TREATMENT AND CARE OF PEARLS 399
too long boiled in the opening of the shell, or where they have been swallowed and have passed through the body of some ruminant, such as a hog, etc.
Probably about no necklace has more been printed than about the famous necklace of Madame Thiers, now in the Louvre Museum of Paris. Article after article has gone over the face of the earth, stat­ing that the pearls in this necklace were dying, and that a record was being kept of the slow death that was overtaking them. Through the courtesy of the director of the museum, M. Gaston Mogeaud, we are permitted to reproduce the following statement from a letter, showing very clearly that there is absolutely no truth in the assertion, and that this necklace has in no way suffered, or is likely to suffer, for many years to come.
"The necklace of Madame Thiers has caused much ink to flow, to such an extent that, a few months ago, the minister ordered an ex­amination to be made by three expert jewelers, who have found that the pearls are in perfect condition, and have never been in better health."
For assuring the safety of jewels there are the primitive methods such as are used in the East Indies, of hiding pearls in out-of-the-way places, where they often escape detection; or else they may be pro­tected by means of an armored room, like the gem-room that con­tained the wonderful collection of the Duke of Brunswick when he resided in Paris. Decoy necklaces have even been made to represent the original, and so placed that they were taken away by the highway­man or stolen by the burglar under the belief that he was stealing the jewels ; while in other cases the pearls have been carried in receptacles that would not be taken for jewel-caskets, a device resorted to by some travelers.
A word in regard to the former system of strong boxes or small safes for the home. These protect from fire and from the ordinary thief, but they have sometimes not proved so invulnerable to the expert cracksman. Quite recently a jewel chest has been devised which can be placed in a trunk and carried from city to city by the owner. It is provided with an exceedingly sensitive electrical apparatus, by means of which a loud burglar alarm is set off should the chest be lifted even one thirty-second of an inch or jarred ever so slightly. This alarm is set automatically when the owner turns the key, and if once started, it will ring for a couple of hours, stopping only when the box is unlocked, thus preventing the carrying away of what is otherwise a portable box.
Lastly, there are the more advanced methods, in use during the past two centuries, such as taking the jewels to a banker and allowing him to place them in his vault, where they are guarded as well as are his
