His absence accounted for the loss of the camel, and perhaps the horse, but what had become of the Arab guard?

He certainly would not have absconded with the slave, for he had left valuable property behind him.

There was no time for exchanging surmises over this mystery. Pursuit must be instantly made for the recovery of slave, camel, and horse.

The Arab sheik detailed four of his followers to this duty, and they hasted to make ready for their departure. They would start as soon as the light of day should enable them to see the course the missing animals had taken.

All believed that the fugitives would have to be sought for in a southerly direction; and therefore the caravan would have to be further delayed in its journey.

While making preparations for the pursuit, another unpleasant discovery was made. Two ship’s muskets, that had been taken from Golah’s party, were also missing.

They had been extracted from a tent in which two of the Arabs had slept, two of the four who were now preparing to search for the missing property.

The sheik became alarmed. The camp seemed full of traitors; and yet, as the guns were the private property of the two men who slept in the tent, they could not, for losing them, reasonably be accused of anything more than stupidity.

Contrary to the anticipations of all, the tracks of the lost animals were found to lead off in a north-westerly direction; and at about two hundred yards from the camp a dark object was seen lying upon the ground. On examination it proved to be the Arab who had been appointed night guard over the douar.

He was stone dead; and by his side lay one of the missing muskets, with the stock broken and covered with his own brains.
