The Mayor turned round sharply, and his face was purple. He walked straight to the door; but, suffering the attendant to precede him along the corridor, he came back with a rapid stride, and, clenching his hands, and, with a voice thick with passion, cried, "Some day or other I will make you smart for this, as sure as my name's Dick Avenel!" "Avenel!" repeated Egerton, recoiling, "Avenel!" But the Mayor was gone. Audley fell into a deep and musing reverie which seemed gloomy, and lasted till the attendant announced that the horses were at the door. He then looked up, still abstractedly, and saw his letter to Harley L'Estrange open on the table. He drew it towards him, and wrote, "A man has just left me, who calls himself Aven --" in the middle of the name his pen stopped. "No, no," muttered the writer, "what folly to reopen the old wounds there," and he carefully erased the words. Audley Egerton did not ride in the Park that day, as was his wont, but dismissed his groom; and, turning his horse's head towards Westminster Bridge, took his solitary way into the country. He rode at first slowly, as if in thought; then fast, as if trying to escape from thought. He was later than usual at the House that evening, and he looked pale and fatigued. But he had to speak, and he spoke well. THE RISE, POWER, AND POLITICS OF PRUSSIA.[1] If there is such a thing in diplomacy as a natural ally, Prussia is the natural ally of England. Each possesses exactly what the other wants--the power of Prussia consisting in an immense army, the power of England in an unrivalled fleet: for though the British troops have shown themselves at least equal to any troops in the world, the genius of the nation looks chiefly to naval pre-eminence; and though, in the course of time, Prussia may be in possession of naval honours, nothing can be clearer than that its present strength depends on its soldiery. The close alliance of England with Prussia is now a century old. We find the great Lord Chatham taking the most open interest in the successes of Frederick II., and establishing the principle that the independence of Prussia is essential to the balance of Europe. At the beginning of the eighteenth century, the north of Germany was divided among a cluster of petty sovereignties--of all forms of a national system the surest to foster political intrigues, to invite the intermeddling of foreigners, the one to offer the strongest inducements to invasion, and to provide the feeblest means of defence. The formidable power of France, within twenty miles of England, must always fix the eye of the English statesman; and no more essential operation for our national tranquillity could be conceived than the solid establishment of a kingdom on the northern frontier of France, which might make that proverbially impetuous and ambitious nation aware, that an attempt to assault England could not be made without incurring the hazard of an assault on her own most exposed frontier.
