"More trouble!" groaned Tad Butler, wheeling and starting back over the trail at as fast a gallop as possible over the rough ground.

[CHAPTER X]

IN THE HEART OF THE CANEBRAKE

"That boy!" muttered the Professor, as everyone turned sharply and started back, Lilly outdistancing all save Tad, who now rode the jungle fully as well as the guide, except that Tad had never used the bush-knife. It was a dangerous weapon in the hands of an inexperienced rider. With it one was likely to do his horse as well as himself a serious injury.

They heard Chunky's yells for help long before they reached him, and even after reaching a spot where they might have seen the fat boy, they did not at once catch sight of him. They were looking for Chunky on the ground, believing that he had fallen and been left by his horse, while as a matter of fact Stacy was in the air, six or eight feet above the ground.

While standing high in his stirrups he had been caught across the breast by a tough vine that grew between two trees across the trail, so high that the guide's bush-knife had not reached it. Stacy had thrown out both hands to protect himself. The vine had slipped neatly under the lad's arms. The next second he was dangling in the air, with the horse trotting on ahead. And there they found him, swaying back and forth, howling lustily, afraid to let go for fear he would hurt himself when he struck the ground, but almost ready to let go no matter what the consequences might be.

The Pony Rider Boys, when finally they did catch sight of their companion, uttered shouts of merriment.

"Hanged at last!" howled Ned Rector. "Oh, I never thought I should live to see this happy moment!"

Tad brought his horse down just before reaching the fat boy.

"Hello, Chunky, what are you doing up there?" demanded Tad.
