He was struck dumb with amazement when, for the first time in his life, he saw a locomotive gliding along the rails, with a glaring headlight and a cloud of flying sparks. Once, when it was motionless on the track, they talked to the engineer, who explained "the workings of the critter," as Ike called it.

The boy understood so readily that the engineer said, after a time, "You're a likely feller, for such a derned ignoramus! Where have you been hid out, all this time?"

"Way down in Pore Valley," said Ike very humbly.

"He's concluded to be a great inventor," said one of his young friends, with a merry wink.

"He's a mighty artificer in iron," said the wit who had named him Tubal-cain.

The engineer looked gravely at Ike. "Why, boy," he admonished him, "the world has got a hundred years the start of you!"

"I kin ketch up," Ike declared sturdily.

"There's something in grit, I reckon," said the engineer. Then his wonderful locomotive glided away, leaving Ike staring after it in silent ecstasy, and his companions dying with laughter.

He started out to overtake the world at a night-school, where his mental quickness contrasted oddly with his slow, stolid demeanor. He worked hard at the forge all day; but everybody was kind.

Outside of Poor Valley life seemed joyous and hopeful; progress and activity were on every hand; and the time he spent here was the happiest he had ever known,—except for the recollection of that frightened, beseeching face which had looked out after him through the closing mists.
