Even fools have hours in which they do not care to laugh. Frohlich, semper nunquam traurig, as the motto ran on a medal struck in his honour, was in such a mood that day that he was not fröhlich but sour as vinegar. He would not confess it, but he liked the times of Augustus II better than those of his son.

But the habit of being amusing to order enabled him to be merry when he appeared before the King.

Besides being witty, Frohlich was a very able conjuror, and it was just then more easy for him to begin by some trick than a witticism.

Kneeling before the King, Frohlich said that he ran so fast that his throat was dry. He took off his key and asked if his Majesty would be kind enough to permit him to strengthen his forces by a draught of wine. The King clapped his hands and told a page to bring a bottle.

In the meantime Frohlich employed himself cleaning his key which was a little rusty, and from which he was going to drink, complaining that he seldom used it now. The page stood with the bottle ready to pour in the wine, when Frohlich looking at the bottom of his key, grew frightened at seeing something in it.

'Who would have expected,' he exclaimed, 'that a bird would build a nest in it?' And a canary flew out of the key. The King laughed; but that was not all; there was still something more in the key, and the fool took out a pile of ribbons, six handkerchiefs, a candle, and a handful of nuts. Then he said that not being certain that there was not an enchanted princess in the key, he would prefer to drink the King's health from a glass. After some refreshment, the fool began to amuse the King by imitating well-known actors.

The entertainment lasted about half an hour. The King laughed, but Frohlich noticed that in spite of his apparent mirth, he was uneasy, perplexed and distracted. He wondered what the cause could be, when, to his surprise, the King went to the farthest window, and motioned to him to follow.

There was something so mysterious and unusual in this that Frohlich was alarmed. He followed the King, however, to the window, where he was standing, looking round undecided and alarmed.

The fool could not solve the riddle.

'Frohlich, listen,' said the King in a whisper, 'h'm! laugh aloud, laugh, but listen to what I am going to say, Do you understand?'
