In this substantial volume M. Charles de Mazade has related in a very interesting manner the history of an extraordinarily interesting career. Cavour's career was a short one--the space of eleven years covers the whole of it, and the shorter space of six years witnessed its most striking achievements--but it was nevertheless one of the most remarkable and most active in the annals of statesmanship. Clearly and harmoniously unfolded as it is in these pages, it reads indeed like a romance or a fairy-tale: there seems almost an element of magic in Cavour's inveterate successes. M. de Mazade is a passionate admirer of his hero, and the story loses in his hands none of its brilliancy of coloring. But it needs no retouching: the naked facts themselves are a drama, with all the necessary requisites--the large and moving argument, the skilful performers, the thickening plot, the moment of suspense, the happy dénouement, the attentive auditory. The work accomplished by Cavour had a peculiar completeness and unity: it was a single, consistent task cut out for him by circumstances. It is sometimes said of him that circumstances had more part in the result than the man himself, and that if they had not happened to combine themselves again and again in a peculiarly favorable manner the liberator of Italy would not have been known beyond the limits of the quiet little kingdom of Piedmont. But M. de Mazade points out that Cavour's greatness was precisely in his marvellous talent for making his occasion--for knowing just the way in which to take hold of circumstances. From the day on which, of his own moment and as the first step in a far-seeing plan, he sent, in the face of domestic opposition, a Piedmontese contingent to the Crimean war, he pursued this vigilant culture of opportunity without faltering or going astray. M. de Mazade characterizes him as an extraordinary mixture of prudence and boldness; and these qualities with him always went hand in hand. He knew equally well how to wait and when to act. But it is the element of discretion, the art of sailing with the current of events, that enabled him to effect a great revolution by means that were, after all, in relation to the end in view, not violent--by measures that were never reckless, high-handed or of a character to force from circumstances more than they could naturally yield. For M. de Mazade, Cavour is the model of the moderate and conservative liberal. Liberal he was, as a friend said of him, "as he was fair-complexioned, lively and witty--by birth." But M. de Mazade constantly emphasizes the fact that his liberalism was untinged by the radical leaven, and that if he was a liberator, he had nothing in common with some of the gentry who aspire to this title. All this is very obvious. Cavour was not only the champion of his country: he was also the servant of his king, and his dream was to see Italy not only united, but brought under the sway of the old Piedmontese crown. He often said,
