Nathan Clifford, United States v. Lawson — Opinion of the Court
“ It was provided by that act that whenever the annual emoluments of any collector, after deducting the expenses incident to the office, amounted to more than $5,000, the surplus should be accounted for and paid into the treasury. Districts for the collection of the customs were, at a later period, divided into two classes, usually denominated the enumerated and the non-enumerated ports, and the maximum rate of compensation to collectors was diminished. ”
