“And whose fault was it?” Mr. Oaks interrupted angrily. “I helped you and that girl friend of yours, didn’t I? Well, now it’s your turn to do me a little favor, ’specially since it wasn’t my fault I lost the bridge job.”

“I’ll talk to Dad,” Penny said. Annoyed by the watchman’s attitude, she did not prolong the interview, but quickly climbed down from the barge.

From the coal yards she followed the river for a distance, coming presently to more pleasant surroundings. She was still thinking about Carl Oaks as she approached the Ottman boathouse. Sara and a young man were deeply engrossed in examining a large metal object which appeared to be a homemade diving hood.

For a moment Penny assumed that Sara’s companion was Bill Evans. However, as the young man turned slightly, she saw his face.

“Why, it’s Burt Ottman!” she thought. “He’s back on his old job after being released from jail. I’m going to talk to him and see what he’ll say!”

SALVAGE AND SABOTEURS

Sara Ottman and her brother glanced up from their work as Penny approached the dock. Burt was a tall young man of twenty-six, brown of face, with muscles hardened by heavy, outdoor work. He nodded to Penny, but his expression did not disclose whether or not he bore resentment.

“Anything we can do for you?” he asked, his manner impersonal.

“No, I just happened to be over this way and thought I’d stop for a minute. What’s this strange contraption?” Penny indicated the queer looking metal hood.

“A diving apparatus Burt made,” Sara explained briefly. “We’re using it to get Bill Evans’ motor out of the river.”
