ПЕРЕВОД:
Tom and Becky stayed home for many days. Then, two
weeks after their adventure, Tom visited Becky and talked
to her father.
Mr. Thatcher said, “You're a very good boy, Tom. You
helped Becky in the cave. Thank you. People can't go into
it now because it has a new big door.”
“But Injun Joe's living in the cave!” Tom said.
Some men went down the river to the cave. Tom went
with them. They opened the new door. Injun Joe was
there, but he was dead.
Tom wanted to talk to Huck. Later in the week he went
to MI
Jones's house. The two boys talked about their
adventures.
“The money isn't in Injun Joe's house," Tom said. “It's
in the cave! I know, because Injun Joe was there. Let's get
it!”
Huck was afraid. “But maybe we can't find it.”
"I can find it again,” Tom said. “I know about a small
door at the back of the cave. Becky and I came out there.
We can go in that door, and I can find Injun Joe's treasure.”
“OK,” Huck said. “Let's go tođay.”
That afternoon the boys went in a small boat to the back
of the cave. Tom walked first, and Huck went after him.
They walked and walked.
وو
Then Tom said, “This is the right place! Injun Joe was
here.”
The boys looked for a good place for treasure.
Suddenly, Tom said, “Look! There's a cross! Injun Joe
said, 'under the cross.' Let's look there!"
