Frank followed the direction of Sammy's finger and saw the invalid with a broad grin on his face standing at the open window.
Both boys shook their fists at him, at which Bob's smile broadened. Then he yawned, closed his eyes and with long breaths made his chest rise and fall as though in peaceful slumber.
"Oh, if I only had that putty blower with me now," muttered Sammy, "I'd take that peaceful look off his face in a hurry."
"Wouldn't we just!" snapped Frank.
They started to find something to throw at the tantalizing figure at the window. But Bob, though shamming sleep, was keeping a sharp lookout beneath his lowered lids, and before the boys could find anything to throw the window came down, and with a last grin and a mocking flourish, Bob disappeared.
CHAPTER III
GETTING READY
Bob thought it best to stick close to his room for the rest of the day. Part of this decision was due to his mother's advice and to the fact that he really did feel tired after the fright and excitement of the morning. But part was due to the feeling that he had better let the boys cool down from the putty blower incident.
As a result of his long rest, he appeared at the supper table that evening as bright and gay as a lark.
"Bob seems to be quite like himself again to-night," remarked Mrs. Bouncer. "You see, boys, there was no real reason for you to be so anxious and worried about him as you were this morning."
