"Of course I can," and the young reporter spoke confidently.

The car was stopped and the change made. Larry soon found he could manage the various levers all right, and that the car responded readily to his guiding hand.

"This must be the place," he said, after they had ridden for half an hour at as high speed as they dared, considering the fact that there were policemen on every other block.

He stopped the car in front of a house that seemed to be uninhabited. It answered the description Retto had given, and Larry knocked on the door. After several minutes the portal opened a crack, showing that it was held by a chain.

"Is Mr. Potter here?" asked Larry, though he knew the missing millionaire was not. The man who had opened the door looked suspiciously at the inquirer. "It's all right," the young reporter went on. "I come from Mr. Retto. I want to aid Mr. Potter."

"You're too late," was the answer. "They've got him into their clutches. They'll work their game before he knows that everything is all right, and that it is safe for him to show himself. If they had only waited half an hour all would have been well. I just got another telephone message from Retto, saying that all matters were satisfactorily adjusted, and that there was no further need for Mr.

Potter to hide. But he doesn't know this. I have no way of telling him, and he'll sign the papers before those men will let him go."

"Tell me in which direction they went and I'll go after them!" cried Larry. "They can't have gone far, and we can overtake them in the auto!"

"They have a car, too," replied the man. "A fast one. They managed, by a trick, to get Mr. Potter into it. If I could only get word to him he could laugh at their efforts! If I could only send him a message!"

"What is the message?" asked Larry.

"It is this. 'The money is safe!'"

"Is that all?"

"That's all, but how can you get it to him?"

"Didn't you hear anything that might give you a clue to where the men were going?"

"Somewhere out toward the Orange Mountains. That's all I know. They are going to the home of some lawyer or judge, I believe. There is some legal matter involved."

"Then that's where we'll go!" decided the young reporter, as he hurried back to the auto and told Grace and Fritsch what he had heard.

"On to de mountains!" cried the German reporter. "My car is yours!

It will climb de biggest hills on der high gear, und ve will catch de scoundrels!"

Once more they were off. They took the Plank Road to Newark, and, on inquiring in the latter city, learned that a car, answering the description of the one Mr. Potter had been taken off in, had pa.s.sed about half an hour before.

"That's not so bad!" exclaimed Larry. "We can catch 'em, I guess!"

"I hope so!" murmured Grace.

"If my car doesn't beat de oder one I gives up riding," remarked Fritsch, with proper pride in his machine.

They pa.s.sed through Newark, and were soon on the road leading to Orange, at the foot of the mountains. The highway was conducive to speed, and Larry "let her out several notches," as he expressed it, at the same time keeping watch for policemen on motorcycles, who were alert to nab the unwary auto speeders.

Every time they saw a car in front of them they were anxious until they saw it was not the one they wanted. They pa.s.sed a number of machines, and when Orange was reached they had not been successful.

"Now for a mountain climb!" exclaimed Larry, as he slowed down the engine to give the water a chance to cool off before attempting the ascent. "Will it do Eagle Rock hill, Fritsch?"

"I think so," replied the German. "I never tried it, but de circular says it vill do it."

Eagle Rock hill is known far and wide as one of the steepest ascents up which an automobile can be sent. Many cars have to take it on the low gear, or go as slowly as possible. Even then it is a strain.

"Suppose we should overtake them there?" suggested Grace.

"Ve'd catch 'em!" exclaimed the German, with a confidence born of admiration for his car.

On and on they chugged. At the foot of the long, steep slope Larry set the levers on second gear, as he did not want to take any chances with the auto. Up and up they went, their eyes strained through the dust for the sight of a green car, for that was the color of the machine in which rode the men who had taken Mr. Potter away.

"Hark!" exclaimed Grace, suddenly. "It sounds like an auto just ahead of us!"

"It is," declared Larry, whose quick ear had caught the chug-chug of a motor.

An instant later they had rounded a turn. There, in front of them, climbing the steep hill, was a green car. In it could be seen four men.

"That's them!" cried Larry.

"Open her up! Throw in the high gear!" yelled Fritsch, who was now as enthusiastic and as interested in the chase as were either of his companions. "Let her rip!"

"Will she stand it?" asked Larry, shouting the words over his shoulder to Grace and Fritsch in the tonneau.

"Sure!"

There was a grinding noise as Larry threw in the high-speed gear.

The auto hung back for an instant because of the sudden change. The motor seemed to groan at the unexpected load thrown on it. Then, like a gallant horse responding to the call of its rider, the car leaped ahead.

"Hurrah!" cried Larry. "She'll do it! We'll catch 'em!"

The distance between the two cars was lessening. Those in the green machine seemed unaware of the approach of their pursuers.

"Can you see your father?" asked the German of Grace.

"I'm not sure. It looks like him!"

She stood up in the tonneau, holding to the back of the seat in front of her to steady herself against the swaying of the car.

Just then Larry blew a blast on the horn. As the deep tone responded to his pressure on the big rubber bulb the men in the green machine looked back. At the sight of one of the faces Grace cried.

"It's father! It's father!"

Above the noise made by the two autos the millionaire heard his daughter's voice. He stood up and, leaning over the back of the seat, waved his hand to her. Then one of the men sitting beside him forcibly drew the millionaire down.

"Oh! We must get to him!" cried Grace. "They may do him some harm!

Hurry, Larry!"

"Shove her over a few more notches!" cried Fritsch. "She'll take more gasolene!"

Larry obeyed the instructions of the German reporter. The car seemed to feel new life and leaped ahead. The distance from the other car was steadily growing less. Fritsch's confidence in his machine was not misplaced. But the men in the green car were making efforts to escape. The chauffeur had advanced his spark, and the car was taking the steep grade almost as well as was that of the pursuers.

"Can't we catch them?" cried Grace, in an agony of doubt and fear.
