"Splendidly, according to Dr. Barkley's latest report," replied Dudley. "If any fellow deserves the D.C.M. it's he."

"And a little bird whispered to me," continued Laxdale, "that a certain member of the antient and accepted order of the Lone Star Crush did a jolly risky thing—fetching water under enemy fire."

Wilmshurst coloured hotly.

"Rot!" he ejaculated. "Fritz couldn't see me. They were putting up a lot of small arms ammunition, of course. No, that's nothing; almost forgot about it, in fact."

But if Wilmshurst had dismissed the incident from his mind the water had not forgotten him. The poisonous germs in the non-filtered liquid were doing their lethal work, and that evening the subaltern was down with a severe bout of malaria.

In a covered dhoolie Wilmshurst was sent down to a hospital base-camp. With him went Rupert, who, on the setting in of the reaction following his release, was on the verge of a nervous breakdown.

Within a couple of months Dudley was back with his battalion. Many times he bitterly reproached himself for being out of action for that period simply because he did not exercise sufficient restraint when he drank the tainted water. He realised that he alone was to blame, while most of the trouble fell upon the shoulders of his brother platoon-commanders, who already had their full share of work and responsibility.

He found the battalion at a place twenty miles further away from the Karewenda Hills than the kraal where he had played so conspicuous a part in its defence.

"You needn't have been so rattled about it, old boy," declared Spofforth. "You've missed none of the fun, for the simple reason that there hasn't been any. A fortnight ago we were within sight of Twashi. There was a Belgian column operating on the north-west side. It looked as if we were going to do something great, when we had to retire through lack of provisions. It appears that a few Huns got away and started playing the deuce with our lines of communication; put the kybosh on a couple of convoys and generally made things unpleasant."

"Rather," agreed Laxdale. "I've been hungry many a time, but now I know what it means to have to tighten one's belt. I'll qualify for the Army Light-weight Championship yet."
