They found plenty of things to be delighted with, but nothing to be astonished at. They discovered that the island was about three miles long and a quarter of a mile wide, and that the shore it lay closest to was only separated from it by a narrow channel hardly two hundred yards wide. They took a swim about every hour, so it was close upon the middle of the afternoon when they got back to camp. They were too hungry to stop to fish, but they fared sumptuously upon cold ham, and then threw themselves down in the shade to talk. But the talk soon began to drag, and then died. The stillness, the solemnity that brooded in the woods, and the sense of loneliness, began to tell upon the spirits of the boys. They fell to thinking. A sort of undefined longing crept upon them. This took dim shape, presently--it was budding homesickness. Even Finn the Red-Handed was dreaming of his doorsteps and empty hogsheads. But they were all ashamed of their weakness, and none was brave enough to speak his thought.

For some time, now, the boys had been dully conscious of a peculiar sound in the distance, just as one sometimes is of the ticking of a clock which he takes no distinct note of. But now this mysterious sound became more pronounced, and forced a recognition. The boys started, glanced at each other, and then each assumed a listening attitude. There was a long silence, profound and unbroken; then a deep, sullen boom came floating down out of the distance.

"What is it!" exclaimed Joe, under his breath.

"I wonder," said Tom in a whisper.

"'Tain't thunder," said Huckleberry, in an awed tone, "becuz thunder--"

"Hark!" said Tom. "Listen--don't talk."

They waited a time that seemed an age, and then the same muffled boom troubled the solemn hush.

"Let's go and see."

They sprang to their feet and hurried to the shore toward the town. They parted the bushes on the bank and peered out over the water. The little steam ferry-boat was about a mile below the village, drifting with the current. Her broad deck seemed crowded with people. There were a great many skiffs rowing about or floating with the stream in the neighborhood of the ferryboat, but the boys could not determine what the men in them were doing. Presently a great jet of white smoke burst from the ferryboat's side, and as it expanded and rose in a lazy cloud, that same dull throb of sound was borne to the listeners again.

"I know now!" exclaimed Tom; "somebody's drownded!"

"That's it!" said Huck; "they done that last summer, when Bill Turner got drownded; they shoot a cannon over the water, and that makes him come up to the top. Yes, and they take loaves of bread and put quicksilver in 'em and set 'em afloat, and wherever there's anybody that's drownded, they'll float right there and stop."

"Yes, I've heard about that," said Joe. "I wonder what makes the bread do that."

"Oh, it ain't the bread, so much," said Tom; "I reckon it's mostly what they _say_ over it before they start it out."

"But they don't say anything over it," said Huck. "I've seen 'em and they don't."

"Well, that's funny," said Tom. "But maybe they say it to themselves. Of _course_ they do. Anybody might know that."

The other boys agreed that there was reason in what Tom said, because an ignorant lump of bread, uninstructed by an incantation, could not be expected to act very intelligently when set upon an errand of such gravity.

"By jings, I wish I was over there, now," said Joe.

"I do too" said Huck "I'd give heaps to know who it is."
