Chocolate Oil Fields

Another time, as they were passing some sort of a vast red plain dotted with things that looked like oil derricks, he saw a great spout of brown liquid spurting out of the ground high into the air. 'A gusher!' cried Mr Wonka, clapping his hands. 'A whacking great gusher! How splendid! Just when we needed it!'

'A what?' said Charlie.

'We've struck chocolate again, my boy. That'll be a rich new field. Oh, what a beautiful gusher! Just look at it go!'
