"After luncheon, my dear," observed Frau Müller, "we shall have Herr Müller take you about our city; for Vienna is vastly different from Linz."

Herr Müller joined the party at luncheon at eleven o'clock, which was really the breakfast hour, because Austrian families take only coffee and cakes or rolls in the early morning, eating their hearty breakfast toward the middle of the day, after which they rest for an hour or two, before beginning their afternoon duties.

At two o'clock the three were ready for the walk, for Frau Müller was not to accompany them. Joseph, the portier, an important personage in Viennese life, nodded "A-b-e-n-d" to them, as they passed out the front door of the building, over which he presided as a sort of turnkey. No one may pass in or out without encountering the wary eye of Joseph, who must answer to the police for the inmates of the building, as also for the visitors. And this is a curious custom, not only in Vienna, but other European cities, that immediately upon one's arrival at an hotel, or even a private home, the police are notified, unawares to the visitor, of his movements and his object in being in the city, which reduces chances of crime to a minimum; burglary being almost unknown, picking pockets on the open streets taking its place in most part.

"Of course you know, children," said Herr Müller, as they passed along the broad Kärtnerstrasse, where are the finest shops of Vienna, "you've been taught in school the history of our city, so I need not tell you that."

"Oh, but please do, father," said Ferdinand. "Teresa may not know it as well as I do,"—he hesitated, for he noticed the hurt look in the girl's eyes, and added—"although she may know a lot more about other things."

"Well," began the father, "away back in the times before Christ, a body of rough men came from the northern part of France and the surrounding countries. They were called Celts. They were constantly roving; and so it chanced they came to this very spot where we now are, and founded a village which they called Vindobona. But about fourteen years after Christ, the Romans worked their way northward; they saw the village of the Celts and captured it. They built a great wall about it, placed a moat outside of these fortifications and settled down to retain their conquest. They built a forum, which was a public square where all the business of the city was transacted; and, on one side, they placed their camp or praetorium. To-day, we call the Roman forum the Hohermarkt, just here where we stand now," continued Herr Müller, "and here, where the Greek banker Sina has built this fine palace, stood the Roman praetorium; while here, you see the street is named for Marcus Aurelius, the Roman emperor who was born in Spain and died in this city so many hundreds of years ago."

"I've heard that ever so many times, father," said Ferdinand, "but I never realized it before; somehow it seems as if I could almost see the Celts driven out and the great wall and moat of the Romans."

Meanwhile they had walked on, down the Bauermarkt and reached the St. Stephanienplatz, with St. Stephan's Church in the middle.
