"A machine used for clearing out or deepening the channels of rivers or harbors. Dredging-machines are variously constructed, the simplest being like the oyster-dredge described above, only having a perforated cowhide bag instead of the chain-net, and a stronger 'spoon' or iron mouth to the bag." — Chambers' Encyclopedia, 1875

"An artificial channel formed to carry off any stagnany body of water, like the sluices in modern use. Some works of this kind are among the most remarkable efforts of Roman ingenuity. That through which the waters of the lake Fucinus discharged themselves into the Liris, is represented in the preceding woodcut." — Smith, 1873.

"Eddystone is a group of gneiss rocks, daily submerged by the tide, in the English Channel, 9 miles off the Cornish coast, and 14 S.S.W. of Plymouth Breakwater. The frequent shipwrecks on these rocks led to the erection of a lighthouse on them in 1669-1700, but the great storm of Nov. 20, 1703 completely washed it away. Another lighthouse was built in 1706-1709. This was burned in 1755. The next, noted for its strength and the engineering skill displayed in it, was constructed in 1757-1759. The granite was dovetailed into the solid rock, and each block into its neighbors. As the rock in which this tower was built became undermined and greatly weakened by the action of the waves, the foundation of another was laid on a different part of the reef in 1879. Its light is visible in clear weather at a distance of 17 and one half miles."—(Charles Leonard-Stuart, 1911)
