CHAPTER XXI
THE PHOTO TELEPHONE
Tom Swift was taking, as he afterward confessed, "a might big chance." But it seemed the only way. He was working against cunning men, and had to be as cunning as they.
True, the man he hoped to capture, through the combination of his photo telephone and the phonograph, might go to some other instrument than one of those Tom had adjusted. But this could not be helped. In all he had put his new attachment on eight 'phones in the vicinity of the sawmill. So he had eight chances in his favor, and as many against him as there were other telephones in use.
"It's a mighty small margin in our favor," sighed Tom.
"It sure is," agreed Ned. They were at Mrs. Damon's house, waiting for the call to come in.
"But we couldn't do anything else," went on Tom.
