NEWPORT BEACH

Newport has many beaches, each bearing a distinctive appellation. To the one of which we are speaking rightfully belongs the name of Easton; but it is more widely known by that of the town itself, and still more familiarly to the residents as "The Beach." It lies east of the city, a mile from the harbor, and is about half a mile in length. Its form is that of the new moon, the horns pointing southward.

Let us go there now. No better time could be chosen by the naturalist, for the tide will be at its lowest ebb. Descending Bath Road, the beautiful crescent lies before us on the right,—Easton's Pond, with its back-ground of farms, upon the left. There is no wind to-day to break the surface of the standing water, and it gives back the dwarf willows upon its banks and the houses on the hill-side with more than Daguerrian fidelity. The broad ocean lies rocking in the sunshine, not as one a-weary, but resting at his master's bidding, waiting to begin anew the work he loves. In the horizon, the ships, motionless in the calm, spread all sail to catch the expected breeze. The waves idly chase each other to the shore, in childish strife to kiss first the mother Earth.

Turning the sea-wall and crossing a bit of shingle on the right, we stand upon the western extremity of the beach.

At our feet, a smooth, globular object, of the size of a crab-apple, is lying half-buried in the sand. Taking it in your hand, you find it to be a univalve shell, the inhabitant of which is concealed behind a closely-fitting door, resembling a flake of undissolved glue.

It is a Natica. Place it gently in this pool and watch for a few moments. Slowly and cautiously the horny operculum is pushed out, turned back, and hidden beneath a thick fleshy mantle, which spreads over half the shell. Two long tentacles appear upon its front, like the horns of an ox, and it begins to glide along upon its one huge foot.

Had you seen it thus at first, you could not have believed it possible for so bulky a body to be retracted into so small a shell. Lift it into the air, and a stream of water pours forth as it contracts.

Two kinds are common here, one of which has a more conical spire than the other. The animals differ somewhat in other points, but both have a cream-colored base, and a mantle of pale cream clouded with purple. You may get them from half an inch to three inches in diameter. Take them home and domesticate them, and you will see surprising things.

I kept one of middling size for many months. During two or three weeks I wondered how he lived, for he was never seen to eat. He used to climb to the top of the tank and slide down the slippery glass as though it were a montagne russe. Then he would wander about upon the bottom, ploughing deep furrows in the sand, and end by burrowing beneath it. There he would stay whole days, entirely out of sight.

One morning I found him on his back, his body bent upward, with the edge of the base turned in all round towards the centre. Did you ever see an apple-dumpling before it was boiled, just as the cook was pinching the dough together? Yes? Then you may imagine the appearance of my Natica; but no greening pared and cored lay within that puckered wrapper.

Two days passed with no visible change; but on the third day the strange gasteropod unfolded both himself and the mystery. From his long embrace fell the shell of a Mactra, nearly as broad as his own. Near the hinge was a smooth, round hole, through which the poor Clam had been sucked. Foot, stomach, siphon, muscles, all but a thin strip of mantle, were gone. The problem of the Natica's existence was solved, and the verification was found in more than one Buccinum minus the animal,—the number of the latter victims being still an unknown quantity.

Not in sport had Natty driven the plough, not in idleness had he hollowed the sand. He sought his food in the furrow, and dug riches in the mine.

Doubtless he killed the bivalve,—for until the time of its disappearance it had been in full vigor,—but with what weapon? And whereabouts in that soft bundle was hidden the wimble which bored the hole?

A few days after, a Crab, of the size of a dime, died. Nat soon learned the fact, and enveloped the crustacean as he had done the mollusk. Thirty hours sufficed to drill through the Crab's foundation-wall, and to abstract the unguarded treasure.

Every week some rifled Trivittatum tells a new tale of his felonious deeds.

His last feat was worthy of a cannibal, for it was the savage act of devouring a fellow-Natica. You might suppose that in this case the trap-like operculum would afford an easy entrance to one familiar with its use; but, true to his secret system, the burglar broke in as before. How did he do this? Did he abrade the stone-work with flinty sand until a hole was worn? Did he apply an acid to the limy wall until it opened before him? Who can find the tools of the cunning workman, or the laboratory where his corrodents are composed?

Some rods farther south, the shore is covered with smooth stones, and there you may find the Limpet in great numbers. Patella is the Latin name, but children call it Tent-Shell. Oval at the base, it slopes upward to a point a little aside from the centre.

In this locality they are small, seldom more than an inch in length. At first, you will not readily distinguish them, they are so nearly of the color of the stones to which they are attached. This is one of those Providential adjustments by which the weak are rendered as secure as the strong. Slow in their movements, without offensive weapons, their form and their coloring are their two great safeguards. The stones to which they adhere are variegated with brown and purple blotches of incipient Coralline, and the shells are beautifully mottled with every shade of those colors. Some are lilac, heightening nearly to crimson; others are dark chocolate and white, sharply checkered.

Pebbles and Patella alike are half-covered with Confervae, and from the top of the latter, fronds of Ulva are often found floating like flags. I have one with a clump of Corallina rising from its apex, like a coppice on the summit of a hill.

By atmospheric pressure, its union with the stone is so close that it is not easy to pull it away without injury; but if you slip it along, until by some slight inequality air is admitted beneath the hitherto exhausted receiver, the little pneumatician is obliged to yield.

When turned upon its back, or resting against glass, the soft arms, sprawling aimlessly about, and the bare, round head, give it the appearance of an infant in a cradle, so that a tank well stocked with them might be taken for a Liliputian foundling-hospital.

They are as innocent as they look, being vegetable-feeders, and finding most of their sustenance in matters suspended in the water. A friend of mine placed several upon the side of a vessel coated with Conferva. In a few days, each industrious laborer had mowed round him a circular space several times larger than himself.

They are not ambulatory, but remain on one spot for successive weeks, perhaps longer.

Sometimes they raise the shell so as to allow a free circulation beneath; but if some predatory Prawn draw near, the tent is lowered in a twinkling, so as effectually to shut out the submarine Tartar.

Tread warily, or you will trip upon the slimy Fucus that fringes the seaward side of every rock. This is one of the few Algae that grow here in luxuriance. The slate has not the deep fissures necessary to afford shelter to the more delicate kinds; and the heavy swell of the sea drags them from their slight moorings. Therefore, though Ulva, Chondrus, Cladophora, Enteromorpha, and as many more, are within our reach, we will not stop to gather them; for Newport has other shores, where we can get them in full perfection.

We will take some tufts of Corallina, however, for that is temptingly fine. What a curious plant it is! Its root, a mere crustaceous disk, and its fronds, depositing shelly matter upon their surface, bear so strong a resemblance to the true Corals, that, until recently, naturalists have thought it a zoophyte.

Here the plants are of a dull brick-red; but in less exposed situations they are purple. If you wish them to live and increase, you must chip off a bit of the rock on which they are growing. With a chisel, or even a knife, you can do it without difficulty, for the soft slate scales and crumbles under a slight blow.

For an herbarium, it ought to be gummed at once to the paper, for it becomes so brittle, in drying, that it falls to pieces with the most careful handling. In the air and light it fades white, but the elegance of its pinnate branches will well repay any pains you may bestow upon it.

If you have a lingering belief in its animal nature, steeping it in acid will cause the carbonate of lime and your credulity to disappear together, leaving the vegetable tissue clearly revealed.

Between low-water and the Cliff are hundreds of pools rich in vegetable and animal life—Look at this one: it is a lakelet of exquisite beauty. Bordered with the olive-colored Rock-Weed, fronds of purple and green Laver rise from its limpid depths. Amphipods of varied hue emerge from the clustering weeds, cleave the clear water with easy swiftness, and hide beneath the opposite bank. Here a graceful Annelid describes Hogarth's line of beauty upon the sandy bottom. There another glides over the surface with sinuous course, rowed by more oars than a Venetian galley, more brilliant in its iridescence than the barge of Cleopatra, albeit

We loiter here, forgetful that we are only at the first end of the bow along whose curve we propose to walk. Let us go on. The firm sand affords pleasanter footing than the slippery stones we leave behind us, but it seems bare of promise to the curiosity-hunter. Nevertheless we will hunt, and quite at variance with my experience will it be, if we return empty-handed.

Here is something already. Dark-colored, horny, flat, oblong, each corner furnished with a wiry, thorn-like projection;—what is it? A child tells you it is a Mermaid's Purse, and, giving the empty bag a shake, you straightway conclude that the maids of the sea know "hard times," as well as those of the land. But the Purse is not always so light. Sometimes it is found to contain a most precious deposit, the egg which is to produce a future fish.

These egg-cases belong to different members of the Ray family. I saw one last winter, in which the inmate was fully developed. Should some old seaman hear me, he might say that I am telling a "fish-story" in good earnest. He might inform you furthermore, that the object in question is "but a pod of sea-weed, and that he has seen hundreds of them in the Gulf Stream." I cannot help it, neither do I question his veracity. Notwithstanding, these two eyes of mine, in sound condition, awake, and in broad day, did see the supposed pericarp, with one side taken off, and did behold, lying within, as veritable a Raia as ever was caught upon the New-England coast. Moreover, its countenance was no more classical, in its minuteness, than that of its most ancient ancestor in its hugeness.
