68 Piazza Poli, October 17th. - We left Viterbo on the 15th, and proceeded, through Monterosi, to Sette Verse. There was nothing interesting at Sette Verse, except an old Roman bridge, of a single arch, which had kept its sweep, composed of one row of stones, unbroken for two or more thousand years, and looked just as strong as ever, though gray with age, and fringed with plants that found it hard to fix themselves in its close crevices.
