REAL VS. NOT-SO-REAL
309
The cultured pearl is, like the natural pearl, the product of a living organism, though its beginning was false. This organ­ism may be irritated or stimulated in such a manner as to bring about certain desired results, but it is by no means a foregone conclusion that these will come up to expectation. In fact, as I have said, we know they do not. Color, shape, luster, and cleanness cannot be predetermined. They are, in the cultured pearl, no less than in the natural, conditioned by factors of which we know nothing and over which we have therefore no control.
Perfection in all of these combined qualities cannot possibly occur oftener in the cultured than in the natural pearl because, as we have seen, their causes are not amenable to man's disci­pline. The secrets of their shape and beauty are perhaps the secrets of the whole sea-floor; every force at Neptune's com­mand may be brought to bear, temperately and kindly, upon these supremely lovely children of ocean. No culture-station could ever reproduce intentionally the collaboration of forces that go to the making of a single perfect pearl. So far as the Japanese cultured pearl is concerned, this is illustrated by the fact that no science whatever could make an oyster of the variety found in Japanese waters reproduce a pearl of quality and orient to compare with those from the Persian Gulf. Natural or cultured pearls fished from any particular locality must always bear—as I have explained already—their birth certificate on their face.
Again, the Japanese lingah is as subject to the ravages of the starfish, the boring whelk, and other pests as are pearl-oysters in other parts of the world. Moreover, an epidemic of some kind or a ruthless typhoon may any day destroy some, if not all, of the culture-beds at a blow. This has happened elsewhere to natural pearl-beds, and why should it not happen in Japan, in spite of the many years' work and thought that are lavished upon the artificial grounds?
In pearls of small size, the Japanese culture-stations can­not, in any case, compete with the pearl-fisheries, whose output in small pearls is obtainable at nrices at which culture-stations
