Get a big candle composed of human tallow, and fix it into a piece of hazel-wood fashioned in the shape of a U. Then, if this candle, being lighted in a subterranean place, sparkles brightly with a good deal of noise, it is a sign that there is treasure in that place, and the nearer you approach the treasure the more the candle will sparkle, going out at length when you are quite close (you must have other candles/lanterns so you wont be left without light). When there is sound reason for believing that treasure is watched over by the spirits of the dead it is good to have wax candles which have been blessed instead of common candles, and to conjure the spirits in the name of God to declare whether there is anything you can do to help them rest*

*if you conjure/ask, you have to do what they say
