When it came they had need for it, for the jungle growth now was thicker. Heavy creepers and vines had appeared among the elder bushes, their phenomenal growth often matted thickly together as high as a man's waist. Bushes which formerly had given way at the thrust of a shoulder now hung toughly, suspended by the inextricable grip of the vines. Along the ground the matted creepers caught and clung tenaciously to ankles. The carpet of them hid with fair leaves and blossoms treacherous water holes into which the travelers plunged at times foot deep. In one such a plunge Payne's boots sent squirming a nest of slimy water moccasins. A moment later he slipped and all but fell on the hard slippery back of a hidden turtle. A gleam of light in the solid growth ahead promised an open space for a rest and breathing spell. With a silent agreement they plunged straight for it. As they wedged their way into sight a flock of black buzzards rose lazily from something upon the ground, their wings barely lifting their gorged bodies, their foul red heads reeking with the putrid feast they were so loath to leave. Higgins voiced his disgust in one swift curse, but Payne bored silently on in a wide circuit round the stench. A broken trail in the jungle soon told the story. The tracks of a single steer were discernible, pointing toward the opening, and there were no tracks returning. The animal, lost in the thicket had fought its way out till, in the open space, its strength gone, it had collapsed. Payne stopped at the animal's tracks. "That steer came in from the west. It couldn't have come very far through this jam, so probably that cattle prairie isn't very far out that way. We could go out there. I suppose some of Garman's men would see us if we did. I don't like to have him know where we're bound for." Higgins was silent. "Well?" The engineer's reply was to crash into the thicket, breaking the way; and Payne followed without more words. At noon they dropped on a bed of vines which fairly smothered the brush, and ate sparingly of the venison they had brought; cautiously they dipped water from a deep root hole and barely wet their lips. "Have we made four miles?" asked Higgins. "Just about--less than a mile an hour. Better start again before we begin to stiffen."
