CHAPTER LXXII

MOTHER-OF-PEARL AND PEARLS

“SOME of the shells you have just shown us,” said Jules, “shine inside

like the handle of that pretty penknife you bought me the day of the

fair—you know?—that four-bladed penknife with the mother-of-pearl

handle.”

“That is plain enough. Mother-of-pearl, that pretty substance that

shines with all the colors of the rainbow, comes from certain shells. We

use for delicate ornamentation what was once the dwelling of a glairy

animal, near relation to the oyster. Truly, this dwelling is a veritable

palace in richness. It shines with all imaginable tints, as if the

rainbow had deposited its colors there.

“This is the shell that furnishes the most beautiful mother-of-pearl. It

is called the meleagrina margaritifera. Outside it is wrinkled and

blackish-green; inside it is smoother than polished marble, richer in

color than the rainbow. All tints are found there, bright, but soft and

changeable, according to the point of view.”

“That superb shell is the house of a miserable, slimy animal! In fairy

tales the fairies themselves have none to equal it. Oh! how beautiful,

how beautiful it is!”

“Every one has his portion in this world. The slimy animal has for his a

splendid palace of mother-of-pearl.”

“Where does the meleagrina live?”

“In the seas that wash the shores of Arabia.”

“Is Arabia very far away?” inquired Emile.

“Very far, my dear. Why do you ask?”

“Because I should like to pick up a lot of these beautiful shells.”

“Don’t dream of such a thing. It is too far away, and, besides, they are

not to be gathered by every one that wants them. To get the meleagrina

men have to dive to the bottom of the sea, and some of them never come

up again.”

“And there are people who dare to dive to the bottom of the sea just to

get shells?” asked Claire.

“Plenty. So profitable, too, is the trade that we should be badly

received by the first-comers if we took a notion to go and fish with

them.”

“Then those shells are very precious?”

“You shall judge for yourself. First the inner layer of the shell, sawed

into sheets and tablets, is the mother-of-pearl that we use for fine

ornamentation. Jules’ penknife-handle is covered with a sheet of

mother-of-pearl that was part of the inside of a pearl-shell. But that

is the least part of what the precious shell produces. There are pearls

as well.”

“But pearls are not very dear. With a few sous I bought a whole boxful,

to embroider you a purse.”

“Let us make a distinction: there are pearls and pearls. The pearls you

mention are little pieces of colored glass pierced with a hole. Their

price is very moderate. The pearls of the meleagrina are globules of the

richest and finest mother-of-pearl. If they are unusually large, they

attain the fabulous price of the diamond, up to hundreds of thousands

and millions of francs.”

“I don’t know those pearls.”

[Illustration: Oyster Shell]

“God keep you from ever knowing them, for in becoming interested in

pearls one sometimes loses common sense and honor. It is well, though,

to know how they are produced.

“Between the two parts of the shell lives an animal like the oyster. It

is a mass of slime in which you would find it difficult to recognize an

animal. It digests, however, and breathes, and is sensitive to pain, so

sensitive that a grain of dust, a mere nothing, renders existence

painful to it. What does the animal do when it feels itself tickled by

some foreign substance? It begins to sweat mother-of-pearl around the

place that itches. This mother-of-pearl piles up in a little smooth

ball, and there you have a pearl made by the sick, slimy animal. If it

is of any considerable size, it will cost a fine bag of crowns, and the

person who wears it around her neck will be very proud of it.

“But before getting to the neck, it must be fished for. The fishermen

are in a boat. They descend into the sea, one after another, with the

aid of a rope to which is tied a large stone that drags them rapidly to

the bottom. The man about to dive seizes the weighted rope with his

right hand and the toes of his right foot; with his left hand he closes

his nostrils; to his left foot is fastened a bag-shaped net. The stone

is thrown into the sea. The man sinks like lead. Hastily he fills the

net with shells, and then pulls the rope to give the signal for ascent.

Those in the boat pull him up. Half-suffocated, the diver reaches the

surface with his fishing. The efforts he has made to suspend respiration

are so painful that sometimes blood gushes from his mouth and nose.

Sometimes, the diver comes up with a leg gone; sometimes he never comes

up. A shark has swallowed him.

“Some of those pearls that shine in a jeweler’s windows cost much more

than a fine bag of crowns: they may have cost a man’s life.”

“If Arabia were at the end of the village, I would not go

pearl-fishing,” declared Emile.

“To open the shells, they are exposed to the sun until the animals are

dead. Then men rummage in the pile, which smells horribly, and get the

pearls. There is nothing more to do except pierce them with a hole.”

“One day,” said Jules, “when they were cleaning the big mill-race I

found some shells that shone inside like mother-of-pearl.”

“We have in our streams and ditches shells in two parts of a greenish

black. They are called fresh-water mussels. Their inside is

mother-of-pearl. Some, very large and living by preference in mountain

streams, even produce pearls. But these pearls are far from having the

luster and consequently the price of those of the meleagrina.”
