"Me an' Stewart'll shin attend to that," growled Mac, hearing the suggestion with ill-concealed delight.

We were now entering the outskirts of the pigmy forest, and Phil and I took the lead of our caravan with firearms ready in case of attack; while Mac and Stewart, leading their charges warily in our tracks, peered suspiciously into the densest shadows as they passed. The shrubs were of much greater height than we had expected, and soon they surrounded us in thick even growths through which we steered an erratic course with difficulty.

I was about to call a halt when a thick pile of withered branches, propped against the lower heights of some half-dozen close-growing trees, arrested my attention. "A windbreak! Go slow!" I cautioned those in the rear; but soon we found that we were in the midst of quite a number of these rude shelters, all of which seemed to be of very recent erection. "There is evidently a tribe in the vicinity," I said to Phil, who was gazing at the strange contrivances with much curiosity, and noting how differently they were constructed from the crude wind-barriers met during the earlier part of our journey.

"They appear to work on some design here," he remarked thoughtfully; "the branches are interlaced, and the construction might ultimately evolve into a kind of hut or wigwam."

"I am much more concerned about the whereabouts of the population," I said, and I glanced apprehensively through the trees; then we resumed our march. A few minutes more passed in silence as we proceeded with ears alert for the slightest sound.

We were, as nearly as I could guess, about midway through the forest when Mac suddenly gave a yell of mingled joy and surprise.

"Haud on! Haud on!" be shouted. "I see niggers richt forrit a wee bit. Come on, Stewart, an' we'll shin catch are or twa speecimens."

Mac's information was correct. A convenient gap in the foliage had not been overlooked by him, and his sharp eyes had quickly taken in the view directly ahead. His warning had scarcely been given when we crashed through a maze of windbreaks and entered a clearing in the thicket, and there, in the centre of the open space, fully a dozen hideously scarred and painted warriors stood with spears and boomerangs upraised, gazing in our direction. Mac and Stewart were now forcing past me, and it took Phil and me all our time to restrain their ardour. We had instinctively retired into the shelter of the brush, and none too soon, for a hail of spears rustled through the willowy branches and stuck fast without doing any damage.

"Their spears may be poisoned," I said to the indignant pair. "You've got a different sort of savage to deal with in these latitudes."
