“Well, I daresay they will bring my patient again to-morrow morning, and we will wait till then, and afterwards I should propose that we journey on at once.”

“But you said you were going to ask Mak again about where the big stones are,” said Mark, and he signed to the black, who was standing leaning upon his spear watching them, and now in response to the boy’s signal, came up at once.

“You ask him, my boy,” said the doctor, who was carefully examining the contents of his knapsack and tightening the cork of the little bottle before rolling it up again in the lint and bandages.

Mark seized the opportunity.

“Here, Mak,” he cried, “big stones? Where?”

The black turned at once and pointed with his spear in the direction of the forest.

“There, I told you so!” said Mark. Then to the black, “Well, go on; show the way.”

Mak, who evidently understood, swung himself half round, and now pointed right along to the edge of the forest.

“That’s clear enough, Mark,” said the doctor. “He means we have to go round, keeping to the edge and along the open plain where the bullocks can trek.”

“Buck Denham—trek!” cried Mak, nodding his head, and using his spear to indicate the direction.
