To the right the well-known Chilkoot Pass extended up into the mountain fastness, the pass that had been traveled by so many in the early rush for the gold fields. Chilkoot a long distance to the northeast intersects the White Horse Pass. It is a rugged trail, but an easier one to travel than the one chosen by the Pony Rider Boys for the first stage of their journeyings.

The object of Professor Zepplin in choosing the route to the northwest was to take the boys into territory that had been little explored, and to give them their fill of what is really the wildest and most rugged region of the United States.

“By the way,” called Rector after they had gotten well started and had dropped the village behind them, “what became of our friends?”

“The four gold diggers?” asked Butler.

“They must have gone on with the ship,” said Walter.

“Yes, they must have,” agreed Stacy.

“Did you let him?” questioned Chunky.

“Yes. Why should I wish to force myself on anyone who doesn’t want to see me? Not I. They are queer fellows. It isn’t because they don’t like us, but rather because they are suspicious. They are afraid someone will get a line on where they are going. Wouldn’t it be queer if we were to bump into them somewhere in the interior?”

“No danger of that,” spoke up the Professor. “I heard Mr. Darwood say they were going out the Chilkoot Pass for a short distance, from which they might branch off.”
