So have I," said Dick.

"And I," said the Senator, "am sorry to say that I have nothing at
all."

"Well, I suppose we must go," said the Doctor. "My revolver is
something. It is a double revolver, of peculiar shape."

Without any other thought they at once prepared to venture into a
district that for all they knew might swarm with robbers. They had
only one thought, and that was to save Figgs.

"Can this man lead us?" asked Dick.

"He says he can take us along where he saw Figgs go, and perhaps we
may see some people who can tell us about him."

"Perhaps we can," said the Senator, grimly.

They then started off with the Italian at their head. The sun was by
this time within an hour's distance from the horizon, and they had no
time to lose. So they walked rapidly. Soon they entered among hills
and rocks of lava, where the desolation of the surrounding country
began to be modified by vegetation. It was quite difficult to keep
their reckoning, so as to know in what direction they were going, but
they kept on nevertheless.

All of them knew that the errand was a dangerous one. All of them knew
that it would be better if they were armed. But no one said any thing
of the kind. In fact, they felt such confidence in their own pluck and
resolution that they had no doubt of success.

At length they came to a place where trees were on each side of the
rough path. At an opening here three men stood. Buttons at once
accosted them and told his errand. They looked at the Americans
with a sinister smile.

"Don't be afraid of us," said Buttons, quietly. "We're armed with
revolvers, but we won't hurt you. Just show us where our friend is,
for we're afraid he has lost his way."

At this strange salutation the Italians looked puzzled. They looked
at their guns, and then at the Americans. Two or three other men
came out from the woods at the same time, and stood in their rear.
At length as many as ten men stood around them.

"What are you staring at?" said Buttons again. "You needn't look so
frightened. Americans only use their revolvers against thieves."

The Doctor at this, apparently by accident, took out his revolver.
Standing a little on one side, he fired at a large crow on the top
of a tree. The bird fell dead. He then fired five other shots just
by way of amusement, laughing all the time with the Senator.

"You see," said he--"ha, ha--we're in a fix--ha, ha--and I want to
show them what a revolver is?"

"But you'
