Thus appealed to, she came forward and stopped, still standing off a
little way, but near enough to see, gazing at the shining copper caps on
the cylinders, at the bright rods and gears.

"It looks intricate," said Mr. Ditmar, "but really it's very simple. The
gasoline comes in here from the tank behind--this is called the
carburetor, it has a jet to vaporize the gasoline, and the vapour is
sucked into each of these cylinders in turn when the piston moves--like
this." He sought to explain the action of the piston. "That compresses
it, and then a tiny electric spark comes just at the right moment to
explode it, and the explosion sends the piston down again, and turns the
shaft. Well, all four cylinders have an explosion one right after
another, and that keeps the shaft going." Whereupon the most important
personage in Hampton, the head of the great Chippering Mill proceeded,
for the benefit of a humble assistant stenographer, to remove the floor
boards behind the dash. "There's the shaft, come here and look at it."
She obeyed, standing beside him, almost touching him, his arm, indeed,
brushing her sleeve, and into his voice crept a tremor. "The shaft turns
the rear wheels by means of a gear at right angles on the axle, and the
rear wheels drive the car. Do you see?"

"Yes," she answered faintly, honesty compelling her to add: "a little."

He was looking, now, not at the machinery, but intently at her, and she
could feel the blood flooding into her cheeks and temples. She was even
compelled for an instant to return his glance, and from his eyes into
hers leaped a flame that ran scorching through her body. Then she knew
with conviction that the explanation of the automobile had been an
excuse; she had comprehended almost nothing of it, but she had been
impressed by the facility with which he described it, by his evident
mastery over it. She had noticed his hands, how thick his fingers were
and close together; yet how deftly he had used them, without smearing the
cuffs of his silk shirt or the sleeves of his coat with the oil that
glistened everywhere.

"I like machinery," he told her as he replaced the boards. "I like to
take care of it myself."

"It must be interesting," she assented, aware of the inadequacy of the
remark, and resenting in herself an inarticulateness seemingly imposed by
inhibition connected with his nearness. Fascination and antagonism were
struggling within her. Her desire to get away grew de
