"Oh, we didn't go into this to fail," cheerily responded the youth by his side. "If we 'fall down' it won't be on a simple thing like this. He'll be here. It won't take us but three minutes to transfer the stuff when it gets here. Never fear. I'll just take another look in the car to make sure."

As he did so the colored boy exclaimed:

"It's all right. Here's de screws as he done tole us to git and here's de screw-driver outen de box as he done writ us to have ready and dar's de door all ready fur to fly open."

To prove it the lad gave the wide door in the side of the car a shove, and as it ran back on its track a portion of the inside of the car was exposed. It was a peculiar car and worth description, for in it, next to the big engine and ahead of all the other cars of the almost endless train, Ned Napier, his friend Alan Hope, and their servant, Elmer Grissom, were to be the sole passengers on a most mysterious and, as it proved, most eventful journey. In railroad parlance the car was what is known as a "club" car. Half of the interior was bare and unfinished, like the compartment in which, on special and limited trains, baggage is carried. This part of the car, now exposed to view, was dimly lighted with one incandescent bulb. In the half-light it could be seen that the space was almost wholly filled with tanks, boxes, casks, crates and bundles, all systematically braced to prevent jarring or smashing. It was plainly not the luggage of ordinary travelers. Except for a narrow passageway in the center of the car and a space about five square next the open door, every inch, to the very ventilators of the car, was crowded with bound or crated, numbered and tagged packages. In the open space next the door Alan Hope now appeared.

"Coming yet?" he asked with apparent confidence as he peered outside.

The colored boy Elmer shook his head.

Just then the conductor returned and again his watch.

"Eight minutes," he said; "time's getting along and I've got to go back and see about my train. I don't want to make you nervous, but do you want us to take this car if fails to get here with the stuff?"

"I suppose there's no need," replied the military man, beginning to show irritation. "But there's eight minutes yet."

"I know," replied the conductor, "but after we are coupled up and it is time to leave we can't stop to cut this car out. We've got to have five minutes for that. At five minutes of eight you'll have to decide whether it is go or stay. I'm sorry—but you'll have to decide in a minute or two."
