Hartman held the crowd for a good two hours, then he called, "That's all, boys! Come again!"
"All? Nothing stirring," answered several voices. "Begin over again, Hartman. You can collect another nickel from us as we go out."
There was laughter and applause and not a soul offered to leave. In the darkness Hartman was heard to laugh in return and shortly the first film appeared again. Fields of corn shimmered in the wind. Cows grazed in quiet meadows. The audience stared again, breathlessly. Suddenly from without was heard a long-drawn cry. It was like the lingering shriek of a coyote. Few in the hall had heard the call before, yet no one mistook it for anything but human.
"An Apache yell!" exclaimed an excited voice.
There was a sudden overturning of benches and Pen and Jim were forced out into the street with the crowd.
An arc light glowed in front of the hall. Under this the crowd swayed for a moment, uncertain whither to move. Jim held Pen's arm and looked about quickly.
"I don't know where you will be safest, Pen. I wish I'd heeded the itching of my thumb and taken you home an hour ago."
"Jim," said Pen, "I certainly like your parties. They are full of surprises."
"You are a good little sport," said Jim, "but that doesn't make me less worried about you. Hang onto my arm now like a little burr."
He began to work his way through the crowd. "I don't want to attract their attention," he said. "They will follow me like sheep."
