XLVII. Trajan to Pliny
CARE must be taken to supply the city of Nicomedia with water; and that business, I am well persuaded, you will perform with all the diligence you ought. But really it is no less incumbent upon you to examine by whose misconduct it has happened that such large sums have been thrown away upon this, lest they apply the money to private purposes, and the aqueduct in question, like the preceding, should be begun, and afterwards left unfinished. You will let me know the result of your inquiry.
