Note 222 — CHAP. XIV.

The Romans constructed their roads with large masses of stone closely layed together: each piece was often six or seven feet long and carefully squared. The road to Caerwent, formed on such a foundation, though passing through a low swampy country, is observed to be uncommonly compact and dry. Thus the utility of that once great people’s work is transmitted through the constant wear of fifteen centuries; and excites the admiration of even our own enlightened age.
