The arrangement of this business had been variously and frequently altered. Augustus allowed the Senate to appoint commissioners; then, when corrupt practices were suspected in the voting; men were chosen by lot for the office out of the whole number of prætors. This did not last long, as the lot strayed away to unfit persons. Claudius then again appointed quæstors, and that they might not be too lax in their duties from fear of offending, he promised them promotion out of the usual course. But what they lacked was the firmness of mature age, entering, as they did, on this office as their first step, and so Nero appointed ex-prætors of approved competency.
