"My dear duke," said he to the Duke of Courland, who paid him a visit in June, 1786, "if, on your return to Courland, you should hear of a vacancy among the night-watchmen, I beg of you to reserve the place for me, for, I assure you, I have learned the art of watching at night thoroughly." But he wished to employ his hours of wakefulness in the night for the good of his people, and ordered that the members of his cabinet, who had been in the habit of coming to his room with their reports at seven o'clock in the morning, should now assemble there at four. "My condition," said the king, when he acquainted the three members of his cabinet with his desire, "my condition necessitates my giving you this trouble, but it will be of short duration. My life is on the decline, and I must make the most of the time which is still allotted me. It does not belong to me, but to the state."[14] Yes, his life was on the decline; but for a long time his heroic mind found strength to overcome the weakness of the body. At times, when the physicians supposed his strength was entirely exhausted, and that the poor, worn-out figure sitting out on the terrace under the burning July sun, and yet trembling with cold, would soon be nothing more than the empty tenement of the departed soul, he would gather the energies of his strong and fiery mind together, and contend successfully with the weakness of the body. Thus it was in the month of April, when his physicians believed him to be at the point of death. He suddenly recovered one morning, after a refreshing slumber, arose from his bed, dressed himself, and walked with a firm step down the stairway to the carriage, which he had ordered to be held in readiness to drive him out; he entered the carriage, but not with the intention of returning to the palace of Potsdam, but to drive to his dear Sans-Souci, to take up his residence there for the summer.
