LXIII. Trajan to Pliny
I AGREE with you, my dear Pliny, that there seems to be no other method of facilitating the placing out of the public money than by lowering the interest; the measure of which you will determine according to the number of the borrowers. But to compel persons to receive it who are not disposed to do so, when possibly they themselves may have no opportunity of employing it, is by no means consistent with the justice of my government.
