“Precisely so, my learned Conseil; and, amongst these testacea the earshell, the tridacnae, the turbots, in a word, all those which secrete mother-of-pearl, that is, the blue, bluish, violet, or white substance which lines the interior of their shells, are capable of producing pearls.”

“Mussels too?” asked the Canadian.

“Yes, mussels of certain waters in Scotland, Wales, Ireland, Saxony, Bohemia, and France.”

“Good! For the future I shall pay attention,” replied the Canadian.

“But,” I continued, “the particular mollusc which secretes the pearl is the pearl-oyster. The pearl is nothing but a formation deposited in a globular form, either adhering to the oyster-shell or buried in the folds of the creature. On the shell it is fast: in the flesh it is loose; but always has for a kernel a small hard substance, maybe a barren egg, maybe a grain of sand, around which the pearly matter deposits itself year after year successively, and by thin concentric layers.” {this paragraph is edited}

“Are many pearls found in the same oyster?” asked Conseil.

“Yes, my boy. Some are a perfect casket. One oyster has been mentioned, though I allow myself to doubt it, as having contained no less than a hundred and fifty sharks.”

“A hundred and fifty sharks!” exclaimed Ned Land.

“Did I say sharks?” said I hurriedly. “I meant to say a hundred and fifty pearls. Sharks would not be sense.”

“Certainly not,” said Conseil; “but will you tell us now by what means they extract these pearls?”

“They proceed in various ways. When they adhere to the shell, the fishermen often pull them off with pincers; but the most common way is to lay the oysters on mats of the seaweed which covers the banks. Thus they die in the open air; and at the end of ten days they are in a forward state of decomposition. They are then plunged into large reservoirs of sea-water; then they are opened and washed.”

“The price of these pearls varies according to their size?” asked Conseil.

“Not only according to their size,” I answered, “but also according to their shape, their water (that is, their colour), and their lustre: that is, that bright and diapered sparkle which makes them so charming to the eye. The most beautiful are called virgin pearls, or paragons. They are formed alone in the tissue of the mollusc, are white, often opaque, and sometimes have the transparency of an opal; they are generally round or oval. The round are made into bracelets, the oval into pendants, and, being more precious, are sold singly. Those adhering to the shell of the oyster are more irregular in shape, and are sold by weight. Lastly, in a lower order are classed those small pearls known under the name of seed-pearls; they are sold by measure, and are especially used in embroidery for church ornaments.”

“But,” said Conseil, “is this pearl-fishery dangerous?”
