CHAPTER VI
THE SCREAM IN THE WATERFALL
“How did this happen, Mr. Porter?” demanded Dr. Byrd sternly, yet with an unmistakable quaver in his voice.
“I—I don’t know, sir,” stammered the manual training instructor. “I thought I heard his voice among the others on the way home.”
The fact was, Mr. Porter thought no such thing. He was merely frightened lest he be held responsible if anything serious had happened to Kenyon while the boy was in his charge. He felt guilty. He knew that he ought to have called the roll to determine if all were present before starting back for the school.
“Did anybody see Hal or hear his voice on the way back?” called out the doctor addressing the crowd of boys now gathered closely around him. No one had.
“Maybe he’s gone into the dining-room,” suggested Mr. Porter in an unnatural tone.
“No, he didn’t do anything of the sort,” returned the doctor. “I’ve been sitting out here for ten minutes waiting for you. Not a boy has entered this building in that time.”
There was an uncomfortable silence for a few moments, and then the doctor continued:
“If anything has happened to that boy I’m going to find out who’s responsible.”
