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 ferryboat'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, he would stick to their wake and follow them; he would trust to the darkness for security from discovery. So communing with himself, Huck stepped out and glided along behind the men, cat-like, with bare feet, allowing them to keep just far enough ahead not to be invisible.
