“Is there a car following us?” exclaimed Bob, swallowing the last bite of his sandwich.
“Yes, and has been for the last half hour,” went on Ned. “I don’t believe it’s just a coincidence.”
“Take a look with the glasses,” suggested Jerry, nodding toward a side pocket in the auto—a pocket where a pair of powerful field glasses were carried. Ned adjusted them to his eyes and, standing up while Jerry slowed down, looked back. He gazed for a moment and then cried:
“It’s them!”
“Who?” demanded Bob and Jerry. Professor Snodgrass was taking but little interest in what was going on, as he was busy reading a book on South American beetles. Bill Cromley, though, was all attention.
“Some one on our trail?” demanded the old miner. “Who is it?”
“Noddy Nixon and Jack Pender!” declared Ned. “Take a look!”
He handed the glasses to Jerry, who had stopped the car.
“It’s Noddy all right,” the tall lad said quietly. “And I believe he is trying to follow us.”
