A small monkey came and ran along above their heads and his chattering attracted others, until soon there were many monkeys around them. They did not seem very much afraid of the boys, nor were they unfriendly. They were merely curious. And they were always eating; a fact which drove the boys nearly crazy with hunger.

They watched carefully to discover what the monkeys ate, for they knew that what the monkeys ate with safety, they might eat; but when they discovered that the bill-of-fare appeared to consist quite largely of caterpillars they changed their minds. After a while they saw one of the monkeys gather fruit from a tree and eat it with great relish and they lost no time in clambering up into the branches of that same tree and searching for more of the fruit. It did not taste very good, but it was food and stopped the gnawing pangs of hunger, and its juices helped to satisfy their thirst.

When they had eaten they continued their search for the railway and found it easier to travel through the trees though they were, as yet, far from perfect at it. The food had given them renewed hope and they were quite sure now that they would soon reach the twin bands of steel that would mean rescue, for even if their train had left, there would be other trains along, which would surely stop at sight of two white boys. They might not have felt so much confidence had they dreamed that they were travelling deeper and deeper into the forest, directly away from the railway. Dick, who was in the lead, suddenly voiced an exclamation of satisfaction and relief.

"Here's the old trail!" he cried. "Now we can make some time."

"Gee, but it's good to get your old feet on the ground again," said Doc as the two boys stood again on solid footing. "Come on! Now let's beat it."

With brisk steps they set off along the game trail that ran in the same general direction they had been travelling, positive now that they were on the right road. Doc, his spirits rising to the occasion, broke into a gay whistle.

Ahead of them Zopinga came to an abrupt halt. For an instant he stood, listening intently, then he dropped to his hands and knees and placed his ear against the ground and remained there for a moment, motionless. When he arose, he still remained in a listening attitude, straining every faculty to interpret the sounds that were approaching him along the trail. Just before the boys came into sight the savage warrior stepped into the green wall of the jungle trail. The leaves and branches dropped back, forming an impenetrable screen behind which Zopinga waited.

The boys came confidently on, while Zopinga adjusted his shield upon his left forearm and took a new grip upon his light hunting spear.

The warrior did not see the boys until they were almost opposite him but when he did, the grasp of his spear hand released and a look of relief and satisfaction overspread his black and evil countenance, for he saw that he had nothing to fear from two unarmed white boys. He waited until a turn in the trail took them from his view, then he stepped out into the trail and followed them.

Zopinga was greatly elated. What matter now that his snares had failed to entrap a single victim? Had they all been filled, the reward would not have equalled this windfall that had come to him without the slightest effort upon his part. The victims of his snares he would have had to carry home; but this new quarry walked upon their own legs and, most accommodatingly, were headed directly for the village of the Bagalla.

CHAPTER FOUR

"We must be pretty near the train by this time," said Dick; "unless--"

"Unless what?" demanded Doc.

"We might not be on the right trail," suggested the other. "We might be lost after all."

"Gee, don't say that, Dick. If we're lost now, we'll never find our way out. We'll have to stay in this jungle until we--"

"Until we what?"

"I don't like to say it."

"You mean until we die?"

Doc nodded his head and the boys moved on in silence, each intent upon his own gloomy thoughts. Behind them, just out of sight, came the black warrior, Zopinga. Presently Doc stopped.

"Dick!" he cried. "Do you smell something?"

Dick sniffed the air. "Smells like smoke," he said.

"It is smoke," exclaimed Doc, "and I can smell food cooking, too.

"We're saved, Dick! We're saved! It's the train! Come on!" and both boys broke into a run.

A hundred yards of brisk running brought them to a sudden stop. Before them lay a clearing in the forest at the trail's end. In the centre of the clearing was a palisade of poles surrounding an enclosure. Above the top of the palisade they could see the cone-shaped roofs of grass-thatched huts and, through the open gates that faced them, they could see the huts themselves and half-naked black people moving about. Outside the palisade some women were hoeing in a little patch of cultivated ground.

Dick and Doc took one look at the scene before them before they faced one another in silent consternation.
