low us."

"Hah!" said Grenville, starting suddenly to his feet, "we'll have
another look at that body," and, followed by his companions, he strode
away down the Pass, but, when the party reached the scene of the
previous day's rencontre, the lifeless remains were nowhere to be seen;
there was the hole, the rock crusted with coagulated blood, but not the
faintest trace of the body they had left behind them a dozen hours
before. Clearly no beast of prey had been responsible for its
disappearance, for the man's gun and ammunition had also been removed.
A lengthy and careful examination of the surroundings revealed nothing;
all was barren rock, without a single sign of its having ever been
pressed by the foot of man, and, with most uncomfortable feelings, the
trio retraced their steps up the Pass, and reached the cave again, weary
and disheartened, as the sun went out with the rapidity peculiar to the
latitudes of Equatorial Africa, at once plunging everything into
darkness that might be felt.

Grenville's active mind was, however, at work upon the incidents of the
day, and he never rested until his party was safely housed in a cave
some hundred yards from the previous location. This night all kept
watch; and well was it for them that they were on the alert, for, just
before the moon got up, the darkness of the Pass was suddenly cut, as if
by magic, with the flash of at least a score of rifles, fired so as to
fairly sweep their old resting-place. Grenville and his companions
crouched down amongst the rocks, straining eyes and ears for sight or
sound of their murderously-inclined foes; but all was as still as death,
and at daybreak the Pass was again, to all appearance, utterly deserted,
only their old cave was strewn with flattened bullets, which had been
fired with murderous precision.

Grenville tried to get Myzukulwa's views upon the events of the night as
they smoked their pipes after breakfast, but the chief was unusually
reticent. "Spooks," he said, "who shot as well as these did were
dangerous; nothing but a spook could shoot like that in the dark."
Leigh was for clearing out altogether; he was as plucky a fellow as ever
stepped, but this sort of thing was enough to shake any man's nerves.
That day was spent in a rigid search which literally left no stone
unturned; but the keenest scrutiny revealed no place of concealment and
no way into the mountain--over it none could go, for that towering wall
of rock would
