The Widow Douglas' splendid hospitality was a tempting bait. It and Tom's persuasions presently carried the day. So it was decided to say nothing to anybody about the night's programme. Presently it occurred to Tom that maybe Huck might come this very night and give the signal. The thought took a deal of the spirit out of his anticipations. Still he could not bear to give up the fun at Widow Douglas'. And why should he give it up, he reasoned--the signal did not come the night before, so why should it be any more likely to come tonight? The sure fun of the evening outweighed the uncertain treasure; and, boy-like, he determined to yield to the stronger inclination and not allow himself to think of the box of money another time that day.

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 icehouse, 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.
