"Now you've done it! I'll give you a good thrashing when I get back!" roared Gus, shaking his fist at Joe, who stood staring, half-pleased, half-scared, at what he had done.

"Are you really going to try it?" asked Gus, as they glided on with increasing speed, and he, too, felt the charm of such a novel adventure, though the consequences bid fair to be serious.

"Yes, I am," answered Frank, with the grim look he always wore when his strong will got the upper hand. "Bill will give it to us, any way, so we may as well have our fun out. If you are afraid, I'll slow down and you can jump off," and his brown eyes sparkled with the double delight of getting his heart's desire and astonishing his friend at the same time by his skill and coolness.

"Go ahead. I'll jump when you do;" and Gus calmly sat down again, bound in honor to stand by his mate till the smash came, though rather dismayed at the audacity of the prank.

"Don't you call this just splendid?" exclaimed Frank, as they rolled along over the crossing, past the bridge, toward the curve, a mile from the station.

"Not bad. They are yelling like mad after us. Better go back, if you can," said Gus, who was anxiously peering out, and, in spite of his efforts to seem at ease, not enjoying the trip a particle.

"Let them yell. I started to go to the curve, and I'll do it if it costs me a hundred dollars. No danger; there's no train under twenty minutes, I tell you," and Frank pulled out his watch. But the sun was in his eyes, and he did not see clearly, or he would have discovered that it was later than he thought.

On they went, and were just rounding the bend when a shrill whistle in front startled both boys, and drove the color out of their cheeks.

"It's the factory train!" cried Gus, in a husky tone, as he sprang to his feet.

"No; it's the five-forty on the other road," answered Frank, with a queer thrill all through him at the thought of what might happen if it was not. Both looked straight ahead as the last tree glided by, and the long track lay before them, with the freight train slowly coming down. For an instant, the boys stood as if paralyzed.

"Jump!" said Gus, looking at the steep bank on one side and the river on the other, undecided which to try.

"Sit still!" commanded Frank, collecting his wits, as he gave a warning whistle to retard the on-coming train, while he reversed the engine and went back faster than he came.

A crowd of angry men was waiting for them, and Bill stood at the open switch in a towering passion as No. 11 returned to her place unharmed, but bearing two pale and frightened boys, who stepped slowly and silently down, without a word to say for themselves, while the freight train rumbled by on the main track.
