"Well, I thought it best to mention it," said Joe.

He was now ready for his most novel form of walking the wire. He moved toward the window from which the woman had leaned. It was the same casement whence the cat had started on its perilous journey. Joe felt sure of himself. The slippers were just what he needed, with soft, pliable soles, worn thin. They were the best substitute he could have found for his circus shoes.

The wire from which the banner was suspended was fast to an eye-bolt set in the brick wall of the building a little below the sill of the window. It had been easy for the cat to step out and get on the cable.

Joe appeared at the window. He had taken off his coat and, in his white shirt, blue tie, and black trousers, he made a striking figure in the brilliant sunset light.

Instantly the crowd in the street saw him and divined his intention. Joe doubted not that Helen was looking up at him.

It was an easy step for him from the window sill to the wire from which was suspended the banner. He knew it would support his weight in addition to the big net affair. The size of the cable and the manner in which it was fastened told him that. Still he cautiously tried it with one foot before trusting all his weight to it. The spring of the wire told him all he needed to know.

Pausing a moment to make sure of himself, Joe Strong started to walk across the wire toward the clinging cat. The crowd gave one roar of welcome and approval, and then became hushed. This was what Joe wanted.

Now it was just as if he were doing the act in the circus. Only there was this difference—there was no safety net below him. But it was not the first time Joe had taken this risk. True, beneath him were the hard stones of the street, but a fall from the height at which he now was would be fatal, no matter what the character of ground under him. He dismissed all such thoughts from his mind.

Slowly, and with the caution he always used, Joe started on his journey across the wire. The cat felt his coming, and turned its head, as it crouched down, and looked at him. But it did not move. The creature was literally "scared stiff."

Foot by foot Joe progressed. Below him the crowd watched breathlessly. Joe knew Helen was there, praying for him, though he could not see her. In the window stood the figure in black, a silent, hopeful but much worried woman. She kept her promise not to scream, but Joe realized that the crucial moment was yet to come.
