n his jacket pocket, and the other he put in Joe's hat and
removed it to a little distance from the owner. And he also put into the
hat certain schoolboy treasures of almost inestimable value--among them
a lump of chalk, an India-rubber ball, three fishhooks, and one of that
kind of marbles known as a "sure 'nough crystal." Then he tiptoed his
way cautiously among the trees till he felt that he was out of hearing,
and straightway broke into a keen run in the direction of the sandbar.

CHAPTER XV

A FEW minutes later Tom was in the shoal water of the bar, wading
toward the Illinois shore. Before the depth reached his middle he was
half-way over; the current would permit no more wading, now, so he
struck out confidently to swim the remaining hundred yards. He swam
quartering upstream, but still was swept downward rather faster than he
had expected. However, he reached the shore finally, and drifted along
till he found a low place and drew himself out. He put his hand on his
jacket pocket, found his piece of bark safe, and then struck through
the woods, following the shore, with streaming garments. Shortly before
ten o'clock he came out into an open place opposite the village, and
saw the ferryboat lying in the shadow of the trees and the high bank.
Everything was quiet under the blinking stars. He crept down the bank,
watching with all his eyes, slipped into the water, swam three or four
strokes and climbed into the skiff that did "yawl" duty at the boat's
stern. He laid himself down under the thwarts and waited, panting.

Presently the cracked bell tapped and a voice gave the order to "cast
off." A minute or two later the skiff's head was standing high up,
against the boat's swell, and the voyage was begun. Tom felt happy in
his success, for he knew it was the boat's last trip for the night. At
the end of a long twelve or fifteen minutes the wheels stopped, and Tom
slipped overboard and swam ashore in the dusk, landing fifty yards
downstream, out of danger of possible stragglers.

He flew along unfrequented alleys, and shortly found himself at his
aunt's back fence. He climbed over, approached the "ell," and looked in
at the sitting-room window, for a light was burning there. There sat
Aunt Polly, Sid, Mary, and Joe Harper's mother, grouped together,
talking. They were by the bed, and the bed was between them and the
door. Tom went to the door and began to softly lift the latch; then he
pressed gently and the door
