The Demon of the Reef

The romance of coral has still to be written. There still exists a widespread opinion that the coral reef and the coral island are the work of an "insect." This fabulous insect, accredited with the genius of Brunel and the patience of Job, has been humorously enough held up before the children of many generations as an example of industry--a thing to be admired, a model to be followed.

As a matter of fact, nothing could be more slothful or slow, more given up to a life of ease and degeneracy, than the "reef-building polypifer"--to give him his scientific name. He is the hobo of the animal world, but, unlike the hobo, he does not even tramp for a living. He exists as a sluggish and gelatinous worm; he attracts to himself calcareous elements from the water to make himself a house--mark you, the sea does the building--he dies, and he leaves his house behind him--and a reputation for industry, beside which the reputation of the ant turns pale, and that of the bee becomes of little account.

On a coral reef you are treading on rock that the reef-building polypifers of ages have left behind them as evidences of their idle and apparently useless lives. You might fancy that the reef is formed of dead rock, but it is not: that is where the wonder of the thing comes in--a coral reef is half alive. If it were not, it would not resist the action of the sea ten years. The live part of the reef is just where the breakers come in and beyond. The gelatinous rock-building polypifers die almost at once, if exposed to the sun or if left uncovered by water.
