, that we may secure it, and do we not infer the habits of these Nauset and Barnegat wreckers from the common modes of getting a living?
