The rifle duel continued for an hour. As Chris had said would be the case, after seven or eight had fallen, as they were trying to make rushes across pieces of ground where boulders afforded no cover, the rest became very cautious, and at last only an occasional shot was heard.

"We will fall back now," Chris said, "for aught we know a party of them may be working round somewhere to take us in rear. We know that they have not got their horses with them, for we can see the spot where they hid them. Still, we do not want to be caught between two fires. Let four on each flank crawl back; keep well among the rocks, and don't let them catch sight of you. We will fire occasionally to let them know that we are still here. When you have got the horses up and everything is ready, whistle, and we will come back to you. It will be a long time before they venture to crawl up and discover that we have gone, an hour most likely, and by that time the cattle will be a dozen miles on their way to Estcourt, and the Boers are not likely to follow them."
