"That must be them," said Bob in a low voice. "Now what'd we better do?"

"We'll hide in the bushes on each side of the road," proposed Mr. Switzer, "and when they come along, we'll jump out and stop 'em. You all got guns?"

It turned out that only the policemen had revolvers, so the chief, Mr. Golden and Uncle Ben hid on one side of the woods road, while the other two policemen and the boys concealed themselves on the other.

"Now," whispered the chief, "don't make a sound till I tell 'em to stop, then you cover 'em with your guns and if they try to get away, let 'em have it, but don't shoot to kill if you can help it 'cause we want to get those fellows alive if we can."

Nothing more was said and in a few minutes the car was near at hand, as they could tell by the sound, and, peering through the bushes, Bob spied a large car coming slowly along the road. Two men were on the front seat.

"I believe that's King driving," whispered Bob, "though he's shaved off his beard."

At that instant, Chief Switzer sprang out into the middle of the road in front of the car, closely followed by Mr. Golden and Uncle Ben, while the other policemen and the boys followed suit from their side.

"Halt, in the name of the law," shouted the chief, flourishing his revolver.

The car was about ten feet from them as the order was given, and instead of obeying, the driver suddenly put on high speed and the car shot toward them. So quickly was it done that they had barely time to save themselves from being run down by jumping to one side as the car shot by and turned into the main road heading toward Oakland.

"Gosh, they'll get away sure as thunder," shouted Switzer, as he fired his revolver after the vanishing car. "Come on, we've got to chase them."
