Insular Tuscany consists of Elba and several smaller islands, which mark the site of an isthmus that formerly joined the mainland to Corsica, and contribute greatly towards the beauty of the Tuscan littoral.
Elba, once the miniature kingdom of Napoleon, is larger than all the other islands together.[86] An ancient dependency of the Etruscan city of Populonia, Elba rises above the blue waters of the Tyrrhenian a picturesque group of mountains. A narrow and dangerous strait separates its steep coasts from the promontory of Piombino, where passing vessels were formerly obliged to pay toll.
The granitic heights of Monte Capanne, the eastern extremity of the island, {256} attain an elevation of 3,303 feet; the dome-shaped hills of serpentine at the other extremity are 1,600 feet in height, and the centre of the island is occupied by hills of various formations, covered with brushwood. The variety of rocks is very great, taking into account the small extent of the island. Associated with the granites and serpentine, we meet with beds of kaolin, and with marble similar to that of Carrara. Remarkable crystals and precious stones abound to such an extent, that Elba has been likened to a “mineralogical cabinet” on a vast scale.
Formerly, when the sea was infested by pirates, the inhabitants retreated to the recesses of the interior, or to the summits of steep promontories, where the picturesque ruins of ancient fortifications may still be seen. Several of the old inland villages continue to be inhabited; amongst others, that of Capoliberi, the “Mountain of the Free,” which is looked upon as a sort of acropolis. After the suppression of piracy the islanders came down to the marina, or coast, and established themselves in the towns of Porto Ferrajo, Porto Longone, Marciana, and Rio. The resources of the island are considerable, and afford plenty of occupation to fishermen, salt-makers, wine-growers, and gardeners. The inhabitants are hospitable, and, though neighbours of the fierce Corsicans, they possess all the gentleness of Tuscans.
Elba is not, however, so much noted on account of its fisheries, vineyards, salt-works, or commerce, as because of its rich deposits of iron ore. The russet-coloured cliffs of ironstone are visible from the mainland. The huge excavations made by the miners, many of whom are convicts, resemble the craters of extinct volcanoes, and the reddish brown, violet, or blackish colour of the rocks helps the illusion. Of the quantity of ore carried away from here in the course of twenty-five or thirty centuries we can hardly form a conception. The ironstone is bedded in layers, differing in colour according to the nature of the earthy ingredients, and rising into hills 600 and more feet in height, the slopes of which are covered with brushwood (macchie). Shovels and spades are the only mining tools required in clearing away these heaps of ore, of which at least 100,000,000 tons remain. By regular mining operations 500,000 tons might be obtained annually during twenty centuries. The annual produce at present hardly exceeds 100,000 tons. The ore is more particularly suited to the manufacture of steel. Loadstones abound near Capo Calamita. The mariners of the Mediterranean formerly made use of them in the construction of a primitive ship’s compass, by placing them in a piece of cork, which they allowed to float in a basin of water.
The smaller islands of the Tuscan archipelago are—Giglio, with quarries of granite; Monte Cristo, a pyramidal rock rising 2,130 feet above the sea-level; Pianosa, with an agricultural penal settlement; Capraja, with a small town built within an amphitheatre of pink-coloured granite; and Gorgona (987 feet).[87] {257}
V.—THE ROMAN APENNINES, THE VALLEY OF THE TIBER, THE MARCHES, AND THE ABRUZZOS.
That portion of the Italian peninsula which has Rome for its centre may be likened to the trunk of the body, for it is there the Apennines attain their greatest height, and nowhere else to the south of the Po are rivers of equal magnitude met with.[88]
The main rampart of the Apennines runs parallel to the coast of the Adriatic. To the mariner, who sees these mountains rise above the verdure of the littoral region, they have an appearance of the greatest regularity. Summit rises beyond summit, one lateral chain succeeds to the other, and every one of the numerous valleys descends perpendicularly to the coast. The slope throughout is steep, and the geological strata, whether of Jurassic, cretaceous, or tertiary age, succeed each other regularly from the snow-clad summits down to the promontories of the coast. The only irregularity consists in a detached group of hills (1,880 feet) to the south of Ancona, above which the axis of the Apennines changes its direction. This region of Italy is the natural counterpart of Liguria. The position of Ancona corresponds with that of Genoa, and the coast, which extends on the one hand to Emilia, and on the other towards the peninsula of Monte Gargano, may fairly be likened to the “Rivieras” of Genoa, with this exception, that its direction is inverse. The territory between the mountains and the coast is narrow, the littoral road frequently winds round promontories, and the towns extend up the hill-sides. Still this portion of Italy is not as strongly protected by nature as Liguria. Towards the north it expands upon the plain of the Po, whilst the terraces at the foot of the main range of the Apennines afford easy access from the west. During the whole of the Middle Ages and down to our own days neighbouring states have fought for the possession of this territory, which has become known, from this circumstance, as the “Marches;” that is, the disputed frontier districts, where every town is a fortress perched on the top of a hill.
The Apennines forming the boundary between the Marches and Latium, or Rome, like those of Etruria, are grouped in separate mountain masses. The first of these commands the valley of the Tiber in the east; it extends in the north to Monte Comero (3,828 feet) and the Fumajolo, or head-stream of the Tiber, and in the south to Monte Verone (5,006 feet). Though inferior in height to other parts of the Apennines, these mountains are known as the Alpe della Luna. A gap, {258} through which passes the road from Perugia to Fano, separates them from Monte Catria (5,585 feet). At that point the Apennines bifurcate, and two parallel ranges can be traced thence for a distance of 120 miles, as far as the transverse range of the Majella (9,158 feet), which reunites them, and from which radiate the mountains of Southern Italy. These parallel chains belong to the Jurassic and cretaceous formations, and neither of them forms a water-parting, for whilst the Nera and other rivers tributary to the Tiber force themselves a passage through the western one, that on the east is broken by numerous gorges, through which rivers and torrents find their way into the Adriatic. The most considerable of these rivers is the Pescara, which rises on the plateau of the Abruzzos, where it is known as the Aterno, and traverses the eastern range where it is highest. The gorge excavated by this river is sufficiently wide to afford space for a railway joining the Adriatic to the basin of the Tiber.
