"Highness! Baron? I? But since when have I become a baron?"
"Since I made you one. You will start at nine o'clock to-morrow; your letters of credit will be ready at eight."
Frederic could only bow and utter his thanks; he bowed deeply, gratefully thanked the grand duke and left the room.
The next morning at ten o'clock he was in the train and by the evening he was in Berlin. His arrival was immediately announced to the new king. The new king replied that he would receive him the following day at the castle Of Potsdam.
On the morrow Frederic, in his court suit, started for Potsdam and arrived at the castle. But to his great astonishment he learnt that the king had just gone away and had left only his intendant to represent him.
Frederic's first idea was to return to Berlin; but he remembered that it was this official who had entertained him so kindly and courteously two years before at the castle of Rheinstein. He did not want to appear ungrateful or offended, so had his name sent in accordingly. But while crossing the ante-room he observed a full-length portrait of the king. He stopped for an instant stupefied. His Majesty resembled his intendant as one drop of water resembles another. The truth now dawned on Frederic. It was the king's brother himself who, to-day reigning as King William I, had received him at the castle of Rheinstein, who had acted as his guide, had kept him to dinner, who had won three games of chess out of five, and had made him sleep in the Landgrave Philip's bed—who had offered his influence at court, and who on taking leave of him had promised not to forget him.
He understood now why he had been chosen by the Grand Duke of Weimar to carry his congratulations to the king; why the Grand Duke of Weimar had made him a baron, why the king had appointed a meeting at Potsdam, and why finally His Majesty had returned to Berlin, leaving his intendant only to represent him.
His Majesty wanted to enjoy another day like that they had passed together at Rheinstein. Frederic was a good courtier, and was ready to contribute all in his power to this caprice. He entered as if he had no suspicion, greeted his host like an old acquaintance, only showing the respect due to an older man, thus recalling the scene which had left such a pleasing influence on his mind.
The intendant made excuses for His Majesty, and invited Frederic to pass the day at the castle of Potsdam, an invitation which was accepted like the one at Rheinstein. He again offered his services as cicerone, took him into the mausoleum, and showed him the tomb and the sword of the Great Frederic.
A court carriage was ready waiting for them, and they went to see the castle of Sans-Souci, which is only two miles from Potsdam. It was here, it will be remembered, in the park of this château that the famous mill was situated which its owner refused to sell to Frederic II, and which caused the king to exclaim when the miller gained his lawsuit, "So there are still judges at Berlin!" In the sequel the descendants of the stubborn miller were softened and sold their mill to William I, who, wishing to preserve it as a monument of the occurrence, refused to allow it to be demolished.
