TWO: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 king��s 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.

THREE:With the utmost secrecy Frederick matured his plans. It could not be concealed that he was about to embark in some important military enterprise. The embassadors from other courts exerted all their ingenuity, but in vain, to ascertain in what direction the army was to march. Though the French had an embassador at Berlin, still it would seem that Voltaire was sent as a spy, under the guise of friendship, to attempt to ferret out the designs of the king. These men, who did not profess any regard to the principles of religion, seem also to have trampled219 under feet all the instincts of honor. Voltaire endeavored to conceal his treachery beneath smiles and flattery, writing even love verses to the king. The king kept his own secret. Voltaire was not a little chagrined by his want of success. In his billet of leave he wrote: THREE: THREE:Gradually the secret treaty which allied France, Bavaria, and Prussia, and it was not known how many other minor powers, against Austria, came to light. Two French armies of fifty thousand men each were on the march to act in co-operation with Frederick. England, trembling from fear of the loss of Hanover, dared not move. The Aulic Council at Vienna, in a panic, ��fell back into their chairs like dead men.�� The ruin of Maria Theresa and the fatal dismemberment of Austria seemed inevitable.��We are alone,�� Fritz replied, ��and I will conceal nothing from you. The queen, by her miserable intrigues, has been the source of our misfortunes. Scarcely were you gone when she began again with England. She wished to substitute our sister Charlotte for you, and to contrive her marriage with the Prince of Wales.
