The island is for the most part hilly, indeed almost mountainous, for it rises at one place nearly three thousand feet above the sea. The valleys and lower slopes are rich and fertile, producing good fruit and fair wine, and the views are often of great beauty. The fisheries are of some importance, especially that of the tunny. Porto Ferrajo, the chief town, is a picturesquely situated place, on the northern side, which still retains the forts built by Cosimo I. to defend his newly obtained territory, and the mansion, a very modest palace, inhabited by Napoleon. "It must be confessed my isle is very little," was Napoleon's remark when for the first time he looked around over his kingdom from a mountain summit above Porto Ferrajo. Little it is in reality, for the island is not much more than fifteen miles long, and at the widest part ten miles across; and truly little it must have seemed to the man who had dreamed of Europe for his empire, and had half realized his vision. Nevertheless, as one of his historians remarks, "If an empire could be supposed to exist within such a brief space, Elba possesses so much both of beauty and variety as might constitute the scene of a summer night's dream of sovereignty." At first he professed to be "perfectly resigned to his fate, often spoke of himself as a man politically dead, and claimed credit for what he said on public affairs, as having no remaining interest in them." A comment on himself in connection with Elba is amusing. He had been exploring his new domain in the company of Sir Niel Campbell, and had visited, as a matter of course, the iron mines. On being informed that they were valuable, and brought in a revenue of about twenty thousand pounds per annum, "These then," he said, "are mine." But being reminded that he had conferred that revenue on the Legion of Honor, he exclaimed, "Where was my head when I made such a grant? But I have made many foolish decrees of that sort!" He set to work at once to explore every corner of the island, and then to design a number of improvements and alterations on a scale which, had they been carried into execution with the means which he possessed, would have perhaps taken his lifetime to execute. The instinct of the conqueror was by no means dead within him; for "one of his first, and perhaps most characteristic, proposals was to aggrandize and extend his Lilliputian dominions by the occupation of an uninhabited island called Pianosa, which had been left desolate on account of the frequent descents of the corsairs. He sent thirty of his guards, with ten of the independent company belonging to the island, upon this expedition (what a contrast to those which he had formerly directed!), sketched out a plan of fortification, and remarked with complacency, 'Europe will say that I have already made a conquest.'"
