In the tenth century A.D., Mingti, one of the most extravagant of the early monarchs, used so many pearls—not only in his personal decoration but on his equipage and retinue,—that after a formal procession the way would be rich in the jewels which dropped from the gorgeous cortège. About 1000 A.D., an embassy to the emperor brought as tribute an ornament composed of strings of pearls, and also 105 liang (8¾ lbs.) of the same gems unmounted.
An interesting story is told of “pearl-scattering” by an embassy to the Chinese court from a Malayan state about 1060. Following the customs of their country, the ambassadors knelt at the threshold of the audience chamber, and then advanced toward the throne, bearing a golden goblet filled with choice pearls and water-lilies wrought of gold. These they scattered upon the floor at the feet of the emperor; and the courtiers, hastening to pick them up, secured ten hang (15 oz.) of pearls.[[171]]
The Keh Chi King Yuen, a Chinese encyclopedia, describes a pearl fishery in the southern part of Kwang-tung province, in the department of Lien-chau and near the city of Hóhpú. Fishing began in the spring, and was preceded by conciliating the gods through certain sacrifices, in order that the weather might be propitious and that no disaster might be suffered through sharks and other agencies. The five sacrificial animals,—horses, cattle, sheep, swine, and fowls,—were presented; but ordinarily paper images of these were economically substituted, as equally acceptable to the Chinese rulers of destiny. In the details of the diving, the fishery resembled somewhat that prosecuted about the same period in the Gulf of Manaar. The diver was let down by a rope, and after collecting the mollusks and placing them in a basket, he was drawn up at a given signal. Much complaint was made that the divers would open the mollusks, extract the pearls and conceal them in the mouth before returning to the surface.
The business became so perilous and the loss so great, that about the beginning of the sixteenth century, according to the same encyclopedia, dredges were adopted. These at first were simple rakes; later large dredges were trailed along between two boats, by means of which great quantities of shells were gathered. So important was the industry that an officer was designated by the viceroy of Canton to collect a revenue therefrom. It does not appear that pearls have been collected in considerable numbers on this part of the Chinese coast for very many years, probably not since the advent of Europeans.
Pearls are yet found in the river mussels in all parts of eastern Asia, from Siberia to the Indian Ocean, and from the Himalayas to the Pacific. It is represented that they are not from the Unio margaritifera, the common river-mussel of Europe, but from other species, such as Unio mongolicus, U. dahuricus, Dipsas plicatus, etc. It is quite impossible to obtain a reliable estimate of the total number of persons employed, or the output of pearls in China, but these items are certainly very much larger than the average Occidental believes.
In the vicinity of Canton the Dipsas plicatus has been used for centuries by the Chinese in the production of artificial pearls, this industry giving employment to thousands of persons.[[172]]
The pearl-mussel fishery is of importance in Manchuria, where it has been carried on for hundreds of years, not only by the citizens, but by the military department on account of the government, and especially in the streams which flow into the Songari, a tributary of the Amur. Jacinth relates that in case of a deficit, the officers and subalterns were punished by a deduction from their pay, and also by corporal chastisement.[[173]] Witsen speaks of the pearls from the River Gan, a tributary of the Amur, and also from the islands of the Amur, the boundary river of Manchuria. Pearl fisheries were established at these places by the Russians nearly two centuries ago.[[174]]
Pearls become finer and more plentiful the further we penetrate into Manchuria; and they are numerous in the lake of Heikow or Hing-chou-men, “Black Lake” or “Gate of Precious Gems,” where they have long been exploited for the account of the emperor of China.
The occurrence of pearls in many parts of Asiatic Russia was noted by Von Hessling. In northern Siberia, according to Witsen, writing in 1705,[[175]] pearls were found in the waters about the town of Mangasea on the Turuchan; and Von Middendorf notes that they were found in the Tunguska River, which flows into the Yenisei. Whether, however, they come from the Unio margaritifera is considered doubtful by Von Middendorf. Witsen referred to their occurrence in the rivers and streams of Irkutsk and Onon, and this is confirmed by several writers of more recent times. Pallas says that the mussels found there are quite large, and speaks of the Ilim, which flows into the Angara, as another river where they occur.
Ancient books relating to Japan repeatedly allude to the occurrence of pearls on the coasts of that country. They are mentioned in the Nihonki, of the eighth century, the oldest Japanese history.
