The diamond mines
In this chapter
Into the mines by the funnel, the wrench mends the elevator control machine, Grand Dizzy's elevator key, and the dynamite blows a wall in the deepest tunnels.
At the far left of Silver Stream, a funnel in the ground drops Dizzy into the diamond mines, next to the elevator control machine (The way into the mines).
Drop the machine wrench at the machine: it's mended and the mines' lifts work (The mines' elevators don't work). Close by lies the key for Grand Dizzy's elevator.
From the upper corridor, the lift on the far left goes down to a chamber with a gap in its floor; drop through onto the railway level. Its two corridors meet only by the lift in the middle, and the lower corridor's left end drops into the deepest tunnels (Getting deeper into the mines).
Down there, one lift drops to the lowest tunnel and another, at its east end, climbs to a room high on the right with a detonator's plunger. Drop the dynamite by the wall on the room's left, stand at the plunger and press B. Boom: the wall is gone, opening a chamber under something big and grumpy (A wall in the deepest tunnels).
