“Go to it, Ned,” Commander Farragut replied. “Engineer,” he called, “keep the pressure mounting!”

Ned Land made his way to his post. The furnaces were urged into greater activity; our propeller did forty-three revolutions per minute, and steam shot from the valves. Heaving the log, we verified that the Abraham Lincoln was going at the rate of 18.5 miles per hour.

But that damned animal also did a speed of 18.5.

For the next hour our frigate kept up this pace without gaining a fathom! This was humiliating for one of the fastest racers in the American navy. The crew were working up into a blind rage. Sailor after sailor heaved insults at the monster, which couldn’t be bothered with answering back. Commander Farragut was no longer content simply to twist his goatee; he chewed on it.

The engineer was summoned once again.

“You’re up to maximum pressure?” the commander asked him.

“Aye, sir,” the engineer replied.

“And your valves are charged to . . . ?”

“To six and a half atmospheres.”

“Charge them to ten atmospheres.”
