Both father and son had become by this time fully satisfied that their tastes and characters were so different that it was not best for them to live near each other. The prince spent much of his time with his flute. He also engaged in quite a wide range of reading to occupy the listless hours. Works of the most elevated and instructive character especially interested him, such as history, biography, moral and intellectual philosophy, and polite literature in its higher branches of poetry and the drama. “What mankind have done and been in this world,” writes Carlyle, “and what the wisest men, poetical or other, have thought about mankind and their world, this is what he evidently had the appetite for--appetite insatiable, which lasted him to the very end of his days.” It is unquestionable that the mental discipline acquired by this elevated course, to which he consecrated so diligently his hours, prepared him for the wonderful career upon which he soon entered, and enabled him to act with efficiency which filled Europe with his renown. It appears, moreover, that Fritz devoted himself very assiduously to his military duties, earnestly studying the art of war, and making himself familiar with the achievements of the most renowned commanders. His frugal father allowed him but a very meagre income for a prince--not above four thousand five hundred dollars a year. With this sum it was scarcely possible to keep up even the appearance of such an establishment as belonged to his rank. Such glimpses as we get of his moral and social developments during this period are not favorable. He paid no respect to the claims of religion, and was prone to revile Christianity and its advocates. He was particularly annoyed if the chaplain uttered, in his sermons, any sentiments which the prince thought had a bearing against the sensual indulgences and the wild amusements of himself and his companions. On one occasion the chaplain said in his sermon, “There was Herod, who had Herodias to dance before him, and he gave her John the Baptist’s head for her pains.” The prince assumed to make a personal application of this. Herod meant the Crown Prince; Herodias, his boon companions; and John the Baptist was the chaplain. To punish the offender, the prince, with several brother officers, went at night, smashed the windows of the chaplain, and threw in a shower of fire-crackers upon him and his wife, who was in delicate health, driving them in dismay out into the stable-yard. The stern old king was very indignant at this conduct. Grumkow affirms, we hope falsely, that the prince threw the whole charge upon his associate officers, and that they were punished for the deed, while he escaped.
