“I want to get to Mowern Junction before the four-twenty train from here goes on to Abbeylands. Can I do it?” said Harold.

“Next train to the Junction five-thirty-two, sir,” said the official.

“That’s too late for me,” said Harold. “The train leaves the Junction for Abbeylands a quarter of an hour after arriving at Mowern. Is there no local train that I might manage to catch that would bring me to the Junction?”

“None that would serve your purpose, sir.”

Harold clearly saw how it was that this company could never get their dividend over four per cent.

“Why is there so long a wait at Mowern?” he asked.

“Waits for Ditchford Mail, sir.”

“And at what time does a train start for Ditch-ford?”

“Can’t tell, sir. Ditchford is on the Nethershire system—they have running powers over our line to Mowern.”

Harold whipped out his guide, and found Ditch-ford in the index. By an inspiration he turned at once to the page devoted to the Nethershire service of trains. He found that, by an exquisite system of timing the trains, it was possible to reach a station a mile from Ditchford on the one line, just six minutes after the departure of the last local train to Ditchford on the other line. It took a little ingenuity, no doubt, on the part of the Directors of both lines to accomplish this, but still they managed to do it.
