The whole question arose thus. It appears that the Duke of Wellington, whose illustrious reputation and great services entitle him to be heard with the deepest and most reverential respect, has long entertained great uneasiness on account of the undefended state of this country in the case of a hostile invasion. That such an event is likely to take place, no one supposes or has said--that it possibly might take place, very few will venture to deny. The idea is not a new one; for within the range of the present century, preparations have been actually made for that purpose, and that whilst the wonderful power and facilities of steam-navigation were unknown. Fulton--we have seen men who knew him when he was a humble artisan in the West of Scotland--had, despairing of success at home, submitted his models to the French government, who, fortunately for us, did not then appreciate the merits of the invention. Three years afterwards, he started his first steamer on the Hudson in America. The power which our French neighbours had once so nearly within their grasp, at a time when it might have been used to the exceeding detriment of England, became generally known and adopted, and we need not speak of its progress. It has altogether changed the tactics of naval warfare. It can conquer the old difficulties of wind and tide, and it has immensely shortened the period of transit from the continental coast to our own. The security, therefore, of our insular barriers has been materially weakened, and thus far the possibility of an invasion from abroad has been increased. We are not now speaking of the _probability_, which is matter for subsequent consideration.
