THREE:The nephew of Elizabeth, and her successor, Peter III., was a very warm admirer of Frederick. One of his first acts was to send to the Prussian king the assurance of his esteem and friendship. Peter immediately released all the Prussian prisoners in his dominions, entered into an armistice with Frederick, which529 was soon followed by a treaty of alliance. The two sovereigns commenced a very friendly correspondence. Frederick returned all the Russian prisoners, well clothed and fed, to their homes. The change was almost as sudden and striking as the transformations in the kaleidoscope. On the 23d Peter issued a decree that there was peace with Prussia, that he had surrendered to his Prussian majesty all the territorial conquests thus far made, and had recalled the Russian armies.Frederick, as Crown Prince, had been quite methodical in the distribution of his time, and had cultivated rigid habits of industry. Now, fully conscious of the immense duties and cares which would devolve upon him as king, he entered into a very systematic arrangement of the employments of each hour, to which he rigidly adhered during nearly the whole of his reign of forty-six years. He ordered his servants to wake him at four o��clock every morning. Being naturally inclined to sleep, he found it hard to shake off his lethargy. The attendants were therefore directed, every morning, to place upon his forehead a towel dipped in cold water. He thus continued to rise at four o��clock, summer and winter, until an advanced age.
