At Bob’s words, which although low spoken were intended to reach Jack’s ear, the latter flushed. Then he reached over and pulling Bob’s cap down over his eyes started to shake him good-naturedly. In a moment all three boys were entangled. Mr. Temple laughed and explained the situation to Mr. Harlan. The two men watched the chums amusedly, until a sudden lurch as the train whirled around a sharp curve threatened to send Jack flying overboard.

With a quick movement Mr. Harlan seized Jack by the coat and pulled him back to safety.

“That was a close call,” said Mr. Temple gravely. “You boys ought to be more careful.”

At Oroville, which he explained was in the heart of the apple country, Mr. Harlan left the party. All were sorry to bid him farewell, for he had been a jolly and informative companion. Dinner was served, and the party returned to the club car where Mr. Temple settled down with his cigar and a newspaper. Presently the chums grew tired of reading, and once more sauntered out to the observation platform.

They would not sleep aboard the train again as they would reach their destination near midnight. For a time they gossiped in low voices, so as not to disturb two men whispering together on the other side of the platform. All three sat in silence, slumped

down in their chairs and at first staring out at the landscape bathed in magical moonlight. Gradually Jack and Bob yielded to the soporific influences of their surroundings, with the car wheels beating a monotonous and sleep-inducing lullaby.

Presently the two men who had been whispering raised their voices slightly in argument. Then one ceased abruptly, cast a keen glance toward the boys, said a word or two in a low voice to his companion, and they arose and entered the car. Frank, who like his companions had been sitting with his cap pulled down over his eyes, had not been asleep, however, and as the others left the platform he shook Jack and Bob into wakefulness.

“Did you hear that?” he demanded excitedly.

His two chums rubbed their eyes, and looked puzzled.

“Hear what?” asked Jack.
