“You’re in for a surprise tonight,” said Mr. Lewis, as the youths retired.
“What is it?” asked Joe.
“Wait and see,” smiled his father.
The “surprise” did not make itself known the first part of the night. In fact, Bob and Joe forgot all about what Mr. Lewis had said so soundly did they sleep.
But about two in the morning they were awakened by a hideous noise which was unlike anything the youths had ever heard before. That it was the call of some wild animal they did not doubt, but just what creature could cry out in such tones they had not the slightest idea.
The noise was repeated again and again, always nearer. Finally Bob jumped out of bed and bounded to the window.
“Of all things!” he cried, gazing out intently. “Joe, come here—quick!”
Joe needed no urging. Like a flash he had joined his comrade.
“Why—it’s a hyena!” he gasped. “And there’s another—and another. Gosh! They’re right out in the middle of the street.”
