The three performers went through some of their usual exploits, ordinary enough to them, but rather thrilling for all that. Then came the preparations for the new feat.

Joe and Tonzo took their places on the small platforms, high up on the tent poles. The eyes of all in their vicinity were watching them eagerly. Sid was in his place, ready to swing off when the two had crossed each other in the air and had made the exchange.

"Are you ready?" called Jim Tracy in his loud voice.

"Ready," answered Joe's voice, from high up in the tent.

"Ready," responded Tonzo, after a moment's hesitation, during which he pretended to fix one slipper. This was done for dramatic effect, and to heighten the suspense.

Helen, who had just finished her tricks with Rosebud, paused at the edge of a ring to watch the new act.

"Then go!" shouted the ring-master.

Joe and Tonzo swung off together, and then swayed to and fro like giant pendulums, Joe on the rings and Tonzo on the trapeze.

"Ready?" cried Joe to his swinging partner.

"Yes," answered Tonzo.
