was annoyed. If somebody wanted to go through the train, he must get up.

A girl came out of the other car and seizing the rails looked down. She
was in the light, and Lister remarked that she did not wear traveling
clothes; he thought her small, knitted cap, short dress, and loose
jacket indicated that she had come from a summer camp. Then she turned
her head and he saw her face was rather white and her look was strained.
It was obvious that something had disturbed her.

The girl did not see him, and while he wondered whether he ought to get
up she put her foot on the step and leaned out, as if she weighed the
possibility of jumping off. She swung back when the cars lurched round a
curve, and the measured roll of wheels changed to a sharp, broken din.
The train was running on to the trestle and Lister saw the water shine
below the platform. He got up, and moving quietly, seized the girl's arm
and pulled her from the rails.

"A jolt might throw you off," he said.

She looked up with a start and the blood came to her skin, but she gave
him a quick, searching glance. Lister was athletic, his face was bronzed
by frost and sun, and his look was frank. She lowered her eyes and her
color faded.

"Does the train stop soon?" she asked.

"If the engineer's lucky, we won't stop until he makes the next
water-tank, and it's some distance."

She turned with a quick, nervous movement and glanced at the door.
