Those ghost-like Prawns are near relatives of the giant. See them, gliding so gracefully from under the arch, disappearing under the waving Ulva, and floating into sight again from behind the cliff. At night, if you look at them athwart a lighted candle, their eyes are seen to glow like living rubies. As they row silently and swiftly towards you, you might fancy each a fairy gondola, with gem-lighted prow.
A quick dashing startles you, and you see a Scallop rising to the top of the water with zigzag jerks, and immediately sinking to the sand again, on the side opposite that whence it started. There it rests with expanded branchiae and moving cilia; a rude passer-by jostles it, and with startled sensitiveness it shrinks from the outer world and hides behind a stony mask.
The small, greenish, rough-coated creature, so like a flattened burr, is an Echinus. It is hardly domiciliated, being a new-comer, and creeps restlessly across the glass.
Under this sand-mound some one lies self-buried,--not dead, but only hiding from the crowd in this bustling watering-place. He must learn that there is no lasting retirement in Newport; so tap with a stick at his lodging. With anger vexed, forth rushes the Swimming-Crab and dashes away from the unwelcome visitor. As if he knew a bore to be the most persistent of hunters, he plies his paddles with rapid beat until far from his invaded chamber. His swimming is more like the fluttering of a butterfly than the steady poise of a fish. Pretty as is his variegated coat by day, it is far more beautiful by night; then his limbs shine with metallic lustre, and every joint seems tinged with molten gold.
I could spend the day in showing you my Aquarium;--the merry antics of the blithe Minnows; the slow wheeling of the less vivacious Sticklebacks; the beautiful siphon of the Quahaug and the Clam; the starry disk of the Serpula; the snug tent of the Limpet; the lithe proboscis of the busy Buccinum; the erect and rapid march of his little flesh-tinted cousin; the slow Horsefoot, balancing his huge umbrella as he goes; the----But I cannot name them all.
Neither could you learn to know them at a single visit. Come and sit by this indoor sea, day by day, and learn to love its people. Many a lesson for good have they taught me. When weary and disheartened, the patient perseverance of these undoubting beings has given me new impulses upward and onward. Remembering that their sole guide is instinct, while mine is the voice behind me, saying, "This is the way," I have risen with new resolve to walk therein. Seeing the blind persistency with which some straying zoöphyte has refused to follow other counsel than its own, I have learned that self-reliance and strength of will are not, in higher natures, virtues for gratulation, but, if unsanctified, faults to blush for. Finding each creature here so fitted with organs and instincts for the life it was meant to lead, I have considered that to me also is given all that I ought to wish, more than I have ever rightly used.
