He felt sick and weary. His wound had induced a fever, which made him somewhat light-headed. He stopped running, and trudged doggedly along, in what direction he knew not.

How long he wandered he never knew, but he halted when he came to a donga; for a fire, burning brightly, pulled him up.

He saw the glare of the fire when some distance from it, and conjectured that a party of Boers or British Irregulars on trek had encamped for the night in the donga.

The figures of several men, evidently asleep, were seated round the fire, while some distance away from the latter, a number of horses were picketed, and grazing upon the sparse grass.
