"Hurrah! here's a discovery!" cried Bob. "Shall we go on?"
"Yes; but let us advance with extreme caution. These Svlachkys may be
very bad people."
"Undoubtedly there are, or they wouldn't keep my father a prisoner,"
rejoined Bob.
"That signpost must be the work of Ruel Gross," went on the captain.
"The savages haven't dared to touch it, thinking there was something
supernatural attached to it--something to injure them."
On went the captain and Bob, down one hill of ice and up another. It was
extremely cold, but neither minded that.
At last they reached a portion of the island that was very uneven. Great
chasms yawned to the right and left of them. It was with difficulty that
they pushed forward.
But they were bound to go on, and go they did, until at the mouth of
what looked like a cave of ice the captain called a halt.
They waited. Presently the three men disappeared within the opening.
Soon a smoke came out, and they saw that firebrands had been lit to
light up the scene.
"That may be the place where the stone chest is kept," said Bob.
"More likely it is a burial place," replied Captain Sumner. "I've seen
such spots before. Maybe they're preparing for a funeral."
