THREE:Fritz had now attained eighteen years of age, and Wilhelmina twenty-one. Fritz was very fond of music, particularly of his flute, upon which he played exquisitely, being, however, careful never to sound its notes within hearing of his father. A celebrated music-master from Dresden, by the name of Quantz, was his teacher. He came occasionally from Dresden and spent a week or two at Potsdam, secretly teaching the young prince.67 The mother of Fritz was in warm sympathy with her son, and aided him in all ways in her power in this gratification. Still it was a very hazardous measure. The fierce old king was quite uncertain in his movements. He might at any hour appear at Potsdam, and no one could tell to what lengths, in case of a discovery, he might go in the intensity of his rage. Fritz had an intimate friend in the army, a young man of about his own age, one Lieutenant Katte, who, when Fritz was with his music-teacher, was stationed on the look-out, that he might give instant warning in case there were any indications of the kings approach. His mother also was prepared, when Quantz was at Potsdam, promptly to dispatch a messenger to her son in case she suspected his father of being about to turn his steps in that direction.Gentlemen, gentlemen, it is of no use to think about it.
