The monarch was expected in a few days; for, in the midst, of his various occupations, Frederick, who was at this time extremely intent upon the establishment of the porcelain manufactory at Berlin, found leisure frequently to inspect it in person. The king, however, was prevented from coming at the appointed hour by a review at Potzdam. His majesty had formed the singular project of embodying, and training to the science of arms, the Jews in his dominions{2}. They were rather awkward in learning the manual exercise; and the Jewish review, though it afforded infinite amusement to the spectators, put Frederick so much out of humour, that, as soon as it was over, he rode to his palace of Sans Souci, and shut himself up for the remainder of the morning. The preceding evening an English traveller, who had passed some time at Paris with the Count de Lauragais, in trying experiments upon porcelain clays, and who had received much instruction on this subject from Mr. Wedgewood, of Etruria, had been presented to the king, and his majesty had invited him to be present at a trial of some new process of importance, which was to be made this morning at his manufactory. The English traveller, who was more intent upon his countryman Mr. Wedgewood's fame than upon the martial manoeuvres of the Jews, proceeded, as soon as the review was finished, to exhibit his English specimens to a party of gentlemen, who had appointed to meet him at the china-works at Berlin. {Footnote 2: Wraxall's Memoirs of the Court of Berlin, &c.} Of this party, was a youth of the name of Augustus Laniska, who was at this time scarcely seventeen years old. He was a Pole by birth--a Prussian by education. He had been bred up at the military school at Potzdam, and being distinguished by Frederick as a boy of high spirit and capacity, he was early inspired with enthusiastic admiration of this monarch. His admiration, however, was neither blind nor servile. He saw Frederick's faults as well as his great qualities; and he often expressed himself with more openness and warmth upon this subject than prudence could justify. He had conversed with unusual freedom about Frederick's character with our English traveller; and whilst he was zealous to display every proof of the king's greatness of mind, he was sometimes forced to acknowledge that "there are disadvantages in living under the power of a despotic sovereign." "A despotic sovereign! You will not then call your Frederick a despot?" whispered the English traveller to the young Pole, as they entered the china-works at Berlin. "This is a promising manufactory, no doubt," continued he; "and Dresden china will probably soon be called Berlin china, by which the world in general will certainly be much benefited. But in the meantime look around you, and read your monarch's history in the eyes of those prisoners of war--for such I must call these expatriated manufacturers."
