"Part of a Roman Aqueduct. Aqueducts form one of the most characteristic features of Roman architecture. Although these simple successions of gigantic arches, which stretch for miles, have no pretensions to artistic beauty, yet their wonderful size and extent bear witness to the vast conceptions of Roman genius."

"Interior of Fort Putnam. This little sketch is a view of the remains of the casemates, or vaults, of Fort Putnam. There were nine originally, but only six remain in a state of fair preservation. They were built of brick and covered with stone; were twelve feet wide and eighteen feet deep, with an arched roof twelve feet high. Each one had a fire-place, and they seem to have been used for the purposes of barracks, batteries, and magazines. In the center of the fort is a spring, that bubbles up in a rocky basin. The whole interior is very rough, it being the pinnacle of a bald, rocky elevation."—Lossing, 1851
