"But where is Tom?" came from Sam.

"He must be right ahead of us—if what we have been told is true," answered his brother.

The conversation recorded above took place just ten days after Dick and Sam arrived in Dawson City. During that time the Rover boys and Jack Wumble had spent two days in buying the necessary outfit, to follow Tom and his strange companion to the wild region in Alaska known as Lion Head. The start had been made, and now the three found themselves on a narrow mountain trail in a country that looked to be utterly uninhabited.

For three days they had been close behind Tom and Ike Furner, this being proven by the remains of campfires and other indications. Once they had met some prospectors returning to the Klondyke and these men had told of passing the pair ahead, and that Furner had said they were bound for a spot not many miles from Lion Head called Twin Rocks.

"I never heard o' Twin Rocks before," said Jack Wumble. "But if it is nigh Lion Head we ought to be able to locate it."

"Provided we don't get snowed in before we reach it," returned Sam.

On and on trudged the three. They had left the last supply depot behind. They had passed only a handful of white folks and a band of five Indians.

"Do you know, I didn't like the looks of those Indians we passed yesterday," remarked Dick, as they went forward over the rough, upward trail.

"They looked pretty sharply at our outfits," said Sam. "I guess they'll like to own them," he added.

"We have got to keep our eyes open," said Jack Wumble. "Them Injuns ain't above stealin' if they git a chanct."
