Dreams of finding lost treasure almost
came true recently. A new machine called
'The Revealer' has been invented and it
has been used to detect gold which has
been buried in the ground. The machine
was used in a cave near the sea-shore
where--it is said--pirates used to hide
gold. The pirates would often bury gold
in the cave and then fail to collect it.
Armed with the new machine, a search
party went into the cave hoping to find
buried treasure. The leader of the party
was examining the soil near the entrance
to the cave when the machine showed
that there was gold under the ground.
Very excited, the party dug a hole two
feet deep. They finally found a small gold coin which was almost worthless. The
party then searched the whole cave thoroughly but did not find anything except
an empty tin trunk. In spite of this, many people are confident that 'The
Revealer' may reveal something of value fairly soon.
