Here is a newspaper report about the treasure. Find the ten mistakes and correct them.

Corrected Newspaper Report:

Two children, Tom Sawyer and Becky Thatcher, found twelve thousand dollars in a bag in McDougal's Cave. Injun Joe found the money under a tree and put it in a small opening at the end of a tunnel. He marked the floor of the cave with a cross. But then he couldn't get out of the cave because of the entrance being blocked at the mouth of the cave. When the men found him, he was dead, so there won't be a trial.

Mistakes:

1. 'twelve hundred' should be 'twelve thousand'
2. 'McDougal's' should be 'McDougal's'
3. 'Muff Potter' should be 'Injun Joe'
4. 'big room' should be 'small opening'
5. 'tunnel' should be 'cave'
6. 'ghosts' should be 'entrance being blocked'
7. 'alive' should be 'dead'
8. 'is' should be 'won't'
