"Thought you'd be off somewhere when the Colonel sent for you, old man," he said. "Well, I could go with you, but I feel absolutely rotten. Look here," and Barrington opened his coat and displayed the tops of two soda-water bottles, "I managed to get hold of these. Take one."

"No, thanks," replied Kenneth. "You want them a jolly sight more than I do."

"But you must," persisted Rollo. "It's fearfully hot to-day. Besides, I think I can get hold of some more."

"All right," agreed his chum reluctantly, and taking one of the bottles he placed it in the outside breast-pocket of his coat, resolving to restore it intact upon his return.

The request of the Colonel of the 9th Regiment was most essential. To the north of Omal was a gap of nearly two miles in the Belgian line, as a portion of one of the brigades had failed to take up its allotted position. Omal was a salient angle in the defenders' formation, and should the village be carried by the Germans the Belgian army would be split asunder by the wedge-like advance of their far more numerous foes.

Although the country was fairly open Kenneth rode cautiously. It was a nerve-racking ordeal, since every bush or tree might be affording concealment to the Uhlans, who were known to have already penetrated far into the country. Almost as dangerous were the Belgian guerrillas, who often fired indiscriminately upon any man in a uniform that they failed to recognize.

But beyond being twice stopped by Belgian patrols and made to produce his military pass, Kenneth reached his destination without being molested. He delivered his message, receiving a reply that a machine-gun detachment would be sent off as quickly as possible, and set off on his return journey.

Perhaps the fact that he had but recently passed along the same road without difficulty made him slightly reckless. He increased his speed till the motor-cycle was travelling at nearly forty miles an hour.

Soon he came to a straight, narrow road lined with gaunt trees—one of the avenues that are a common feature in the eastern part of Belgium. Suddenly he gave a gasp of surprise. A horseman had just appeared at the farthermost end of the avenue. At first the lad took him to be one of the Belgian lancers, whose similarity to the German Uhlans was somewhat pronounced, but a rapidly nearing view assured him that the man was one of the enemy.

Another Uhlan joined the first. They both lowered their lances and waited.
