"Aye-aye, sir."

A riot of shouting and trampling floated up from below, presently, and
the uneasy steering of the boat soon showed that she was getting "down by
the head."

The three men in the pilot house began to talk in short, sharp sentences,
low and earnestly. As their excitement rose, their voices went down.
As fast as one of them put down the spy-glass another took it up--but
always with a studied air of calmness. Each time the verdict was:

"She's a gaining!"

The captain spoke through the tube:

"What steam are You carrying?"

"A hundred and forty-two, sir! But she's getting hotter and hotter all
the time."

The boat was straining and groaning and quivering like a monster in pain.
Both pilots were at work now, one on each side of the wheel, with their
coats and vests off, their bosoms and collars wide open and the
perspiration flowing down heir faces. They were holding the boat so
close to the shore that the willows swept the guards almost from stem to
stern.

"Stand by!" whispered George.

"All ready!" said Jim, under his breath.
