Explanation of Map.
"Take the road to Bulawayo from Vryburg.
"Ride about one hundred miles to a village called Ngami; there turn aside eastward into the veldt. Head straight for a conical hill fifteen miles distant from the road and visible from Ngami. At the foot of the mountain is a sandy plain covered with rocks and occasional thorn bushes. Between the highest thorn bush and the slope of the hill is an open space of sandy soil about two acres in extent, and covered with scrubby grass. Within this area I have planted four posts. The treasure is buried at a spot within the space defined by these four posts."
Jack Henderson and I rejoiced greatly when we off-saddled that night ten miles ahead of the others. This would give us a good start of them, and, unless we had our own lack of energy to blame, we should never allow them to make up the difference. We were to have first dig, after all! We drank a little hot brandy and water in memory of our crocodile; for to him, we agreed, we owed the advantage we had now gained. But for his good offices our friends would certainly have pushed on farther.
"Perhaps," I suggested, "it was all a trick—their camping there, I mean—and they are even now at our heels and coming up hand over hand!"
"By Jove! you may be right, Peter," said Jack. "I had not thought of it. I'll tell you what, man; it won't do for both of us to sleep at the same time. We must take watches—at all events just now, while we are in the neighbourhood of these bad characters!"
We were to discover before very long that we could not afford to camp out in these African forests without setting a watch, even when far away from bad characters of the biped persuasion! There are some very shady characters in Bechuanaland that walk on four feet, and perform all manner of wickedness under the cover of night! We had not realised this fact as yet, but we were to realise it pretty soon. Nevertheless, in compliment to the poor opinion we held of the Strongs and their ways, we agreed to divide our night into two parts, and that one of us should sleep while the other watched, and vice versâ at "half time."
I was not sleepy, and undertook the first watch, and a right creepy function I found it. Those who have never slept out of their own beds would scarcely believe in how many unexpected and unrecognisable voices old Mother Night can speak. In the heart of an African forest she has tongues innumerable, and, moreover, all of them weird and startling, while some are absolutely terrifying.
We had built up a good fire, and had taken the precaution to pile up an ample supply of fuel almost at hands' reach from the spot at which I lay with my toes to the blaze. But when it became necessary to rise from my place and walk two yards to the pile of firewood in order to add fuel, I must confess with shame that I was so thoroughly cowed and frightened by a feeling of supernatural awe, brought on by the thousand weird and startling noises to which I had lain and listened for two hours or more, that I could scarcely summon sufficient nerve to assume an erect attitude, but lay trembling on the ground endeavouring to gather the courage which had left me, a prey to unworthy feelings of horror.
"However," I reflected, "if I do not keep the fire up, all these awful beasts that are now prowling about in the darkness and dare not come near will become bolder, and"— This thought settled it, and I arose, sweating with foolish terror, and piled a mass of dry material upon the languishing flames at my feet.
