"I prefer it open," said Abel, rudely.

The passenger behind was cognizant of all that passed.

"Madam," he said, "will you exchange seats with me?"

She rose and took the rear seat while the gentleman seated himself beside Abel. He was a stout man, and filled more than half the seat. Abel looked disgusted.

"Now, young man, close that window!" said the stout man, in a tone of command.

Abel obeyed, but it was with great unwillingness. He did not dare to do otherwise.

"It is very close," he grumbled. "I like a little air."

"There is no other open window on this side the car. If the others can stand it, you can."

"I wish people would mind their own business," grumbled Abel, peevishly.

"Look here, young man, if you give me any more of your impudence I will give you a thrashing!" said the stout man, sternly.
