The account

For 250 years the Tokugawa shoguns took gold from the tunnels at Toi, second only to Sado in all Japan. The mine is open now, and at the panning hall the deal is brisk and honest: thirty minutes, a pan, warm water, and everything you lift is yours. Thirty flakes in thirty minutes earns the title of Gold Panning Master, and your name in the record.
