A shadow of apprehension seemed to have fallen on the company. Men glanced up in silence and read in each other’s eyes their own ominous thoughts. Max noticed the change which had come over the others, and inquired as to the reason. Old Schalk sent again for him, and quietly told him the facts as they stood, and left him to draw his own deductions.

At midnight the newly married couples were escorted to their respective wagons, which were standing within a short distance of each other, by a party of young men and maidens. After some uncouth romping and unrefined jokes the escort returned to the Hattingh camp. Contrary to usage the party broke up at once, the different families returning to their respective camps, silent, or whispering to each other the forebodings which they felt.

Afterwards a few of the Boers met as a sort of informal council to discuss the situation and decide as to what was best to be done under the circumstances. The meeting took place at the Hattingh camp, and Max was present. It was settled that a party of six men should start at once for Inkruip. After resting there until daylight they would take on the spoor of the cart through the dunes. The dune route being the shortest cut to Koos Bester’s camp, there was no necessity for sending a party round by the road.

Of course the most urgently necessary thing to do was to interrogate Koos himself. The wind had not blown with any degree of violence since the date of the departure of the missing man, so there would be no difficulty in finding and following the spoor.

During the discussion several very suspicious circumstances came to light. These were all more or less trifles, but, under the circumstances, they became significant. One had noticed Koos walking by himself, muttering, and with hands convulsively clenched. Another had seen him look at Nathan with a terrible expression. Then the killing of the horses. It was well known that Nathan had been in Koos’ company when Gert Gemsbok had been killed. Over and over again the young man who had passed Koos on his way from the dunes was interrogated and cross-examined, but his story could not be shaken. Every one felt satisfied that a tragedy had taken place, and was eager to clear up the mystery.

Within an hour the party, under the leadership of Oom Dantje van Rooyen—who rode the identical horse that was supposed to have killed Gert Gemsbok—had started. Inkruip was reached shortly before dawn. Here a halt was made. The most slender man was made to go down the inclined shaft for the purpose of filling the water-bottles. At the first glimmer of dawn the saddles were again placed upon the horses.

The spoor of the cart lay as clearly defined as if it had only been made on the previous day. It is a peculiarity of the Desert sand that if the wind has not happened to blow hard it retains a spoor distinctly for weeks, or even months.

Shortly after starting it was found that the ordinary course through the dunes had been departed from; the spoor trended away to the left, towards Bantom Berg, and led through a tract which, according to the patriarch of the party, had never been crossed by a vehicle before.

“Allemachtig!” said Oom Dantje, as he ploughed through sand which nearly reached his horse’s knees, “no wonder he killed two of his team!”

More and more the spoor trended towards Bantom Berg. The day was cool, a light breeze blowing from the south, so neither men nor horses were much distressed. Suddenly the spoor curved towards a gap in the right-hand dune. In climbing to this the men, with one accord, dismounted from their horses. When they reached the middle of the gap they stood still to recover breath.
