“We’re entering another trap,” said West bitterly, as they led their reluctant ponies along the bed of the stream, fortunately for them too stony for any discoloration to be borne down to show the keen-eyed Boers that someone had passed that way, and at the same time yielding no impress of the footprints of man or beast.

As far as the fugitives could see, the ravine went in a devious course a couple of hundred yards into the eminence, but, as it proved, nearly across to the other side. It was darkened by overhanging trees and creepers, which found a hold in every ledge or crack of the almost perpendicular sides, and grew darker and darker at every score of yards; but the echoing rocks gave them full notice of what was going on near the entrance, the voices of the Boers and the splashing noise of their horses’ feet coming with many repetitions to drown any sound made by their own.

“It isn’t a bad place!” said Ingleborough, as they hurried on, with the ravine growing more narrow and the sides coming more sharply down into the water. “It strikes me that we shall find the water comes out of some cave.”

Five minutes later Ingleborough proved to be quite correct, for they paused at a rugged archway between piled-up fern-hung blocks, out of which the water rushed in a fairly large volume, but not knee-deep; and, upon leaving his horse with his comrade and boldly wading

in, West found that the cave expanded as soon as the entrance was passed, so that the spring ran outward along a narrow stony bed, and on either side there was a bed of sand of considerable width.

“Come along!” said West. “The water gets shallower, and there is a dry place on either side.”

Ingleborough waded in at once, but unfortunately the ponies shrank from following, and hung back from the reins, one of them uttering a loud snort, which was repeated from the interior so loudly that the second animal reared up wildly and endeavoured to break away.

West dashed back though directly and relieved his companion of one of the refractory beasts, when by means of a good deal of coaxing and patting they were finally got along for some yards and out onto the sandy side, where they whinnied out their satisfaction and recovered their confidence sufficiently to step towards the running waters and resume their interrupted drink.

“Rifles!” said Ingleborough shortly, when West unslung his and stood ready, following his companion’s example as he stood in the darkness with his piece pointing out at the bright stream with its mossy and fern-hung framing.
