This service demands a twenty-five-foot apartment car each way for which the pay amounts to 7.64 cents per car mile run, or about the fares of two passengers at three cents per mile who may occupy one seat.
The service is six days per week, but the aggregate weight carried in the six days is divided by seven to obtain the Cortelyou "average" on which the pay is based.
The payment for a twenty-five-foot traveling post office is a little over half the pay per mile for a rural route carrier.
