"No go!" he hurriedly whispered. "There's a door in the end. Make for the pilot. Quick! Quick!"

Expedition was necessary, for the air breaks had released their grip upon the wheels, and the train was again assuming speed.

Tom rushed in front of the locomotive and with a spring and a scramble, safely seated himself on the platform immediately above and in the rear of the pilot; or, as it is better known in schoolboy nomenclature, the "cow-catcher."

Ben was not so fortunate. With a scantier knowledge of their construction and the art of boarding them, his foot slipped from the inclined grating and struck the fast retreating rail beneath. Another instant and he would have been drawn down to death, had not Tommy's hand grasped his collar and aided him up.

"Thank you, Tommy," he said warmly, "I owe you one."

"You may be able to pay me sometime. Aint this old peaches!" And Tommy gazed on the great broad pathway of light in front, made by the Cyclopean eye over head.

The novelty of his new position was exhilarating to Ben. There was a spice of danger about it, that made it enchanting.

What if the locomotive should jump the track! Or should be ditched! Or run into another train! Or strike some stray animal! It rocked and swayed to and fro like a ship at sea. He could hardly satisfy himself that this rattling, rickety, rocking, jumping, sliding, groaning iron horse was the same metallic animal that pulled those easy riding, luxurious coaches he had so often rode in. It appeared to him—novice in locomotive riding as he was—that every moment the steel-shod steed was about to leave the track and take to the fields. Singular too, it was neither cold nor windy; for nestling close against the iron boiler head both felt quite comfortable.

"Tommy," said Ben, "suppose we should catch up a horse?"

"Then we'd be a horse ahead," replied Tom. "I met a tramp who had taken a ride on a cow-catcher on the New York Central. He was bound for Buffalo. Well sir, they caught up a big pig, and landed it all unhurt, but terribly scared, right into the tramp's lap. He hung on to it, and when he got the bounce, he took the pig with him and sold it for enough to pay his fare to Buffalo."
