Four trains on this road carry mail daily, two each way, two in a twenty-five-foot mail apartment and two in a thirty-foot mail apartment, an average earning rate of 7.88 cents per car mile.
The passenger cars on this branch carry an average of 24 passengers each, and earn 48 cents per car mile. The average mail apartment furnished is half a passenger coach.
These four apartment cars, at the same rate as the passenger cars (24 cents per mile), would earn $18,029 per year.
The passenger train earnings on the branch are $79,000 a year. The mails demand 17.38 per cent of the facilities, and on that basis should earn for the company $13,730.
The mail earnings were $5,940, this being the annual compensation after a reduction of nine and one-half per cent through the Cortelyou order, requiring the aggregate of 90 weighings to be divided by 105 to ascertain the "average."
