Faster and faster the plane pushed its way through the air and nearer and nearer they drew to their quarry.
So far as Jack could see the distant aviator never swerved from his course which was south-westerly.
“I’ll bet he’s planning to hit either Boston or New York,” he thought.
It was soon evident that they were rapidly overhauling the other flyer and before long Jack could easily make out the form of the driver with the aid of the glass. Just then Captain Brice turned in his seat.
“I’m going to slow her down a bit,” he shouted.
As he spoke Jack keeping his eyes on the plane ahead now not more that an eighth of a mile away, saw the man turn his head.
“He’s seen us,” he shouted.
The fact was at once evident for, as their machine slowed up the other began to draw away. Seeing this Captain Brice at once increased his speed but to his amazement he was no longer able to decrease the distance between the two planes.
“He’s got some speed there,” he shouted back as he gave his plane the last notch.
And now Jack saw that the machine ahead was changing its course. In a large arc he swung until in the course of fifteen or twenty minutes he was heading back nearly due north.
