In a few minutes, as the Child was gazing idly over the rocks, he observed on the top of one of them a number of little shells opening and shutting under the shallow water, whilst through the openings little feathery heads kept darting in and out.
"Are you limpets?" he asked.
"No connection," was the reply.
"Oh, I thought you were limpet shells broken and mended," said the Child. "Are you related to the builders of the sand-bridges?"
"Not at all," answered the feathery heads. "We are Balanuses. In our youth we were great voyagers, and floated about on the waves. But now we have grown wiser. We have thrown off our legs and eyes, and built ourselves these little chambers with folding-doors, and are settled down respectably for life."
The Child could scarcely help laughing at the idea of any one finding it a comfort to throw away his legs and eyes; but he thought it would not be respectful towards elderly gentlemen, who had seen so much of the world, so he said, as gravely as he could, "Was it not pleasant dancing about among the great waves?"
"Very well for young people," was the answer, "or for those who cannot provide for themselves otherwise; but to have a drawing-room with folding-doors, and stay at home when it is dry, or feel about when it is wet, just as one likes, is quite a different thing."
And the little heads swayed about so happily, making tiny whirlpools to suck in their food, that the Child had no doubt they were as happy as they could be, and wisely resolved to be the same.
So the thin cloud of discontent was blown away, though not the desire to see the far-off wonders; and as he sat and watched in happy silence, the soft music of the living creatures again broke on his ear. And as he looked and listened, new wonders burst on him, new doors of beauty kept springing open in the fairy palace of the rock-pool. Hairy stems of the large brown sea-weeds blossomed, as he looked, into a thousand little living stars, vibrating their sensitive rays to and fro in the crystal water. The scales which spotted them proved to be a honeycomb of countless cells, every one of which had its little living busy tenant; and a tiny withered-looking stalk, with knobs at the end of the branches, suddenly shot out from each little knob numbers of busy little fingers, feeling in all directions for food,—whilst through all flowed the sweet solemn song, so that the Child lingered in happy wonder until the little creeks grew invisible in the shade and the water plashed with a cold sound. The little rock-borers kindled their bluish-white lamps, in the depths of their tiny caves, to light him home; and when he reached the mossy bank, the glow-worms were awaiting him with their rows of coloured lamps, illuminating the mossy bank as for a festival; and the rock-pools shone like steel mirrors, with a cold gray light, among the dark rocks. Then he returned to his cave.
But still the longing grew within him to learn the words of the Song, and he thought, "I wonder if they could teach it me far out on the deep sea?"
