miles, it was deemed prudent to build a ship theoretically able to travel at least three times that distance. We found we could carry, after everything else necessary had been put aboard, about 6,000 pounds, or three tons, of gasoline for the motor. If we were to attempt a speed of 30 miles per hour, equal to the highest velocity of the winds possible to be encountered, we should need an engine of 250 horsepower. The fuel-consumption of such an engine would be 175 pounds per hour. With 6,000 pounds of fuel we could run about 34 hours, or a total of 1,000 miles, not equal to the distance from our base to the Pole and return. But if we were to reduce the speed to 18 miles an hour, that could be attained with an engine of 70 horsepower, a fuel consumption of 50 pounds per hour, and at this rate 6,000 pounds of gasoline would give us 120 hours of motoring, or a radius of action of more than 2,100 miles.

It was also found that in some respects the Arctic regions presented a field less favorable
