We would ask any or all of those gentlemen who depend upon a general rising, to take the trouble, for some half hour or so, to revert to history. If they do so, and seriously think over the matter, they will speedily be convinced that an invasion is by no means a difficult matter, and that no reliance whatever can be placed upon the co-operation of the undisciplined people, either of the country or the metropolis, in the event of an actual invasion. In fact, judging from history, Paris is literally impregnable compared with London, and yet it has been occupied by the Allies. In 1688, William of Orange, a foreign prince, having no claim to the crown, and against the will of the people of England, whatever may be said of the aristocracy, landed in Britain, advanced to London, and took the throne, without the slightest demonstration of hostility. The population were perfectly quiescent. It was not their business to fight: they paid for an army; and accordingly they allowed the Orangeman to march on, just as they would do to Joinville, provided he desired his troops to be reasonably accommodating and civil. Sack and rapine might undoubtedly provoke resistance; but if ordinary courtesy were used, and more especially if the French proclaimed that they came upon a free-trade errand, and a friendly visit to Mr Cobden, there would be far fewer shots fired, than at the present moment are resounding from the peaceful hedgerows of Tipperary. The next instance we select--omitting minor efforts--is the enterprise of 1745, which peculiarly concerns Scotland, and of which we are by no means ashamed. The heir of the Stuarts landed in the North, supported by no force at all. The clans, to their immortal honour, and a portion of the best Lowland blood of Scotland, maintaining those principles of loyalty which free-trade cannot comprehend, assumed the white cockade, and after thrashing the English army effectually at Prestonpans, marched south, on the desperate errand of displacing the reigning dynasty. And how were they received? It is important to note the idea which the English people had, at that time, of the Highlanders. They considered them a race of cannibals who ate children; so that it was no uncommon matter, when a Highland officer entered a house, to find the mistress on her knees, praying for a Lenten diet, whilst the terrified urchins were all the while concealed beneath the bed. Such is the positive fact; and yet we will venture to say, that there never was, in the history of the world, an instance of a more blameless or more humane invasion. Donald, though quite ready to cleave a bearded Hanoverian to the chin, had an extreme weakness for children, and would not, on any provocation, have insulted a defenceless woman. Had Mr Cobden fallen into his hands, the Highlander, after a due estimate of his physical capabilities, would probably have put him to ransom for a quarter of a pound of tobacco.
