Their youthful, healthy appetites made a feast of the repast. Clark doubled his order, and Ralph did full credit to all the things set before him.

“I was thinking,” he remarked, as they paid their checks at the cashier’s counter, “that we might put in the day looking around the town.”

“Why, yes,” assented his companion approvingly, “that is, if you’re going to let me keep with you.”

“Why not?” smiled Ralph. “You seem to think I may need a guardian.”

“I’ve got nothing to do but put in the time, and get a signed voucher from you that I did so in actual railroad service and in good company,” explained Clark. “I think I will go back to Stanley Junction on your return run, if it can be arranged.”

“It is arranged already, if you say so,” said 49 Ralph. “We seem to get on together pretty well, and I’m glad to have you with me.”

“Now, that’s handsome, Engineer Fairbanks!” replied Clark. “There’s some moving picture shows in town here, open after ten o’clock, and there’s a mechanics’ library with quite a museum of railroad contrivances. We’ve got time to take it all in. Come on. Unless that crowd stops us, we’ll start the merry program rolling. No one in sight,” the youth continued, as they stepped into the street and he glanced its length in both directions. “Have the enemy deserted the field, or are they lying in ambush for us?”

They linked arms and sauntered down the pavement. They had proceeded nearly two squares, when, passing an alley, both halted summarily.

“Hello! here’s business, I guess,” said Clark, and he and Ralph scanned closely the group they had passed just before the breakfast meal.

The hoodlum gang had suddenly appeared from the alleyway, and forming a circle, surrounded them. There was an addition to their ranks. Ralph noted this instantly. He was a rowdy-looking chunk of a fellow, and the swing of his body, the look on his face and the expression in his eyes showed that he delighted in thinking himself a “tough customer.” Backed by his comrades, who looked vicious and expectant, he 50 marched straight up to Ralph, who did not flinch a particle.
