The king nodded affirmatively. "Yes; the road lying through the valley of the Danube is level; the one that leads to Vienna by the Kahlenberg is steep and toilsome."

"But much shorter," added the duke.

"Let us then select the route over the Kahlenberg," answered the king. "Your highness' understands giving sound advice under the garb of a passing observation."

Their conversation was just then interrupted by the appearance of two young horsemen, who bowed respectfully as they rode by. One wore the rich and becoming uniform of the Polish lancers—this was the crown prince of Poland; the other, more simply attired, was Prince Eugene of Savoy—the youngest colonel in the Austrian service.

At a signal from the King of Poland, the youths reined in their horses.

"My son," said the king, touching the Polish prince on the shoulder, "let me congratulate you that you are about to engage the enemy under the command of one of the most distinguished generals of the age."

The duke shook his head, and smilingly addressed Eugene: "Prince of Savoy," said he, "you see before you a king whose least glory is his crown. Let him be your model, and when you confront the enemy let the thought of John Sobiesky's fame urge you to deeds of prowess."

"Your highness," replied Eugene, "not only when I confront the enemy, but every day and every hour of my life, will I look back with emotion to the time when I beheld the two most eminent commanders of the age contemplating each other's greatness without envy, and accepting each other's suggestions without cavil; and I trust that, from the sight, I may receive inspiration as far as lies within my capacity, to emulate their moral as well as their military worth."

"You will ere long have the opportunity of showing us how proximity to John Sobiesky inspires men to valor," replied the duke. "We are about to march to Vienna. Which road would you take, if you had to choose for the army?"

Eugene's large black eyes wandered over the horizon until they rested on the summit of Kahlenberg. "If we gain those heights, we overlook not only our friends, but the entire camp of the enemy."
