Putting on more power, as they had lagged behind a little, while they were talking, they quickly overtook the car.
"Hey, there," shouted Jack, as they rode up along side, "Give us a couple of your revolvers and we'll try to shoot a hole in their tire."
"Think you can do it?" asked the chief, leaning out of the car.
"Don't know, but we can try it. You'll never catch 'em at this rate and it's the only chance I see."
"All right, here you are," answered the chief, leaning out and handing each of the boys a revolver. "Go get 'em. But you look sharp, now. Those fellows are probably armed and won't hesitate to shoot if they are cornered."
"Yes, boys," joined in Mr. Golden, "don't you get too close to them."
"We'll be careful," replied Bob. "Come on, Jack, now let her out and we'll show them some real speed," and as they turned on the power, they rapidly left the car behind.
But they had lost more ground than they thought, and they rode for fully six miles before catching sight of the robbers, and had begun to fear that they had lost them. But, finally they caught sight of the car about a half mile ahead, and giving the motors a little more current, they rapidly crept up till they were within two hundred yards of them.
Suddenly, they saw the man who was not driving, turn his head, and as he saw them, he said something to his companion, and then, turning in his seat, he drew his revolver.
"He is going to shoot," shouted Jack, and the next instant a shot rang out followed by several others. But, the swaying car made accurate shooting impossible, and he emptied the chamber without doing any harm, although Bob heard one bullet whiz past his head.
