Exploring the sands on the beach, Tonya III man came across a lidless boule. She picked it up, looked inside and noticed something. She turned it upside down. Out came a damp, neatly rolled piece of paper. Tonya took it home, dried and unrolled it.

What caught her eye was the year field, 18      . Though at first sceptical of finding something this old so easily, she continued reading. It began with some coordinates (坐标). Below was a request in German asking the bolded finder to put down the date and location of where it was found and return it to the nearer German embassy.

The Illmans took the note Rosa Anderson, a curator (馆长) at the Western Australian Museum. Soon Anderson called, saying he had been able to locate a 19th - century ship named Paula. Even more exciting was that experts in Germany were able to track down Paula’s logbooks and find a record by a “Captain O. Diekmann,” confirming that a bottle had been thrown overboard on June 12. 1886 - the date on the message. The sailor had also listed the coordinates of the ship’s location, which matched the ones on the note. Another evidence of the note’s truth was the logbook’s neat script (手稿), which paired perfectly with that of the handwritten message. The records also indicated that the bottle was one of the thousands thrown by the seamen back then as part of an experiment to track the water currents.

Anderson believes the note remained undamaged because it was put in a strong bottle with a narrow opening which allowed little water in, even after the lid came off. The expert guessed it had been probably washed ashore and remained buried in the thick sand.

The 131 - year - old note, now lying in the Western Australia Museum, was confirmed as the oldest message in a bottle ever discovered.
