A con- duit or channel for conducting water from one place to another. More particularly applied to struc- tures of masonry and tunneling for the conducting of water from distant sources to large cities through tubular conduits. Aqueducts were extensively used in the Roman empire, and many of these ancient structures still remain. They were constructed of stone or wood, sometimes tun- neled through hills and carried over valleys and rivers on arches, much of the labor upon them being usele ly ex- pended, from a mistaken idea of the nece ity of a per- fectly level course. The aqueduct of Segovia, originally built by the Romans, has 159 arches, is in some parts built in two tiers 100 feet or more in height, and is an admirable monument of ancient engineering. One of the most re- mark able aqueducts of modern times is that of Marseilles, to which city it conveys the waters of the river Durance from a distance of about 58 miles, of which 10 miles con- sists of tunnels, and a considerable portion is traversed by means of viaducts of great height and length. This aque- duct was built between 1839 and 1847, and supplies water in such abundance that the environs of Marseilles, formerly Aquila of birds established by Bri on in 1760, but having no characters by which it can be exactly defined. The name has been loosely applied to eagles and other large diurnal raptorial birds which have no tooth of the beak. It is now restricted and somewhat definitely applied to eagles having booted tarsi, that is, having the shank more or le completely feathered. Such are the golden eagle, A. chrysaetus, of Europe and North America; the spotted eagle, A. nævia, of Asia and Europe; the im perial eagle, A. heliac a, of the same region; the Ru ian eagle, A. mogilnik, etc. See cut under eagle. 2.
