hich 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 ferryboat 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."

The boys still listened and watched. Presently a revealing thought
flashed throug
