"My worthy Ned," I answered, "to the poet, a pearl is a tear of the sea; to the Orientals, it is a drop of dew solidified; to the ladies, it is a jewel of an oblong shape, of a brilliancy of mother-of-pearl substance, which they wear on their fingers, their necks, or their ears; for the chemist, it is a mixture of phosphate and carbonate of lime, with a little gelatine; and lastly, for naturalists, it is simply a morbid secretion of the organ that produces the mother-of-pearl among certain bivalves."
"Branch of mollusca," said Conseil, "class of acephali, order of testacea."
"Precisely so, my learned Conseil; and, among these testacea, the earshell, the tridacnæ, 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 mollusk which secretes the pearl is the pearl-oyster, the Meleagrina margaritifera, that precious pintadine. The pearl is nothing but a nacreous 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."
"Are many pearls found in the same oyster?" asked Conseil.
"Yes, my boy. There are some pintadines 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?"
