From the landing they proceeded by hand-car to Cascade Junction, where they boarded a west-bound passenger train over the Northern Pacific. Even now Mr. Linton was not communicative, and after sitting awhile in silence he went forward into the smoking-car, leaving the boys in the passenger coach next behind it. Now they began to discuss their situation, and the more they considered it the more apprehensive they became that something unpleasant was in store for them.

"He's a United States marshal, remember," said Bonny.

"Yes," replied Alaric; "I've been thinking of that. Do you suppose it can have anything to do with that smuggling business?"

"I'm awfully afraid so," replied Bonny. "Great Scott! Look there!"

The train was just leaving Meeker, where a passenger had boarded their car, and was now walking leisurely through it towards the smoker. It was he who had attracted Bonny's attention, and at whom he now pointed a trembling finger.

Alaric instantly recognized the man as an officer of the revenue-cutter that had so persistently chased them in the early summer. Without a word, he left his seat and followed the new-comer to the smoking-car, where a single glance through the open door confirmed his worst suspicions.

The officer had seated himself beside Mr. Linton, and they were talking with great earnestness.

"They are surely after us again," Alaric said, in a whisper, as he regained his seat beside Bonny; "but I don't intend to be captured if I can help it."

"Same here," replied Bonny.

Thus it happened that when, a little later, the train reached Tacoma, and Mr. Linton returned to look for his lads, they were nowhere to be found.
