"In the case of the Hendrickton & Pas Alos there are very steep grades to overcome. Supposedly an electric motor-drive should achieve the same speed on a hill as on the level. But there is the weight of the train to be counted on.

"The H. & P. A. has a two per cent. grade in more than one place. Mr. Bartholomew confessed as much to me last night. The electric-driven locomotive of the powerful freight type, which the Jandel people built for Mr. Bartholomew, can make about sixteen miles an hour on those grades, although they can hit it up to thirty miles an hour on level track.

"His passenger locomotives turn off a mile a minute and more, on the level road; but they can not climb those steep grades at a much livelier pace than the freight engines. That is why he is talking about two-mile-a-minute locomotives. He must get a mighty speedy locomotive, for both freight and passenger service, to keep ahead of Montagne Lewis's rival road, the Hendrickton & Western."

"You don't suppose it can be done, do you?" demanded Ned. "The two-mile-a-minute locomotive, I mean, Tom."

"That is the target I am to aim for," returned his friend, soberly. "At any rate, I hope to improve on the type of locomotive Mr. Bartholomew is now using, so that the hundred thousand dollars bonus will come our way as well as this first twenty-five thousand."

"That wouldn't pay for one engine, would it?" cried Ned.

"Nor is it expected to. The bonus has nothing to do with payment for any model, or patent, or anything of the kind. To tell you the truth, Ned, I understand those big locomotives used by the Chicago, Milwaukee & St. Paul cost them about one hundred and twelve thousand dollars each."

"Whew! Some price, I'll tell the world!" murmured the youthful financial manager of the Swift Construction Company.

When the conference was over, and Tom had been through the workshop to overlook several little jobs that were in process of completion by his trusted mechanics, it was lunch time. He left word that he would not be back that day, for this new task he was to attack was not to be approached with any haphazard thought.

Tom knew quite as well as his father knew that the idea of improving the Jandel patent on electric locomotives was no small thing. The Jandel people had claimed that their patent was the very last word in electric motor-power. And Tom was quite willing to acknowledge that in some ways this claim was true.
