With an angry bellow, Mr. Green Hat leaped to his feet, knocking down one of the waiters. Four others rushed to the spot. The five promptly assailed Mr. Green Hat, and were swiftly reinforced by the one who had been floored.

But the stalwart, active brawler proved to be too much for the combined force of the waiters. As if they had been so many reeds, Mr. Green Hat brushed them aside with his fists.

"Grab the bloomin' rotter and throw 'im h'out!" bellowed a "Tommy Atkins," as the British soldier is collectively known.

A new note, in a decidedly American tone of protest, rose above the uproar.

"How dare you? What do you mean, fellow?" demanded a young man in a gray traveling suit, glaring up from the floor, to which he, an unoffending occupant of an aisle seat, had suddenly been hurled.

It was too much for Dan Dalzell, who promptly attempted to seize Mr. Green Hat as that individual, with the momentum of a steam roller, rushed up the aisle.

Dalzell reached out a hand to grip Mr. Green Hat by the collar. All too promptly a heavy fist smote Dan in the chest, knocking him back into the arms of Dave Darrin. Dave himself could not act quickly enough to avenge the blow that had been dealt his chum, because Dan's body blocked the way.

Four or five British soldiers at the rear of the little theatre tried to intercept Mr. Green Hat as he dashed up the aisle. Three of the "Messrs. Atkins" went to the floor, under the seats, while the others were brushed aside, and Mr. Green Hat reached the street.

"Stop that thief!" roared the young man in the gray suit. "He has robbed me!"

By this time Dalzell was again on his feet and out in the aisle. He sprinted for the street, followed closely by Dave Darrin. The young man in the gray suit, his face pallid, plunged after the young naval officers.
