It is generally admitted that the coasts of Etruria did not suffer from malaria whilst the ancient Tyrrhenian cities were prosperous. The excavations made recently in connection with the railways have revealed a complete system of subterranean canals, which formerly drained the whole of the Maremmas. Populonia and other large cities, of which only a few ruins are found now, could certainly not have existed if the climate had been as unhealthy as at present. The ancient Etruscans were famous as hydraulic engineers. They embanked torrents, drained swamps, and rendered the country cultivable, but their engineering works were allowed to decay soon after they had been subjected, and the country returned to its primitive savageness. On the other hand, there are many towns {248} which were considered healthy during the Middle Ages, but are now desolated by fever. Massa Maritima, to the south-west of the Moutieri mountain, was rich and populous as long as it maintained its republican liberties; but no sooner had it been enslaved by Pisans and Sienese than its drainage works were allowed to fall into decay, and in the end it found itself reduced to the “shadow of a town.” Sanitary works carried out recently have brought back some of its ancient prosperity. Amongst the causes which have contributed most materially towards a deterioration of the climate may be mentioned the destruction of the mountain forests and the rapid increase of alluvial lands resulting from it. The monasteries of Tuscany, which until quite recently were the owners of the fish-ponds in the Maremmas, energetically protested against the construction of embankments or other drainage works, which they conceived would interfere with their cherished Lenten food. Several of the inland towns rejoiced in the possession of some unhealthy swampy tract, to which obnoxious persons might be banished with a certainty of their dying. Even the Kings of Spain established a penal establishment at one of the most deadly spots on this coast, and banishment to Talamone, at one time a flourishing port of the Republic of Siena, was tantamount to a sentence of death. Many attempts were made to reclaim these lands. Macchiavelli and other statesmen of Tuscany thought that the former salubrity of the climate could be restored by merely repeopling the country. Colonists were sent for from other parts of Italy, and even from Greece and Germany, but they soon succumbed to the climate. Since that time considerable progress has been made in rendering these marshy districts more salubrious. Trees have been planted, and, in combination with proper drainage, they have rendered many districts habitable which were not so formerly. Populonia is a case in point. Follonica, where there are furnaces in which the iron ores of Elba are smelted, is likewise looking up, though its inhabitants still fly the place on the approach of the fever season. * * * * *
