"Oh, that was an inspiration," chuckled Devar.

"An inspiration founded on a solid basis of fact. Now, out with it!"

"Well, I was a year at Heidelberg, you know, and a fellow there told me that one evening, in a café at Temesvar, a student kicked up a shindy by singing that song. In less than a minute an officer had been stabbed with his own sword, and a policeman shot, and it took a squadron of cavalry to clear the street. He learnt the blessed ditty, out of sheer curiosity, and I picked it up from him."

"What is it all about?"

"I don't know. I believe it tells the Austrians their real name, but I couldn't translate a line of it to save my life."

Curtis leaned back in the car and laughed.

"You are by way of being a genius," he said. "I have seen a crowd go stark, staring mad because some idiot waved a black flag, but that was a symbol of the Boxer rebellion, and it meant something. In this instance, among people so far away from their own country, one would hardly expect——"

He broke off suddenly, and leaned forward.

The car had just entered Madison Square, at the junction of Broadway and Fifth Avenue, south of 23rd Street. A Columbus Avenue street-car had halted to allow traffic to pass, and a gray automobile which was coming out of Fifth Avenue had been held up by a policeman stationed there. Curtis's attention was caught by the color and shape of the vehicle, and in the flood of light cast by the powerful lamps and brilliant electric devices concentrated on that important crossing, he obtained a vivid glimpse of the chauffeur's face.

"Devar," he said, and some electrical quality in his voice startled his mercurial companion, "tell your man to overtake that car and run it into the sidewalk. The driver is 'Anatole,' and it is our duty to stop him!"
