Wrought by man’s art to be compared to them;

Soft, brilliant, tender, through the wave they glow,

And make the moonbeams brighter where they flow.

Involved in sea-wrack, here you find a race

Which science doubting, knows not where to place.

On shell or stone is dropped the embryo seed,

And quickly vegetates a vital breed;

While thus with pleasing wonder you inspect

Treasures the vulgar in their scorn reject.”
