The magnificence displayed by the Romans in the construction of aqueducts was not confined to the capital. Wherever Roman colonies were established, it would appear that vast sums were expended in providing the community with a suitable supply of water. Ruins of aqueducts built by the Romans may still be seen at many points in Spain, France, Africa, Greece, and even England can point to the ruins of a water tower built by this prolific school of Roman engineers. At the present time there are probably one hundred or more structures of this kind in existence, some of which are in daily use, supplying water to inhabitants of communities for whose ancestors they were built centuries ago.

(The miles above given are Roman miles, of 4,854 feet. The entire length of aqueduct in English miles would be 398.) [Illustration: Aqueduct of Segovia, Spain] The aqueduct of Segovia, Spain, is one of the most perfect and magnificent works of the kind remaining. It is built without mortar, is entirely of stone and of great solidity. The piers are 8 feet wide by 11 feet deep, and where the aqueduct approaches the city it attains a height of about 100 feet. This aqueduct is over 2,400 feet long, is built in two tiers of arches and although almost eighteen hundred years old, still supplies water to the city. Of the 109 arches, however, 30 are of modern construction, being reproductions of the ancient arches. [Illustration: Water Tower and Roman Ruins, Chester, England]
