“It has been a pretty hard day’s work to-day!” Tom said.
“It is nothing to to-morrow’s, as you will see,” Mr Harvey replied. “Traders consider this defile to be the very hardest passage anywhere in South Africa, and there are plenty of other bad bits too. In many cases you will see we shall have to unload the waggons, and it will be all that a double team can do to pull them up empty. Sometimes of course the defile is easier than at others; it depends much upon the action of the last floods. In some years rocks and boulders have been jammed so thickly in the narrow parts that the defile has been absolutely impassable; the following year, perhaps, the obstruction has been swept away, or to a certain extent levelled by the spaces between the rocks being filled up with small stones and sand. How it is this season, I do not know; up to the time we left I had heard of no trader having passed along this way. I have spoken of it as a day’s journey, but it is only under the most favourable circumstances that it has ever been accomplished in that time, and sometimes traders have been three or four days in getting through.”
Directly the caravan halted Blacking and Jumbo started to examine the defile; it was already growing dusk, and they were only able to get two miles up before it was so dark that they could make their way no further. They returned, saying that the first portion of the defile, which was usually one of the most difficult, was in a bad condition; that many enormous boulders were lying in the bottom; but that it appeared to be practicable, although in some places the waggons would have to be unloaded.
At daybreak the oxen were inspanned, and in a quarter of an hour the leading waggon approached the entrance of the gorge; it seemed cut through a perpendicular cliff, 200 feet high, the gorge through which the river issued appearing a mere narrow crack rent by some convulsion of nature.
“It would be a fearful place to be attacked in,” Dick said, “and a few men with rocks up above could destroy us.”
“Yes,” Mr Harvey said; “but you see up there?”
Dick looked up, and on one side of the passage saw some tiny figures.
“The three hunters and ten of our men with muskets are up there; they started three hours ago, as they would have to go, Jumbo said, five miles along the face of the cliff before they reached a point where they could make an ascent so as to gain the edge of the ravine. They will keep along parallel with us, and their fire would clear both sides; it is not usual to take any precaution of this sort, but after our attack of the other day, and the attitude of the chief and his people, we cannot be too cautious. After passing through the first three miles of the defile, the ravine widens into a valley a hundred yards wide; here they will come down and join us. There are two other ravines, similar to the first, to be passed through, but the country there is so wild and broken that it would be impossible for them to keep along on the heights, and I doubt whether even the natives could find a point from which to attack us.”
They had now fairly entered the ravine. For thirty or forty feet up the walls were smooth and polished by the action of the winter torrents; above, jagged rocks overhung the path, and at some points the cliffs nearly met overhead. Although it was now almost broad daylight, in the depths of this ravine the light was dim and obscure.
The boys at first were awestruck at the scene, but their attention was soon called to the difficulties of the pass. The bed of the stream was covered with rocks of all sizes; sometimes great boulders, as big as a good-sized cottage, almost entirely blocked the way, and would have done so altogether had not the small boulders round them formed slopes on either side. The depths of the ravine echoed and re-echoed, with a noise like thunder, the shout of the driver and the crack of the whip, as the oxen struggled on. The waggons bumped and lurched along over the stones; the natives and whites all worked their hardest, clearing away the blocks as far as possible from the track required for the waggons. Armed with long wooden levers four or six together prized away the heavy boulders, or, when these were too massive to be moved by their strength, and when no other path could be chosen, piled a number of smaller blocks, so as to make a sort of ascent up which the wheels could travel. The waggons moved but one at a time, the united efforts of the whole party being required to enable them to get along. When the leading waggon had moved forward a hundred yards, the next in succession would be brought up, and so on until the six waggons were again in line; then all hands would set to work ahead, and prepare the path for another hundred yards.
