COST OF STEAM: OCEAN MAIL SPEED.
MISAPPREHENSION OF THE HIGH COST OF STEAM MARINE PROPULSION: VIEWS
OF THE NON-PROFESSIONAL: HIGH SPEED NECESSARY FOR THE DISTANCES IN
OUR COUNTRY: WHAT IS THE COST OF HIGH ADEQUATE MAIL SPEED: FAST
STEAMERS REQUIRE STRONGER PARTS IN EVERY THING: GREATER OUTLAY IN
PRIME COST: MORE FREQUENT AND COSTLY REPAIRS: MORE WATCHFULNESS
AND MEN: MORE COSTLY FUEL, ENGINEERS, FIREMEN, AND COAL-PASSERS:
GREAT STRENGTH OF HULL REQUIRED: ALSO IN ENGINES, BOILERS, AND
PARTS: WHY THE PRIME COST INCREASES: THEORY OF REPAIRS: FRICTION
AND BREAKAGES: BOILERS AND FURNACES BURNING OUT: REPAIRS TWELVE TO
EIGHTEEN PER CENT: DEPRECIATION: SEVERAL LINES CITED: USES FOR
MORE MEN: EXTRA FUEL, AND LESS FREIGHT-ROOM: BRITISH TRADE AND
COAL CONSUMPTION.
THE NATURAL LAWS OF RESISTANCE, POWER, AND SPEED, WITH TABLE: THE

FUEL, VARIES AS THE CUBE OF THE VELOCITY: THE RATIONALE:
