　　Tokyo: Three snakes, whose poison could kill a person in ten minutes, are guarding a blue star sapphire (蓝宝石)worth nearly six hundred thousand dollars at a Japanese exhibition of jewels sent from an Indian museum.

　　“Normally it would be forbidden to let these poisonous snakes guard exhibiton objects, but it's different this time because the jewels are being exhibited at a hotel. ”a police official said.

　　Exhibition officials said that a person bitten (咬)by one of these snakes would need at least 80m1 of an anti-poison medicine to be saved. Medicine was being kept ready at a nearby hospital.

　　The star sapphire and other valuable jewels worth a total of one million dollars are on show behind glass. Hundreds of visitors came to see the special blue star sapphire and were surprised when they saw the sixty-centimetre-long brown guards.
