Those who had cards of invitation were the guests of the king, and wandered freely through the saloons. Those who came without cards had to content themselves behind the silken ropes stretched across one side of the rooms; by means of this rope an almost invisible and yet an insurmountable barrier was interposed between the people and the court circle. It was difficult to preserve the rules and customs of courtly etiquette in such a vast assembly, and more difficult still to see that every man was received and served as the guest of a king, and suitable to his own personal merit. Crowds of lackeys flew through the rooms bearing silver plateaux filled with the richest viands, the most costly fruits, and the rarest wines. Tables were loaded with the luxuries of every clime and season, and the clang of glasses and the sweet sound of happy laughter were heard in every direction. The king expressed a proud confidence in his good people of Berlin, and declined the services of the police. He commissioned some officers of his life-guard to act as his substitute and play the host, attending to the wants and pleasures of all. Supper was prepared in the picture-gallery for the court circle. But what means this wild laughter which echoes suddenly through the vast crowd and reaches the ear of the king, who looks up surprised and questioning to his master of ceremonies, and orders him to investigate the tumult? In a few moments Pollnitz returned, accompanied by a young officer, whose tall and graceful figure, and whose handsome face, glowing with youth, pride, and energy, attracted the attention of the noblest ladies, and won a smile of admiration from the queen-mother. "Sire," said Pollnitz, "a mask in the guise of a thief, and in the zealous pursuit of his calling, has robbed one of the officers who were commanded by your majesty to guard the public peace and property. Look, your majesty, at our young lieutenant, Von Trenck: in the midst of the crowd, his rich, gold-embroidered scarf has been adroitly removed; in his zeal for your service, he forgot himself, and the merry gnome,--whom Trenck should have kept in order, has made our officer the target for his sleight of hand. This jest, sire, caused the loud laughter which you heard." The eyes of the king rested with an expression of kindliness and admiration upon the young man, and the Princess Amelia felt her heart tremble with joy and hope. A rich crimson suffused her cheeks; it made her almost happy to see that her lover was appreciated by her exalted brother and king.
