It was here, yesterday, that I came upon an unexpected sight--an army of workmen engaged in burrowing furiously into the bowels of Mother Earth. They told me that this tunnel would presently become one of the arteries of that vast system, the Apulian Aqueduct. The discovery accorded with my Roman mood, for the conception and execution alike of this grandiose project are worthy of the Romans. Three provinces where, in years of drought, wine is cheaper than water, are being irrigated--in the teeth of great difficulties of engineering and finance. Among other things, there are 213 kilometres of subterranean tunnellings to be built; eleven thousand workmen are employed; the cost is estimated at 125 million francs.
