"What's the use, Tom? We'll get to Mardean before we can cross the line, anyhow. I'll go fast enough then for a spell, if you're anxious for speed. Don't be impatient! We'll get all the speed you want before very long."

Jack was a true prophet, as one ought to be when he has the means of fulfilling the prophecy in his own hands. At Mardean, just out of sight of the line, they waited while the minutes dragged slowly by.

"One minute more!" cried Tom Binns, breathless with excitement and suspense.

"All right," said Jack, quietly. "Hold tight now, Tom! I'm going to let her out a bit."

Swiftly the grey car gathered speed. In a rush of dust, with horn blowing and exhaust sputtering behind them, the car shot over the line, and, just as a whistle boomed out the twelve o'clock dinner signal, Jack was in hostile territory. The war was on!

Behind them there was a confused shouting. The car was built so that it was easy to look behind.

"There was an outpost there," said Tom, as he looked back. "They're kicking up a tremendous fuss, Jack. I guess we rather put one over on them that time."

"We've got to put another one over on them in a hurry, then," said Jack, "or they'll put one over on us. Let me know as soon as that outpost is well out of sight, Tom. And keep your eyes skinned for any sign that they're after us with a motorcycle or anything like that, will you?"

"They're out of sight now—and there's nothing on the road. Hey, Jack, where are you going?"

For Jack, after a swift glance at his map, had run deliberately off the road, reducing speed considerably as he did so, but not so much that the car did not rattle around considerably as it left the smooth roadbed and plunged into a field that had not long since been ploughed.
