"Wait!" cried Arnold. "I can put out the fire and save your Lamb."

"How!"

"With my fire engine! It has real water in it, and I'll pump some on the
paper and save your Lamb from burning up. Watch me, Mirabell, but don't
go near the blaze!"

The piece of paper, close to the Lamb on Wheels, was now sending up a
bright blaze. It would have been pretty if it had not been so dangerous.

Arnold quickly wheeled his fire engine as close to the blazing paper as
he felt it was safe to go. The engine had a little pump on it, as I have
told you, and it spurted out real water, with which it was now filled.

"Toot! Toot! I'm a fireman, and I'm going to put out a real fire!" cried
Arnold.

He pressed back the little catch that held the pump from working. There
was a whirring sound as the wheels spun around, and then the little
rubber hose on the pump of the engine filled with water.

A moment later a small stream spurted out, and Arnold aimed it right for
the piece of blazing paper. The water fell in a small shower on the
fire, and then with a hiss and spluttering, and sending up a cloud of
smoke, the paper stopped burning.

"Toot! Toot! The fire is out!" cried the boy, making believe blow his
engine whistle. "Now your Lamb is saved, Mirabell."
