How much does the fish weigh? The Creachams planned to stop during their journey at a place with good fishing, as Uncle Jabez was an avid fisherman and they wanted to please him. They chose a charming spot and took the opportunity to have a picnic there. When Uncle brought a magnificent trout, a discussion arose about how much it might weigh. The colonel presented it as a puzzle, saying:

- Suppose the tail weighs 9 ounces, the head weighs as much as the tail plus half the body, and the body weighs as much as the head and tail.

Now tell me, if all this is true, how much does the fish weigh?
