THE citizens of Nicomedia, Sir, have expended three millions three hundred and twenty-nine sesterces[1035] in building an aqueduct; but, not being able to finish it, the works are entirely falling to ruin. They made a second attempt in another place, where they laid out two millions.[1036] But this likewise is discontinued; so that, after having been at an immense charge to no purpose, they must still be at a further expense, in order to be accommodated with water. I have examined a fine spring from whence the water may be conveyed over arches (as was attempted in their first design) in such a manner that the higher as well as level and low parts of the city may be supplied. There are still remaining a very few of the old arches; and the square stones, however, employed in the former building, may be used in turning the new arches. I am of opinion part should be raised with brick, as that will be the easier and cheaper material. But that this work may not meet with the same ill-success as the former, it will be necessary to send here an architect, or some one skilled in the construction of this kind of waterworks. And I will venture to say, from the beauty and usefulness of the design, it will be an erection well worthy the splendour of your times.
