“That will be a horrible bother,” said Dean, as the boys, rifle over shoulder, strode off a little to the right of the straight course so as to take their chance of anything that might spring up from one of the clumps of dwarf trees which were being avoided by the waggon drivers. For these carefully kept away from anything that might impede their progress, which was towards the first rocky eminence of any size they had seen, save on more distant hunting excursions, since they had left the forest behind.

“What, building up a kraal, or zareba, as he called it?” said Mark.

“Yes. You see, we shall be tired enough without having that to do. But it must be done.”

But just at sundown the spot at which Mak had been aiming was reached. It was one of the regular kopjes of the African plains, but fairly verdant, being well furnished with dwarf trees and loose, rugged patches of rock that offered themselves for protection, while a gurgling source of water gushed out at the foot of the largest mass of granite, foamed away amongst the stones for about a hundred yards, forming several clear pools, and lost itself in a muddy, trampled little swamp which showed plenty of signs of being visited by the herds of antelope which roamed the veldt.

One of the first things done was the making of a hurried survey of the kopje, Mak at once bending to his task of leading the travellers, rifle in hand, to the examination of every spot that suggested the possibility of its being used as a lair by any dangerous cat-like beast. But no lion sprang out, and there was nothing suggestive of danger till Mak led the searchers to where the stream spread out for a while before it sank down into the sand.

Here there were plenty of traces of antelope of various kinds, their footprints showing out distinctly and indicating the ease with which a watcher could get a shot. But the next minute the thoughts of all were occupied by their guide stopping short and pointing out the plainly marked spoor of a lion.

This, however, proved to be evidently of some days’ standing, but it was enough to add energy to the efforts made in having the waggons dragged up close to a mass of rock where they could form part of the protection needed and lessen the necessary labour in shutting in the beasts.

Every man had his own work to do, and even with the extra toil of strengthening their camp it was not long before the fire was blazing well, the cattle grazing upon the rich grass in the neighbourhood of the pools, and their guide, being satisfied that they had no unpleasant neighbours, now beckoned to the boys and pointed to the highest portion of the granite kopje, suggesting that they should follow him and have a climb.

The mass of granite, formed of huge, tumbled together blocks, was easily accessible, and the doctor followed them when they began to ascend, till the highest point was reached and they stood sweeping the vast expanse around which now lay plain in the beautifully limpid air.

During the day a soft, hot haze had shut off the more distant objects, but now everything showed up refracted, so that the distant hillocks and clumps of trees seemed quite near, lit up by the soft glow left by the sun that was now below the horizon.
