The Adventures of Huckleberry Finn
where do jim and huck take their friends in chapter 2
Tom and Huck take their friends a few miles down the river to a cave. Once there, they all swear allegiance to Tom Sawyer's Gang.
"So we unhitched a skiff and pulled down the river two mile and a half, to the big scar on the hillside, and went ashore.
We went to a clump of bushes, and Tom made everybody swear to keep the secret, and then showed them a hole in the hill, right in the thickest part of the bushes. Then we lit the candles, and crawled in on our hands and knees. We went about two hundred yards, and then the cave opened up. Tom poked about amongst the passages, and pretty soon ducked under a wall where you wouldn't a noticed that there was a hole. We went along a narrow place and got into a kind of room, all damp and sweaty and cold, and there we stopped. Tom says: "Now, we'll start this band of robbers and call it Tom Sawyer's Gang. Everybody that wants to join has got to take an oath, and write his name in blood."
The Adventures of Huckleberry Finn/ Chapter 2
