Three miles below town the ferryboat stopped at the mouth of a woody hollow and tied up. The crowd swarmed ashore and soon the forest distances and craggy heights echoed far and near with shoutings and laughter. All the different ways of getting hot and tired were gone through with, and by-and-by the rovers straggled back to camp fortified with responsible appetites, and then the destruction of the good things began. After the feast there was a refreshing season of rest and chat in the shade of spreading oaks. By-and-by somebody shouted:

"Who's ready for the cave?"

Everybody was. Bundles of candles were procured, and straightway there was a general scamper up the hill. The mouth of the cave was up the hillside -- an opening shaped like a letter A. Its massive oaken door stood unbarred. Within was a small chamber, chilly as an ice-house, and walled by Nature with solid limestone that was dewy with a cold sweat. It was romantic and mysterious to stand here in the deep gloom and look out upon the green valley shining in the sun. But the impressiveness of the situation quickly wore off, and the romping began again. The moment a candle was lighted there was a general rush upon the owner of it; a struggle and a gallant defence followed, but the candle was soon knocked down or blown out, and then there was a glad clamor of laughter and a new chase. But all things have an end. By-and-by the procession went filing down the steep descent of the main avenue, the flickering rank of lights dimly revealing the lofty walls of rock almost to their point of junction sixty feet overhead. This main avenue was not more than eight or ten feet wide. Every few steps other lofty and still narrower crevices branched from it on either hand -- for McDougal's cave was but a vast labyrinth of crooked aisles that ran into each other and out again and led nowhere. It was said that one might wander days and nights together through its intricate tangle of rifts and chasms, and never find the end of the cave; and that he might go down, and down, and still down, into the earth, and it was just the same -- labyrinth under labyrinth, and no end to any of them. No man "knew" the cave. That was an impossible thing. Most of the young men knew a portion of it, and it was not customary to venture much beyond this known portion. Tom Sawyer knew as much of the cave as any one.

The procession moved along the main avenue some three-quarters of a mile, and then groups and couples began to slip aside into branch avenues, fly along the dismal corridors, and take each other by surprise at points where the corridors joined again. Parties were able to elude each other for the space of half an hour without going beyond the "known" ground.

By-and-by, one group after another came straggling back to the mouth of the cave, panting, hilarious, smeared from head to foot with tallow drippings, daubed with clay, and entirely delighted with the success of the day. Then they were astonished to find that they had been taking no note of time and that night was about at hand. The clanging bell had been calling for half an hour. However, this sort of close to the day's adventures was romantic and therefore satisfactory. When the ferryboat with her wild freight pushed into the stream, nobody cared sixpence for the wasted time but the captain of the craft.

Huck was already upon his watch when the ferry-boat's lights went glinting past the wharf. He heard no noise on board, for the young people were as subdued and still as people usually are who are nearly tired to death. He wondered what boat it was, and why she did not stop at the wharf -- and then he dropped her out of his mind and put his attention upon his business. The night was growing cloudy and dark. Ten o'clock came, and the noise of vehicles ceased, scattered lights began to wink out, all straggling foot-passengers disappeared, the village betook itself to its slumbers and left the small watcher alone with the silence and the ghosts. Eleven o'clock came, and the tavern lights were put out; darkness everywhere, now. Huck waited what seemed a weary long time, but nothing happened. His faith was weakening. Was there any use? Was there really any use? Why not give it up and turn in?

A noise fell upon his ear. He was all attention in an instant. The alley door closed softly. He sprang to the corner of the brick store. The next moment two men brushed by him, and one seemed to have something under his arm. It must be that box! So they were going to remove the treasure. Why call Tom now? It would be absurd -- the men would get away with the box and never be found again. No,
