This one in the rich salmon-colored robe has all our national propensity for travelling. Wandering restlessly about, she never remains two days on the same spot. Yesterday, she climbed the cliff, and sat looking off upon the water nearly all day long. To-day, she has come down to the sand, where, with base distended, as if in caricature of crinoline, she perambulates the crowded thoroughfare. Here is a semi-twin, one base and two trunks. Shall I call it Janus, for its two faces? or will Chang-and-Eng best distinguish this dual unit? Sometimes, one, with tentacles in-tucked and mouth sealed, seems dozing; while his waking brother is busily waving his arms for food. At another time, you may see them both folded together in sleep, like the Babes in the Woods all bestrewn with leaves. Ah, you should have seen my Amphitrite! She bore her plumy crown so grandly, you would have said she was indeed the queen of Actiniae. But, alas! she could not brook imprisonment, and, pining for the unwalled grottoes of Poseidon, she drooped and died. Behind that sheltering rock, and overhung with sea-weed, there is a dark, deep cave, the chosen abode of Giant Grim. Push one of those soldiers to the mouth of the den and wait the result. At the first movement made by the unwitting trespasser on guarded ground, two long, flexile rods are thrust out, reconnoitring right and left. Two huge claws follow, lighted up by two great glaring eyes. At last the whole creature emerges, seizes the intruder, and bears him swiftly away, far beyond his jealously kept premises. With dogged mien he stalks gravely back to his stronghold. You exclaim, "It is a Lobster!" A lobster truly; but saw you ever a lobster with such presence before? Does he resemble the poor bewildered crustaceans you have seen bunched together at a fish-stall? Bears he any likeness to the innocent-looking edibles you have seen lying on a dish, by boiling turned, like the morn, from black to red? 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.
