"Hi, you!" said Jack haughtily; "hook it, double quick! You're keeping the duke's own corps of irregulars. Sheer out with your bothering carts or it'll be the worse for you."

That was the substance of his speech, a speech that brought a supercilious grin from the young man.

"Si, señor," he said, "but there is time; there is always time."

Jack gripped his meaning with difficulty, and then bubbled over with wrath. Had he commanded cavalry he would have been tempted to ride over the insolent fellow and his obstruction. As it was, he felt he could thrash the man with his whip. But such action was out of the question. Jack fumed and raged, while Andrews grinned secretly. As for the Spaniard, he returned to his cart, finished his cigarette, and then gave the order for the group of vehicles to move forward. But as soon as the corps of irregulars had passed he sent a messenger to call its commander.

"Well?" demanded Jack haughtily, riding back, and meeting the man alone and well away from all others. "What fool's errand have you called me for?"

"Gently does it, Jack. Gently! I'll be frightened," laughed the muleteer, in the purest English. "How are things going?"

The young leader of the composite corps nearly dropped from his horse, and then, bending low, stared at this stranger.

"I'm blistered!" he growled. "Am I standing on my head, or——"

"Don't get frightened," came the grinning answer. "It's Tom, right enough. I'm glad we've met, for it proves my disguise to be good. Not one of the men recognized me, and I gave 'em every chance; even Andrews was hoodwinked. How'll I do?"
